Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_004006.3(DMD):c.10141C>T(p.Arg3381Ter) variant causes a stop gained change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. R3381R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 14, 2024 | This sequence change creates a premature translational stop signal (p.Arg3381*) in the DMD gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DMD are known to be pathogenic (PMID: 16770791, 25007885). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individuals with DMD-related muscular dystrophy (PMID: 8281150, 10320864, 27593222). ClinVar contains an entry for this variant (Variation ID: 11273). For these reasons, this variant has been classified as Pathogenic. - |
