Editorial The 1st European Network of Excellence for the development of neuromuscular treatments is launched
The kick-off meeting by TREAT-NMD
for Translational Research in Europe – Assessment and Treatment of Neuromuscular Diseases, took place on 18-19 January 2007 at the Genocentre in Evry, near Paris. This 5-year initiative*, involving 21 partner organisations from 11 EU countries, was instigated by the AFM (French Muscular Dystrophy Association) and EURORDIS (the European Organisation for Rare Diseases). The event was coordinated by researchers Kate Bushby and Volker Straub, both from the University of Newcastle, UK.
AFM/Laurent Audinet
Neuromuscular diseases currently affect 200,000 individuals in Europe and are of mainly genetic origin. Besides the AFM, other major European neuromuscular disease players already involved in the Network include the Généthon, the Institut de Myologie, the Italian Telethon and university teams from all over Europe. Bringing together 2000 physicians and scientists from all over Europe, the aim of this neuromuscular network is to encourage experts to establish and share best practice in research and define standards of care in close consultation with the patients and patient organisations affected by these neuromuscular diseases as well as the pharmaceutical researchers and biotechnology companies working with these pathologies, such as Santhera, Prosensa, Genosafe, etc.
The Network will begin by clearly establishing a centre for the coordination of European initiatives to develop new therapies in close partnership with the institutions, industry and patient organisations involved. This Centre will provide a vital link between the exchange and standardisation of therapeutic strategies in the neuromuscular pathology field at international level.
The 4 major international patient organisations leading the fight against Duchenne muscular dystrophy have signed an "International Alliance for Coordinated Research on Duchenne muscular Dystrophy". This partnership which is the first of its kind, aims to develop common strategies, as well as encourage the exchange of scientific and medical knowledge and stimulate R&D. The AFM (France), the Muscular Dystrophy Association (USA), the Parent Project for Muscular Dystrophy and the United Parent Project for Muscular Dystrophy (Netherlands) also hope to extend the partnership to other neuromuscular diseases. This Alliance could serve as a model for the creation of similar partnerships for other rare genetic diseases.

Task Force Update The RDTF state-of-the-art Report on Centres of Reference for Rare diseases in Europe is now online
The latest RDTF report, "Centres of Reference for Rare Diseases in Europe: State-of-the-art in 2006 and Recommendations of the Task Force", is now available at the What’s New section on the updated DG SANCO rare disease pages
and also via the EU Health Portal.
RDTF WG conclusions on European Reference Networks feature in the High Level Group's 2006 Work Report
Following new drafts made in 2006 and since changes discussed at the HLG meeting held on 14 September last year (see last
October’s OrphaNews Europe ), the final version of the HLG’s Report on work carried out in 2006 includes conclusions based on the report by the RDTF WG to assess the added value of European Reference Networks of Centres of Reference (ENCR). The first of the report’s 3 annexes, “Options for a procedure for identification and development of European reference networks”, is based on the integration at the September meeting of this type of network as a working concept for Europe.
In item 2.3 European Reference Networks, the document describes the results of the Working Group’s deliberations on ENCR over the 2005-2006 period and assesses both work undertaken and the resulting recommendations. It also outlines future work plans and suggests that the Working Group remain in close contact with the RDTF and other leading players involved to continue their efforts in this field.
In Annex 1, Options for a procedure for identification and development of European reference networks, the report sets out the general principles of the ERN, stressing the importance of flexibility and the ability to open up to potential new centres where appropriate. The options concerning existing and new specific mechanisms for ERNs are discussed. Item 3 examines how more specialised, “Independent”, centres with a potential to create a future EU Network of Centres of reference can be identified and integrated into the ERN system. The document recommends that mapping exercises, such as the one currently being performed by the RDTF and Orphanet on RD expert centres in the 27 EU Member States, be encouraged to identify existing expert/reference centres in other ERN-related fields.

Health in Europe : a Strategic Approach – Discussion document for a Health strategy
DG SANCO has recently brought out a Discussion document giving readers the opportunity to send in their comments and thereby contribute towards a new general Health Strategy to be adopted by the EC in 2007. This document will cover a 10-year period with a mid-term review. It recognizes the importance of health as a European issue as well as the need for Community action on major health issues. Furthermore, this discussion document notes that EU action provides a valuable impetus for the creation of pan-European networks of expertise enabling the exchange of best practice in rare disease treatments as well as in e-health, nanotechnology and virtual centres of excellence. The document also provides a background as well as key information for a new Health Strategy, identifying developments in health services and health threats.
Readers are invited to send in their suggestions and comments to help set the agenda for this important health strategy by 12 February 2007, ideally using the list of Questions on page 10, to the European Commission

DG Research DG Research has published its first FP7 Calls for proposals
Of the first FP7 Calls for proposalsto be published, one of the Calls for proposals from Cooperation Theme 1 "Health" is of particular interest to the RD community:
The Cooperation Health Theme includes an area dedicated to rare diseases, which will focus over the course of FP7 on Europe-wide studies of natural history, pathophysiology and on development of preventive, diagnostic and therapeutic interventions. This sector will also include rare Mendelian phenotypes of common diseases.
Two topics are currently open in this specific area, with the submission deadline being 19 April 2007 (for details, see the Work programme:
- HEALTH-2007-2.4.4-1: Natural course and pathophysiology of rare diseases (Small or medium-scale focused research projects)
HEALTH-2007-2.4.4-2: Research capacity-building in the field of rare diseases (Coordination or Support action)
The work programme for the Health Theme includes other topics, not specifically dedicated to rare diseases, but which might also be of relevance to rare diseases, such as:
HEALTH-2007-3.4-1: Disease networks of centres of reference (Support action; deadline 18 September 2007).

National & International Policy Developments Other international news NIH has launched a Licensing Opportunities website listing for RD technologies
The US National Institutes of Health (NIH) have recently launched licensing opportunities for RD technologies in the form of technologies available for commercial licensing for RDs or conditions. The listing, which currently features more than 500 technologies of this kind, including drugs, biologics and devices, is available for transfer from the NIH and the FDA to the private sector where future R&D and potential commercialisation may be carried out.
Developed by the Office of Rare Diseases (ORD), and the NIH Office of Technology Transfer (OTT), the aim of this resource is to facilitate the identification of licensing opportunities taken on by pharmaceutical companies and academic institutions and thereby improve the transfer of research advances made from bench to bedside relating to interventions which may ultimately benefit patients. Since the US definition of a rare disease is one with a prevalence of less than 200,000 (cf. one with a prevalence of 1/2,000 in the EU), there are an estimated 25-30 million people living in the USA with a rare disease.
Steve Groft, Director of ORD, believes this new mechanism will help promote public-private collaboration and has the potential to make a real difference for patients: “Because relatively few people are affected by any one rare disease, finding therapies for each poses unique challenges and requires innovative approaches”.
This initiative may be compared with its European counterpart at OrphanXchange.

The US House of Representatives has adopted a draft law on stem cells The US House of Representatives, which is made up largely of Democrats, voted on 11 January to lift restrictions imposed by the US President, George Bush, on research into embryonic stem cells. However, since less than the mandatory two thirds of member votes were cast, Bush has already promised he will impose his veto.

Research in Action New diseases & syndromes Peripheral and Central Hypomyelination with hypogonadotrophic hypogonadism and hypodontia: the 4H syndrome
A dysmyelinating leukodystrophy associating a progressive cerebellous ataxia, a hypogonadotrophic hypogonadism and a hypodontia has been diagnosed in 4 unrelated patients. These symptoms suggest the association of a myelination defect (of the central and peripheral nervous system) and of an endocrinal deficiency of the pituitary gland. The authors suggest naming this new entity “4H syndrome”.

Six members of 3 families from North Pakistan present an extremely rare phenotype: none of them has ever experienced pain. The first case, a 10-year-old child, was identified following his regular “street theatre” performances which involved walking on burning embers, and placing knives through his arms. Through a positional cloning study, Cox et al. have identified different homozygous mutations of the SCN9A gene, encoding Nav1.7, an sub-unit of a voltage dependent sodium channel expressed in nociceptive neurons. This discovery looks likely to result in research into new analgesics which may selectively block this channel.

Gros-Louis et al. have identified 53 patients related to 26 Canadian families manifesting a slowly developing pure cerebellar ataxia and associated with a dysarthry. By positional cloning, different SYNE1 gene mutations have been identified. The gigantic Syne-1 protein (8800 amino acids) was up till now known for its role in the anchoring of myonuclei under neuromuscular junctions. The absence of muscular phenotype in these patients therefore indicates that SYNE1 may instead be especially important in maintaining cerebellum architecture.

The Chanarin-Dorfman syndrome is characterised by intracytoplasmic accumulation of triglycerides, ichthyosis and usually includes a mild myopathy. Mutations in the ABDH5 gene are a possible cause of this disease. Certain patients presenting the symptoms of this syndrome with the exception of ichthyosis do not have any ABDH5 anomalies, the product of which activates the lipase encoded by the PNPLA2 gene. Fischer et al., at the National Genotyping Centre at Evry in France, have sequenced this PNPLA2 gene in 3 patients thereby identifying 4 distinct mutations.

The Joubert syndrome is an autosomal recessive condition characterised by a hypoplasia of the cerebellum associated with hypotonia, delayed development, respiratory problems and anomalies in the eye movements. As in Meckel-Gruber syndrome, an occipital encephalocele and a polydactylia may be observed. This resemblance has led Baala et al. to sequence the genes MKS1 and MKS3, recently isolated in the Meckel-Gruber syndrome. Mutations of MKS3 have been detected in 4 patients with the Joubert syndrome. MKS3 represents the sixth locus implicated in the Joubert syndrome.

Osteogenesis imperfecta constitutes a group of hereditary disorders responsible, in different degrees, for the fragility of the skeleton. Most frequently, gene mutations encoding type I collagen are at the origin of dominant autosomal forms of the disease. However, forms involving recessive autosomal transmission have already been described. CRTAP, a protein required for the post-translational (propyl-3-hydroxylation) modification of type I collagen, is a potential candidate. Barnes et al. have sequenced the gene encoding CRTAP and identified recessive mutations in 3 children with osteogenesis imperfecta.

Trypanosoma evansi is a flagelated parasite which habitually infects domestic mammals. However, an infection in humans has been described recently in India. The innate immunity of humans against a parasite of the same kind, trypanosoma brucei brucei, is due to the trypanolytic activity of the L-I (APOLI) Apolipoprotein. The sequencing of the gene encoding this protein in the Indian patient reveals 2 microdeletions leading to total loss of expression. The infection observed is therefore probably due to an absence of APOLI.

Two independent studies published in Nature Genetics reports on the identification of mutations in the SOS1 gene in patients affected by Noonan syndrome. These patients of short stature have a characteristic facial dysmorphia and congenital cardiac anomalies. Former studies suggest that a deregulation of the RAS-MAPK pathway may be at the origin of this disease’s development. Sequence analysis of genes whose products act before the RAS and ERK proteins has made it possible to identify different mutations of the SOS1 gene, encoding a RAS guanine exchange factor. All the mutations identified to date in the Noonan syndrome currently increase the activation of the RAS-MAPK pathway.

Familial form of hypospadias: nucleotide variations in 4 developmental genes
Hypospadias is caused by a fault in the development of the spongeous body and the urethra. The familial forms of the disease represent 10% of the cases observed. The BMP4 and BMP7 genes have an important role in the embryonic development of the urethra, whilst HOXA4 and HOXB6, over the same time, intervene in the development of the skin in numerous tissues. The sequencing of these genes in 90 Chinese patients has led to the identification of 13 nucleotide variations, 8 of which modify the protein sequence. None of these variations has been found in 380 individual control chromosomes.

European Journal of Human Genetics ; 15 (1) : 23-8 ; Jan 2007 New fundamental research Long-lasting arrest of murine polycystic kidney disease with CDK inhibitor roscovitine
Renal polycystosis frequently exists in a dominant form and in a much rarer recessive form. No treatment is currently available. The products of the genes whose mutations have been involved in these pathologies have been recently localised in primary cilia. Since the ciliary functions are involved in the regulation of the cell-cycle, American researchers have tested the roscovitine action, an inhibitor of cyclin-dependent kinases, on 2 murine polycystosis renal models. A timely treatment is sufficient for minimising renal polycystosis in mice. These results indicate that roscovitine, already used in clinical trials as an anti-cancer agent, constitutes a novel approach for the treatment of recessive renal polycystosis.

A new case of duplication of the locus deleted in the Williams-Beuren syndrome has been identified. The young 13-year-old girl manifests severe difficulties in language in the absence of severe intellectual deficiency. These signs are different from those of patients affected by the Williams-Beuren syndrome, in which hypersociability and growth retardment are observed. These results suggest that the language development is sensitive to a fine dosage of one or several genes carried by this chromosomal region.

Alpha-sarcoglycanopathy is a muscular disorder with a recessive transmission due to a alpha–sarcoglycan deficiency, a transmembranal protein belonging to the complex associated with dystrophin. No treatment currently exists. Researchers from the Génethon in France have built up a recombinant virus encoding human alpha–sarcoglycan under the control of a muscular promoter. Intra-arterial injection of this virus in the limbs of the murine model of this disorder has completely corrected the alterations of the contractile force and stretching. The formation of the sarcoglycan complex and the histological characteristics are also restored. These results suggest that this type of approach can be envisaged for therapeutic purposes.

Mol Ther. ; 15(1):53-61 ; Jan 2007 Ataxia spinocerebellar type I: an increase in the native function of ATAXIN-1 at the origin of the neuropathology.
Autosomal dominant spinocerebellar ataxia type I is caused by the expansion of triplet repetitions encoding glutamines in the SCA1 gene. Lam et al. have demonstrated that its product, ATAXIN-1, when in its normal or pathological form, interacts with the transcriptional repressor Capicua in the mouse’s cerebellum. A mutation of this gene which overrules the neurotoxicity of the protein carrying an expansion of the polyglutamine segment, reduces the association avec Capicua. The neuropathology due to the expansion of triplets therefore seems to depend on the natural function of ATAXIN-1 and not on a possible new function of this protein.

An American team has succeeded in isolating human cells derived from amniotic fluid showing stem cell characteristics. Undifferenciated AFS cells expand extensively and have a typical doubling time of approximately 36 hours (without extracellular matrix or their elements) and are not tumorigenic. They manifest a normal maintenance of the normal number in the length of the telomeres and karyotype. They are multipotent and can thereby be differenciated towards different embryonic germ layers: adipogenic, osteogenic, myogenic, endothelial, neuronal and hepatic lineages. If this study is confirmed, these cells could represent a new potential source of stem cells for therapy.

The QT long syndrome is a disease with an autosomal dominant transmission characterised by ventricular arrythmia and a risk of sudden death. Female predominance has already been observed in this syndrome but was attributed to a greater risk of cardiac arrythmia in women. In this study, the segregation of mutations and parental transmission were analysed in 753 nuclear families. The transmission is not Mendelian: it can be observed that more individuals are affected (57%, p<0,001) than the theoretical proportion and more women than men were affected (55%, p=0,005).

Neurofibromatosis type I is a dominant autosomal disorder characterised by café-au-lait spots and cutaneous neurofibromas. The mutations of the NF1 gene, encoding Neurofibromin, caused the disease. No correlation between the genotype and the phenotype of the patients has been observed to date in the case of small mutations. In this study, 21 unrelated patients not affected by cutaneous or plexiform neurofibroma all carry the same deletion of 3 pairs of bases. This deletion bears the loss of methionin in a well conserved region of the protein. The functional explication of this correlation between the genotype and phenotype is not clarified.

Cerebral cavernomas are vascular malformations which may lead to various neurological problems. Three genes at the origin of this disease’s development have been identified: KRIT1, MGC4607 et PDCD10. Liquori et al. have analysed the prevalence of mutations of each of these 3 genes in a cohort of 63 patients. The mutations of KRIT1 genes, MGC4607 and PDCD10 represent respectively 40%, 38% and 6% of the anomalies detected (no mutation has been detected in 16% of cases). Notably, a deletion of 77,6 kb of the MGC4607 gene is present in 13% of patients. The existence within this gene of a region of hypermutability, rich in repeated sequences could explain this observation.

Genetic testing EuroGentest has established draft guidelines for genetic counselling in Europe
EuroGentest*, has produced a set of draft guidelines for genetic counselling(GC) on genetic testing (GT) across Europe.
The need for these guidelines was clearly identified by a survey carried out over the 2005-06 period on GC legislation, guidelines and practices applied by human genetic societies from 38 European nations. The survey concluded that no direct legislation relating to GC issues existed in most of these countries, although some professional guidelines had been produced in some of the countries without relevant legislation. Six of the countries possess neither legislation nor guidelines. Furthermore, Article 12 of the European Convention on Human Rights and Biomedicine (Council of Europe, 1997) requires appropriate genetic counselling prior to predictive genetic testing however the Convention has not yet been ratified by all Member States.
A group from EuroGentest has collected and analysed international and European guidelines and policies relating to genetic counselling, including GC legislation in EU countries. Two specialist workshops on the subject were organised between May 2005 and September 2006, whilst data was collected from a number of surveys performed. The guidelines, based on the recommendations resulting from this preparation, are currently being circulated to major networks of European experts in the field for discussion and improvement.

Orphan Drugs Launch of EudraPharm, a new European public medicines database EMEA Press Release - 6 December 2006)
EMEA has recently launched EudraPharm, a new public database on information about European medicines. This database, which aims to provide on-line information to all EU citizens on all medicines including veterinary as well as human, is a long-term European project containing information concerns medicines authorised by the EC after assessment by the European Medicines Agency. These new treatments include orphan drugs for rare conditions as well as treatments for cancer, AIDS/HIV, diabetes and neurodegenerative disorders. EMEA expects the base, which will be updated weekly, to become a reference for independent information on all medicines available to the public and is authorised both on the European and the national level. Each indexed medicine will deliver the following information: name, formulation, dosage, therapeutic area, type of administration, pharmaceutical form, domain, authorisation date, name of authorising organisation, authorisation status, authorisation title and available presentations. Currently, research can be carried out on the product name and on certain other information referred to above. New research features are anticipated, along with a future referencing data presentation possibility in the European clinical studies database, EudraCT, in addition to the future availability of the database in all EU languages.
Access EudraPharm: http://www.eudrapharm.eu A 100mg daily dose of Sprycel® has a better performance than 70mg in a twice- daily dose (BMS Press Release - 11 Dec 2006)
Bristol Myers-Squibb presents the results of a phase III study, demonstrating an similar efficiency to that of Sprycel® (dasatinib) in a 100 mg single daily dose, compared to Sprycel® 70 mg in a twice-daily dose. The study also demonstrates that a modification in dosage or posology is associated with a diminution of side effects in patients. Since last June, Sprycel® has been authorised in the USA for lymphoblastic leukemia with Philadelphia chromosome in patients showing a resistance or intolerance to earlier treatments. It has also received a favourable opinion from EMEA in September for the same indication, as well as for chronic myeloid leukemia in patients who are resistant or intolerant to Glivec®.
Orphan Drug policy issues The FDA proposes a regulatory overhaul to expand availability of experimental drugs and clarify permissible charges to patients
Significant regulatory changes were proposed by the FDA last month to increase access to experimental drugs by seriously ill patients with no other treatment possibilities. They also seek to clarify the circumstances and the costs that manufacturers may charge for this type of drug. These would amend the FDA’s Investigational New Drug application (IND) regulation. Availability would be increased for individual patients, small patient groups and larger populations under a treatment plan when no satisfactory alternative therapy exists to diagnose, monitor or treat the disease or condition.
This is not the first time that the FDA has allowed different types of access to experimental therapies. Since the 1970’s, large programmes have given tens of thousands of HIV/AIDS, cancer and cardiovascular disease patients the chance to receive promising therapies before the products were approved for marketing. But a failure of the regulations at that time to describe the full range of programmes available, by which only emergency use for individual patients and widespread treatment use access for large groups of patients was recognised, meant that the FDA is now keen to ensure the necessary revisions are made.
The proposed rules aim in particular to:
modernise regulations to include all circumstances under which access to experimental drugs is permitted
make these drugs more widely available in appropriate situations by establishing new criteria linking the drug to the level of seriousness of the disease and expected number of patients to be treated
revise and clarify current rules regarding the recovery of manufacturer’s experimental drug costs and simplify the cost recovery calculation.
The proposed rules are open for comment for 90 days and may be consulted and commented on via the Center for Drug Evaluation & Research (CDER) here

New designations & authorisations in USA US pharmaceutical regulators report a disappointing year for FDA rare drug approvals
The International Herald Tribune (IHT) reports that 2006 was a disappointing year for drugs approvals in the USA where the lowest number of approvals in nearly 8 years was recorded. Medecines recommended for sales in 2006 and 2005 dropped in number from an annual average of 26 drugs recorded between 2000 and 2006. FDA data shows that the highest number of approvals made was in 1999 with the lowest figure recorded amounting to just 17 in 2002. The number of medicines recommended for sale in both 2006 and 2005 dropped from the annual average of 26 drugs recorded over the past six years. The IHT article notes that the FDA rejected several new drug marketing applications last year, including Genta's Genasense to treat patients with chronic lymphocytic leukemia.

Ethical, Legal & Social Issues Ethics New US legislation for Privacy, Confidentiality and Identifiability in Genomic Research
New legislation for the protection of individuals against potential genetic discrimination in employment and health insurance provision has been introduced in the US House of Representatives . Last month saw the introduction in the House of the (H.R. 493) Genetic Information Nondiscrimination Act . The draft bill text noted that Federal law on genetic discrimination is incomplete and that State laws, which vary greatly, can create discrepancies which confuse both the medical community and the general public. It is widely hoped in the States that more homogeneity in national and basic standards brought about by federal legislation will, in turn, protect the public from discrimination and offer reassurance with regard to fears surrounding this matter. This could lead to more people taking advantage of genetic testing.
It is not the first time that legislation on this issue has been introduced to the House or indeed the Senate (cf. attempts in 2003, 2005 and 2006 whereby one of the two governmental authorities was quashed by the other). However, it is believed this 2007 draft bill may fare better given the new Democratic majority in Congress, if agreements on the text are reached. Other reasons for this optimism were increased by a recent presidential visit to the NIH, at which George Bush spoke out clearly in favour of legislation. If this support is indeed confirmed from all sides then this draft bill looks set to have a far more positive impact than its predecessors with regard to this thorny genetic issue.
A US position statement for genome data-sharing opens up a debate in Europe
The International Genetic Epidemiology Society (IGES) has established a position statement on the sharing of data on genome-wide association studies in response to a NIH Request for Information
entitled “Proposed Policy for Sharing of Data Obtained in NIH-supported or -conducted Genome-Wide Association Studies (GWAS).
Now the IGES proposes to broaden the issue by extending the debate to Europe in order to assess appropriate implementation of the data-sharing guidelines for countries outside the US and thereby establish a comprehensive international framework.

Social issues The Universal Convention for Disabled Rights is adopted
The Universal Convention of Persons with Disabilities, which has been welcomed as a “landmark” treaty for social rights, was adopted on 13 December 2006 after 4 years of preparation. It will be open for signature at the UNO Headquarters in New York on 30 March 2007.
Whilst this Convention does not create any new rights as such, it aims actively to prevent discrimination by ensuring that the fundamental rights of disabled people, identical to those of all non-disabled people, are understood and guaranteed by the States parties concerned. In a message UNO Secretary General Kofi Annan declared that this Convention was the “first treaty on human rights adopted in the 21st century”, while the NGO Handicap International called it a “historic advance”. The Convention provides the estimated 650 million disabled people across the world with legal protection from exploitation and abuse whilst reinforcing their rights regarding health, freedom of movement, education, employment and participation in political life. Article 25 of the Convention notably requests the States Parties to ensure that disabled people benefit from free healthcare of the same quality as care given to non-disabled people.

Dec 2006
Read on
This white paper sets out long-awaited proposals for revision of the current Human Fertilisation and Embryology Act. It also establishes the statutory basis and chronology for a new regulatory body (the Regulatory Authority for Tissue and Embryos) which is expected to be reformed out of the existing Human Fertilisation and Embryology Authority as well as the recently formed Human Tissue Authority with a smaller body incorporating Expert Advisory Panels to provide technical assistance. Other proposed changes include bringing UK law into line with European legislation such as the recent European Tissue and Cells directives . The revised legislation is expected to be introduced initially as a Bill published for scrutiny in the Parliamentary 2007-8 session whilst the revised regulatory body should be up and running by 2009.
