Invitae | RCV000799430 | SCV000939091 | pathogenic | Duchenne muscular dystrophy | 2019-12-20 | criteria provided, single submitter | clinical testing | This variant is an out-of-frame deletion of the genomic region encompassing exon 45 of the DMD gene. This is expected to create a premature translational stop signal and result in an absent or disrupted protein product. Similar copy number variants have been observed in individuals with Duchenne or Becker muscular dystrophy (PMID: 11257468, 18683213, 25244321, 26081009). Experimental studies have shown that deletion of exon 45 may also disrupt mRNA splicing and cause skipping of exon 44, which results in an in-frame deletion of exons 44-45 (PMID: 9040743, 24871807). For these reasons, this variant has been classified as Pathogenic. |
