Answer

The incidence of MD varies, depending on the specific type of MD under consideration. Duchenne MD is the most common MD and is sex-linked, with an inheritance pattern of 1 case per 3500 live male births. [13, 14] One third of cases occurs as a result of spontaneous new mutations. [15]  Becker MD is the second most common form, with an incidence of 1 case per 30,000 live male births. [16] Other types of MD are rare. For example, limb-girdle dystrophy occurs in only 1.3% of patients with MDs.
