Overview


Hajdu-Cheney syndrome is a rare connective tissue disorder characterized by acroosteolysis (the breakdown of the bones in the fingers and the toes), skull deformities, and generalized osteoporosis.[1][2] Other symptoms may include short stature, joint laxity, premature loss of teeth, hearing loss, and a hoarse voice. Most patients have normal intelligence.[1][3] This condition is inherited in an autosomal dominant fashion and caused by mutations in the NOTCH2 gene.[4]
