ABSTRACT
<p><b>OBJECTIVE</b>To optimize the methods for genetic detection and prenatal diagnosis of Duchenne muscular dystrophy (DMD).</p><p><b>METHODS</b>Denaturing high-performance liquid chromatography (DHPLC), multiplex PCR (mPCR), sequencing and other molecular techniques were used in combination for molecular diagnosis of 8 cases diagnosed as DMD.</p><p><b>RESULTS</b>Among the 8 cases, 4 have carried large deletions, 3 have point mutations, among which 6 were of de novo type. Prenatal diagnosis were offered for 5 families, the results showed that none of the fetuses had carried large deletions or point mutations. The pregnancies had continued and healthy babies were born.</p><p><b>CONCLUSION</b>Combined use of short tandem repeat, DHPLC, mPCR and sequencing can improve the detection of DMD gene mutations. By establishing and optimizing genetic and prenatal diagnostic methods, accurate genetic counseling can be provided for families affected with DMD.</p>
