People who are affected by<unk>  suffer from three main symptoms: # Dysplasia (improper formation) of the bony components of the elbow # Abnormal shape of carpal bones # Brachydactyly, a symptom where the fingers and toes are shorter than normal. Phenotype People with<unk>  have normal overall body structure. Their morphological differences are in both of their distal humeri, elbows, hands and wrists. The elbows are enlarged with abnormally large olecranons and radial heads. Patients have relatively fixed elbow positions and are therefore unable to pronate or supinate their forearms. Their wrists are also limited in their active movements and have very prominent ulnar sides of the joints. The fingers adopt toe-like structures. Brachydactyly and camptodactyly occur; fingers are short and abnormally bent. These changes in finger shape result in small club shaped appendages. Motion is reduced in all digital joints of the hand.
