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 made for transcript

Verdict is Benign. Variant got -20 ACMG points.

BP4

This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 3 / 10, using the threshold of <=3). The score ranges from 0 to 10, with values ≤3 considered benign and >5 classified as pathogenic. Computational evidence support a benign effect (BayesDel_noAF=-0.71).

BP6

Variant X-31178825-G-A is Benign according to our data. Variant chrX-31178825-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 94423.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chrX-31178825-G-A is described in Lovd as [Benign]. Variant chrX-31178825-G-A is described in Lovd as [Likely_benign].

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00197 (221/112131) while in subpopulation NFE AF= 0.00357 (190/53171). AF 95% confidence interval is 0.00316. There are 0 homozygotes in gnomad4. There are 54 alleles in male gnomad4 subpopulation. Median coverage is 23. This position pass quality control queck.
