Test Details: DMD is a rapidly progressive form of muscular dystrophy that occurs exclusively in males. It is caused by an alteration (mutation) in a gene, called the dystrophin gene, that can be inherited in families in an X-linked recessive pattern. DMD has early onset affecting children between age 2 and 6 years and causes progressive degeneration of voluntary muscles with terminal involvement of cardiac and respiratory muscles. Multiplex DNA PCR is used for mutation analysis of the Dystrophin gene. It indicated for rapid preliminary screening of individuals with clinical features suggestive of muscular dystrophy.
