Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 3P and 5B. PM1PP3BP6BS2

The NM_004006.3(DMD):c.10211A>G(p.Asp3404Gly) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000207 in 1,205,433 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 9 hemizygotes in GnomAD. In-silico tool predicts a pathogenic 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. D3404E) 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 -2 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 2 benign, 11 uncertain in NM_004006.3

PP3

MetaRNN computational evidence supports a deleterious effect, 0.827

BP6

Variant X-31178681-T-C is Benign according to our data. Variant chrX-31178681-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 567418.

BS2

High AC in GnomAdExome4 at 23 XL,AD gene.
