What causes muscular dystrophy to run in families?

It's in the genes! Many muscular dystrophies are caused by a defect in the genes. These defects are passed on to our children. Some are dominant meaning there is a 50/50 chance of passing it along, others are linked to gender or are recessive meaning you have to reproduce with someone with the same defect to have a child who is affected.

DMD is caused by. mutation of Xp21.2-p21.1, a large gene that encodes dystrophin, a muscle protein. Deletions in specific areas of the gene are associated with cognitive impairment, verbal memory, auditory comprehension, increased risk of ADHD & Autistic Spectrum Disorder.
