These findings suggest focal abnormal brain development that was milder than that reported in Duchenne muscular dystrophy, which may in part reflect the reduced and mosaic expression of dystrophin due to X-chromosome inactivation.<h4>Conclusion</h4>The neuropathological findings in this case and in previous studies of Duchenne muscular dystrophy partially overlap with those of schizophrenia. This evidence concerns the gene DMD and Duchenne muscular dystrophy.
