Figure 2 Serial photographs of patient III‐24 taken between 1976 and 2005. (A) This picture, taken in 1976 (at age 23), shows pes cavus and toe clawing, but preservation of leg musculature. (B,C) Eight years later, incipient bilateral peroneal muscular atrophy is seen. (D,E) At age 38, marked and bilateral leg muscle atrophy is evident. (F) At age 53, wide‐based stance is observed, which is possible only with support; lower limb amyotrophy and foot deformities are now masked by weight gain.
