Phenotype of patient #13. A picture of the feet (a; age 34) shows unequal length of toes. An X-ray image of the right hand (b; age 19) shows an exostosis of the distal radius (arrow) and a shortened ulna. The X-ray of the pelvis (c; age 6) exhibits multiple exostoses on the pelvis and on the proximal femurs, which cause a locally irregular, tubercular aspect of the bone surface (arrows; compare the indicated regions with the contralateral side). The X-ray of the right knee (d; age 6) shows an osteochondroma on the head of the fibula (arrow). The X-ray of the left knee (e; age 6) demonstrates a prominent exostosis on the medial part of the femur (arrow). The X-ray of the lower legs (f; age 7) shows an osteochondroma at the distal end of the left fibula
