Is DMD p.Arg2202= (c.6606A>G) pathogenic?

DMD p.Arg2202= (c.6606A>G) is classified Likely benign in DMD (ClinVar, Single submitter, 1 submitter; last evaluated 2023-10-18). Very rare (popmax 0.000112%, nfe); Associated with Duchenne muscular dystrophy.

What condition is associated with DMD p.Arg2202= (c.6606A>G)?

DMD p.Arg2202= (c.6606A>G) is associated with Duchenne muscular dystrophy (ClinVar).

How common is DMD p.Arg2202= (c.6606A>G) in the general population?

DMD p.Arg2202= (c.6606A>G) is very rare (popmax 0.000112%, nfe) (gnomAD).

How is Duchenne muscular dystrophy inherited?

Typically X-linked recessive (Orphanet). A genetic counselor can assess individual risk for a family.

Population frequency

Grpmax group 0.000112% European (non-Finnish) · 1/894,779 alleles

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
