Microcephalic osteodysplastic primordial dwarfism types I and III

Disease definition

Rare disorders characterized by intrauterine and postnatal growth retardation, microcephaly, facial dysmorphism, skeletal dysplasia, low-birth weight and brain anomalies. Although they were originally described as two separate entities on the basis of radiological criteria (notably small differences in pelvic and long bone structure), later reports confirmed that the two forms represent different modes of expression of the same syndrome.
