ORPHA:77298Classification level: Disorder
Prevalence is unknown but less than 30 cases (male and female) have been described in the literature so far.
Genital anomalies (hypospadias, micropenis, and/or cryptorchidism) were reported in most of the male patients. Several other associated anomalies have been described including developmental anomalies of the central nervous system, cardiac defects, vertebral anomalies, growth failure, sensorineural hearing loss, anterior pituitary hypoplasia and hypogonadotropic hypogonadism. Intellectual development was normal in some cases, but mild to significant psychomotor delay has also been reported.
Inheritance is autosomal dominant and the syndrome is caused by heterozygous mutations or deletions in the SOX2 gene (3q26.3-q27).
