Genes affected
DMD (HGNC:2928): (dystrophin) This gene spans a genomic range of greater than 2 Mb and encodes a large protein containing an N-terminal actin-binding domain and multiple spectrin repeats. The encoded protein forms a component of the dystrophin-glycoprotein complex (DGC), which bridges the inner cytoskeleton and the extracellular matrix. Deletions, duplications, and point mutations at this gene locus may cause Duchenne muscular dystrophy (DMD), Becker muscular dystrophy (BMD), or cardiomyopathy. Alternative promoter usage and alternative splicing result in numerous distinct transcript variants and protein isoforms for this gene. [provided by RefSeq, Dec 2016]

Duchenne muscular dystrophy Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 11, 2017 | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in DMD are known to be pathogenic (PMID: 16770791, 25007885). This variant has not been reported in the literature in individuals with DMD-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Ser599Valfs*8) in the DMD gene. It is expected to result in an absent or disrupted protein product. - |
