Apparently normal at birth, he did not walk until 17 months of age, and he never ran normally. By age 3, toe-walking and a waddling gait were evident, and he had difficulty climbing stairs and rising from a chair without using his arms. His stance was described as broad based, with a forward pelvic tilt and compensatory lumbar lordosis. By age 12, there was obvious scoliosis, which became progressively severe after he was confined to a wheelchair. He is an only child. His parents are neurologically asymptomatic, but a maternal uncle died in his mid-20s of a progressive neuromuscular disorder.
