McKusick's type of metaphyseal chondrodysplasia
Formerly called cartilage-hair hypoplasia. A syndrome of short-limbed dwarfism, leg bowing, and a variety of other skeletal features: fine sparse hair, eyebrows and eyelashes; hypoplasia of the cartilage, laxity of the ligaments, short hands and feet, and immunological incompetence. The syndrome was first recognized among the Amish, but has more recently been identified in other groups. Inheritance is autosomal recessive, with reduced penetrance.
