Jeune asphyxiating thoracic dystrophy and short-rib polydactyly type III (Verma-Naumoff) are variants of the same disorder.
Jeune syndrome (JS) and short-rib polydactyly syndrome type III (SRP type III) are autosomal recessive disorders characterized by short ribs and polydactyly. They are distinguished from each other by the more severe radiological and histological bone findings as well as the occurrence of facial anomalies, ambiguous genitalia, and occasionally, cloacal abnormalities in SRP type III. We present a family in which two children have mild JS and one has SRP type III as evidence that JS and SRP type III are variants of the same disorder. The intrafamilial variability may reflect the effects of modifying loci on gene expression.
