Is DMD p.Asp2484Asn (c.7450G>A) pathogenic?

DMD p.Asp2484Asn (c.7450G>A) is classified Conflicting classifications of pathogenicity in DMD (ClinVar, Conflicting submitters, 3 submitters; last evaluated 2025-02-02). AlphaMissense: likely benign (0.1339); Very rare (popmax 0.00353%, sas); Associated with Duchenne muscular dystrophy.

What condition is associated with DMD p.Asp2484Asn (c.7450G>A)?

DMD p.Asp2484Asn (c.7450G>A) is associated with Duchenne muscular dystrophy, cardiomyopathy, Becker muscular dystrophy (ClinVar).

How common is DMD p.Asp2484Asn (c.7450G>A) in the general population?

DMD p.Asp2484Asn (c.7450G>A) is very rare (popmax 0.00353%, sas) (gnomAD).

How is Duchenne muscular dystrophy inherited?

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

What do computational predictors say about DMD p.Asp2484Asn (c.7450G>A)?

AlphaMissense predicts likely benign (score 0.1339) — an in-silico prediction, not a clinical call.

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.
