Long-term observation of a patient with dominant omodysplasia

We report on the natural history of a female with dominant omodysplasia, a rare osteochondrodysplasia with short stature, rhizomelia of the extremities (upper extremities more affected), and short first metacarpals. The proband had normal molecular analysis of the glypican 6 gene (GPC6), which was recently reported as a candidate for autosomal recessive omodysplasia. The findings in this patient were compared to other known and suspected cases of autosomal dominant omodysplasia. Mild rhizomelic shortening of the lower extremities has not been previously reported.
