Type of disease: Rare conditions
Opsismodysplasia is a rare skeletal dysplasia characterized by congenital short stature and characteristic craniofacial abnormalities. Clinical signs observed at birth include short limbs, small hands and feet, relative macrocephaly with a large anterior fontanel (the space between the front bones of the skull), and characteristic craniofacial abnormalities including a prominent brow, depressed nasal bridge, a small anteverted nose, and a relatively long philtrum. Children with opsismodysplasia are at an increased risk for respiratory infections and respiratory failure. This condition is caused by mutations in the INPPL1 the gene. It is inherited in an autosomal recessive manner. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
