Description: (OMIM) Opsismodysplasia is a rare skeletal dysplasia involving delayed bone maturation. Clinical signs observed at birth include short limbs, small hands and feet, relative macrocephaly with a large anterior fontanel, and characteristic craniofacial abnormalities including a prominent brow, depressed ...
Clinical Description OMIM Opsismodysplasia was suggested by Maroteaux et al. (1982) as the designation for a skeletal dysplasia that shows late bone maturation; the Greek root for the first part of the word means 'delayed maturation.' The disorder was observed at ...
