" /> Omodysplasia 1 - CISMeF





Preferred Label : Omodysplasia 1;

Symbol : OMOD1;

CISMeF acronym : OMOD1;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Micromelic dysplasia, congenital, with dislocation of radius; Omodysplasia, generalized form; Omodysplasia, autosomal recessive;

Description : Omodysplasia-1 (OMOD1) is a rare autosomal recessive skeletal dysplasia characterized by severe congenital micromelia with shortening and distal tapering of the humeri and femora to give a club-like appearance. Typical facial features include a prominent forehead, frontal bossing, short nose with a depressed broad bridge, short columella, anteverted nostrils, long philtrum, and small chin. Variable findings are cryptorchidism, hernias, congenital heart defects, and cognitive delay (Elcioglu et al., 2004; Albano et al., 2007). - Genetic Heterogeneity of Omodysplasia In an autosomal dominant form of omodysplasia (OMOD2; 164745), abnormalities are limited to the upper limbs. The facial changes and typical growth defect of the distal humerus with complex deformity of the elbows appear to be similar in both entities (Baxova et al., 1994).;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the glypican 6 gene (GPC6, 604404.0001);

Prefixed ID : #258315;
