Duchenne Muscular Dystrophy (DMD)(Include picture of someone with disorder here)


Chromosome and Gene Information


DMD is located on the 23rd chromosome and is an X linked recessive disorder.(Include picture of the 23 chromosomes here, point out the 23rd)




Since DMD is X linked recessive, a man can't pass it on to his son, but he will pass it on to his daughter. A carrier woman has a 25% chance of having an affected son or a carrier daughter.(Include

picture of pedigree here)


Males with DMD usually pass away by their early 20s. A smaller percent doesn't even make it to their late teens, and even less make it to their 30s. At an average age of 9, DMD is accompanied with occasional use of a wheelchair, and total reliance usually follows by early teens.


Discovery and Research


French neurologist, Dr. Guillaume-Benjamin-Amand Duchenne, was not the first to describe this form of muscular dystrophy, but he was the first to study the diseased muscles microscopically.

To do this, he invented a tool that removed small portions of tissue located inside the body.


By developing this tool, called Duchenne's trocar, he founded the diagnostic practice of biopsy. After this, he created a complete account of the clinical features and progression of DMD.(Include picture of...
