Exon deletion pattern in duchene muscular dystrophy in north west of iran.

ABSTRACT:

Objective

Duchene and Becker Muscular Dystrophy (DMD/ BMD) are x-linked disorders that both are the result of heterogeneous mutations in the dystrophin gene. The frequency and distribution of dystrophin gene deletions in DMD/ BMD patients show different patterns among different populations. This study investigates the deletion rate, type, and distribution of this gene in the Azeri Turk population of North West Iran.

Materials &methods

In this study, 110 patients with DMD/ BMD were studied for intragenic deletions in 24 exons and promoter regions of dystrophin genes by using multiplex PCR.

Results

Deletions were detected in 63 (57.3%) patients, and around 83% localized in the mid-distal hotspot of the gene (on exons 44-52), 21 cases (33.3 %) with single-exon deletions,
