Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV005238456 SCV005886212 pathogenic Qualitative or quantitative defects of dystrophin 2025-02-07 criteria provided, single submitter clinical testing Variant summary: The variant involves the duplication of exons 18-30 in the DMD gene. A presumed nomenclature of c.(2168+1_2169-1)_(4233+1_4234-1)dup has been designated for the purposes of this classification. It is assumed to be a tandem duplication in direct orientation (PMIDs: 25640679, 30054569). This Copy Number Variant (CNV) is expected to alter the reading frame and predicted to result in a truncation or absence of the encoded protein due to nonsense mediated decay (NMD). The variant was absent in 16120 control chromosomes. c.(2168+1_2169-1)_(4233+1_4234-1)dup has been reported in the literature in individuals affected with Duchenne Muscular Dystrophy or Becker Muscular Dystrophy (e.g. Wojtal_2015, Ma_2018). These data indicate that the variant is likely associated with disease. The following publications have been ascertained in the context of this evaluation (PMID: 26686765, 29973226). ClinVar contains an entry for this variant (Variation ID: 1067795). Based on the evidence outlined above, the variant was classified as pathogenic.
