Hirsutism–skeletal dysplasia–mental retardation syndrome with abnormal face and a uric acid metabolism disorder

Abstract
We report on a German boy, born to nonconsanguineous parents, with an apparently new combination of multiple congenital anomalies including extraordinary hirsutism, marked brachycephaly, abnormal position of thumbs, pedes excavati with claw-toes, an abnormal face, and mental retardation. Additionally the boy manifests a disorder of uric acid metabolism. This sporadic case may represent a new syndrome due to a fresh autosomal or X-linked mutation, or chance-isolated case due to segregation of an autosomal recessive gene.
