What condition is associated with DMD p.Arg470= (c.1410A>G)?

DMD p.Arg470= (c.1410A>G) is associated with Duchenne muscular dystrophy, cardiomyopathy, Becker muscular dystrophy (ClinVar).

How common is DMD p.Arg470= (c.1410A>G) in the general population?

DMD p.Arg470= (c.1410A>G) is very rare (popmax 0.00879%, sas) (gnomAD).

How is Duchenne muscular dystrophy inherited?

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

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.
