Langer mesomelic dysplasia (LMD) is characterized by severe limb aplasia or severe hypoplasia of the ulna and fibula, and a thickened and curved radius and tibia. These changes can result in displacement deformities of the hands and feet. Hypoplasia of the mandible is also observed (Langer, 1967). See also Leri-Weill dyschondrosteosis (127300), a less severe phenotype that results from heterozygous defect in the SHOX or SHOXY genes. [from OMIM]
