A 4-year-old boy presents to your clinic for evaluation of 'clumsiness.' His parents state that he began walking at 30 months of age. They note that he is not able to keep up with his peers in athletic activities. He is unable to climb steps without the aid of a handrail. On exam, he stands with increased lumbar lordosis and a wide based stance. When asked to rise from a seated position on the floor, the child first rolls into a crawling position on all four limbs, stands up by extending his knees and uses his upper extremities bracing against his thighs to help elevate his trunk. You confirm the diagnosis with serum enzyme assay followed by DNA analysis. The parents ask you what the chances are of their child passing on this genetic disease to his male offspring.
