KEGG : ³⁶ Opsismodysplasia (OPS) is a rare, autosomal-recessive skeletal dysplasia primarily characterized by growth plate defects and delayed bone maturation. Its clinical features are rhizomelic micromelia and facial dysmorphism, including prominent brow, large fontanels, depressed nasal bridge, and small anteverted nose with long philtrum, as well as short feet and hands with sausage-like fingers. Death secondary to respiratory failure during the first few years of life was reported in the cases originally described but the outcome is now known to be highly variable with multiple long-term survivors. Typical radiographical features include short long bones with markedly delayed epiphyseal mineralization, metaphyseal cupping, short metacarpals and phalanges, and severe platyspondyly. Mutations in the gene encoding inositol polyphosphate phosphatase-like 1 (INPPL1) are found in several families with OPS. However, not all patients have INPPL1 variants suggesting that OPS exhibits genetic heterogeneity.

MalaCards based summary : Opsismodysplasia, also known as opsmd, is related to rickets and hypophosphatemic rickets, x-linked recessive. An important gene associated with Opsismodysplasia is INPPL1 (Inositol Polyphosphate Phosphatase Like 1). Affiliated tissues include bone, and related phenotypes are delayed skeletal maturation and depressed nasal bridge

NIH Rare Diseases : ⁵² 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.

OMIM : ⁵⁶ 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 nasal bridge, a small anteverted nose, and a relatively long philtrum. Death in utero or secondary to respiratory failure during the first few years of life has been reported, but there can be long-term survival. Typical radiographic findings include shortened long bones with delayed epiphyseal ossification, severe platyspondyly, metaphyseal cupping, and characteristic abnormalities of the metacarpals and phalanges (summary by Below et al., 2013 and Fradet and Fitzgerald, 2017).

UniProtKB/Swiss-Prot : ⁷³ Opsismodysplasia: 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 nasal bridge, a small anteverted nose, and a relatively long philtrum. Death secondary to respiratory failure during the first few years of life has been reported, but there can be long-term survival. Typical radiographic findings include shortened long bones with very delayed epiphyseal ossification, severe platyspondyly, metaphyseal cupping, and characteristic abnormalities of the metacarpals and phalanges.
