Gracile bone dysplasia (GCLEB; MIM 602361) and Kenny-Caffey syndrome, type 2 (KCS2; MIM 127000) are autosomal dominant disorders caused by mutations in the FAM111A gene. They share clinical features such as short stature, thin long bones, primary hypoparathyroidism, hypocalcemia, microphthalmia, triangular face and frontal bossing. Radiographs show increased bone density with small and slender bones.read more
