Is DMD p.His3353Pro (c.10058A>C) pathogenic?

DMD p.His3353Pro (c.10058A>C) is classified Uncertain significance in DMD (ClinVar, Single submitter, 1 submitter; last evaluated 2018-02-22). AlphaMissense: likely benign (0.2342); Absent from gnomAD v4.1; Associated with Becker muscular dystrophy.

What condition is associated with DMD p.His3353Pro (c.10058A>C)?

DMD p.His3353Pro (c.10058A>C) is associated with Becker muscular dystrophy, dilated cardiomyopathy 3B, Duchenne muscular dystrophy (ClinVar).

How common is DMD p.His3353Pro (c.10058A>C) in the general population?

DMD p.His3353Pro (c.10058A>C) is absent from gnomAD v4.1 (gnomAD).

How is Becker 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.His3353Pro (c.10058A>C)?

AlphaMissense predicts likely benign (score 0.2342) — an in-silico prediction, not a clinical call.
