Is DMD p.Arg1842Thr (c.5525G>C) pathogenic?

DMD p.Arg1842Thr (c.5525G>C) is classified Uncertain significance in DMD (ClinVar, Multiple submitters, 3 submitters; last evaluated 2024-06-17). AlphaMissense: likely benign (0.1269); Very rare (popmax 0.00235%, nfe); Associated with Duchenne muscular dystrophy.

What condition is associated with DMD p.Arg1842Thr (c.5525G>C)?

DMD p.Arg1842Thr (c.5525G>C) is associated with Duchenne muscular dystrophy, cardiomyopathy, Becker muscular dystrophy (ClinVar).

How common is DMD p.Arg1842Thr (c.5525G>C) in the general population?

DMD p.Arg1842Thr (c.5525G>C) is very rare (popmax 0.00235%, nfe) (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.Arg1842Thr (c.5525G>C)?

AlphaMissense predicts likely benign (score 0.1269) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

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.
