CC       associated with variants affecting the gene represented in this entry.
CC   -!- DISEASE: Metaphyseal anadysplasia 2 (MANDP2) [MIM:613073]: A bone
CC       development disorder characterized by skeletal anomalies that resolve
CC       spontaneously with age. Clinical characteristics are evident from the
CC       first months of life and include slight shortness of stature and a mild
CC       varus deformity of the legs. Patients attain a normal stature in
CC       adolescence and show improvement or complete resolution of varus
CC       deformity of the legs and rhizomelic micromelia.
