Has a duchenne muscular dystrophy chromosome map been done yet?

Genetics: The molecular biology of dmd has been fairly well investigated at this time. The gene responsible for the disease codes for a mutated form of the protein called dystrophin. This gene is located on the x-chromosome. For more information on this go to http://www.Ncbi.Nlm.Nih.Gov/pubmedhealth/pmh0001724/.

A single gene : Disorder, dmd is caused by a mutation in the x-linked dmd gene, xp21.1, causing absence of dystrophin, a muscle protein. Deletions in a specific part of the dystrophin gene are associated with cognitive impairment, especially in verbal memory & auditory comprehension. There's also some increased risk of adhd & autistic disorder. See www.Ncbi.Nlm.Nih.Gov/omim, online mendelian inheritance in man.
