Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4BP6BS2_Supporting

The NM_004006.3(DMD):​c.1687C>T​(p.Arg563Cys) variant causes a missense change. The variant allele was found at a frequency of 0.000081 in 1,209,239 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 35 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R563H) has been classified as Likely benign.

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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.287921).
BP6
Variant X-32573762-G-A is Benign according to our data. Variant chrX-32573762-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 289591.
BS2
High AC in GnomAd4 at 12 XL,AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
