Which chromosome is affected by duchenne muscular dystrophy (dmd)?

X chromosome. The gene for the abnormal protein is located on the x chromosome. Hence it is "x linked" . Mostly boys are affected.
Dystrophin gene. This gene is located on the x chromosome and is recessive. Only males develop the disease, but females can be carriers.

Are there any very mild cases of duchenne muscular dystrophy (dmd)?

DMD vs BMD. Not really. This is a progressive disease with average life expectancy of less than 20 years. Rapidly progressed once in wheel chair due to scoliosis and resultant respiratory issues. A disease called becker's muscular dystrophy is similar with much less symptoms and much longer life expectancy. Read more...

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/. Read more...
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. Read more...

How does duchenne muscular dystrophy affect the body?

See below. It is caused by an alteration (mutation) in a gene, called the dmd gene that can be inherited in families in an x-linked recessive fashion, but it often occurs in people from families without a known family history of the condition. Individuals who have dmd have progressive loss of muscle function and weakness, which begins in the lower limbs. Read more...
