Duchenne Muscular Dystrophy is a condition which causes muscle weakness. Body cannot make muscle protein called dystrophin making muscles weak and they gradually break down.The muscles becomes weaker as the boys gets older.
DMD only affects boys though girls can be carrier. DMD is inherited condition women with an abnormal gene are carriers and can pass this on to their children but 1/3 of these mutations happens spontaneously.
DMD is suspected in boys who are late in walking, has difficulty in climbing stairs, walks in tip-toes and uses hand to get up from sitting position(Gower sign), calf may look bulky.
DMD is diagnosed by checking the muscle enzyme called CPK in blood which is very high, disease is then confirmed using genetic test.
Many researches are currently undergoing and we hope to find cure for DMD in near future.
