Less frequent symptoms include vomiting and belching. Sometimes people with indigestion also experience heartburn, but heartburn and indigestion are two separate conditions. Heartburn is a pain or burning feeling in the center of your chest that may radiate into your neck or back during or after eating.
Because the Duchenne gene is found on the X-chromosome, it primarily affects boys; however, it occurs across all races and cultures. Duchenne results in progressive loss of strength and is caused by a mutation in the gene that encodes for dystrophin.Because dystrophin is absent, the muscle cells are easily damaged.ecause the Duchenne gene is found on the X-chromosome, it primarily affects boys; however, it occurs across all races and cultures.

A number sign (#) is used with this entry because Duchenne muscular dystrophy is caused by mutation in the gene encoding dystrophin (DMD; 300377). Description. Dystrophin-associated muscular dystrophies range from the severe Duchenne muscular dystrophy (DMD) to the milder Becker muscular dystrophy (BMD; 300376).1979) found DMD with X-1 translocation and suggested that the DMD locus is at Xp1106 or Xp2107. A number of females with X-autosome translocations with the breakpoint in the Xp21 band have shown Duchenne muscular dystrophy.
