We report our detailed investigation of a 7-1/2-year-old girl with short stature, aged appearance, decreased subcutaneous fat and muscle mass, dry coarse hair, foot deformities, macroepiphyses with prominent but lax joints, and osteoporosis with recurrent fractures who is the off-spring of first cousins. This constellation of abnormalities differs from previously reported cases where macroepiphyses were a prominent finding. Our patient appears, therefore, to have a new, autosomal recessively inherited, syndrome.
