DIAGNOSIS OF DUCHENNE CARRIERS USING MOLECULAR GENETICS TECHNIQUE
Main Article Content
Abstract
Duchenne muscular dystrophy (DMD) is the most common inherited neuromuscular disease in the muscular dystrophy pathology’s group. This recessive genetic disease is linked to the chromosome X, therefore the diagnosis of the pathologic gene’s carriers for female members in the family of DMD patients play important role in the genetic counseling before birth. This also allows early detections of fetuses in case the pregnant women are at risk. Ojectives: To apply whole genome sequencing (WGS) and MLPA technique in the diagnosis of DMD carriers for 85 females in DMD families. Methods and Subjects: Cross sectional, descriptive study. WGS was performed to confirm the carriers of point mutations on Dystrophine gene, MLPA technique was performed to confirm the carriers of duplication, deletion mutations on Dystrophine gene for females. Results: 52 female members are carriers, accounting for 61%; 33 females do not carry pathologic genes, accounting for 39%. Conclusions: MLPA and WGS could be applied successfully in the diagnosis of DMD carriers in current era.
