Is DMD p.Arg1968Ser (c.5904A>T) pathogenic?

DMD p.Arg1968Ser (c.5904A>T) is classified Uncertain significance in DMD (ClinVar, Single submitter, 1 submitter; last evaluated 2024-05-14). AlphaMissense: likely pathogenic (0.8643); Absent from gnomAD v4.1; Associated with Becker muscular dystrophy.

What condition is associated with DMD p.Arg1968Ser (c.5904A>T)?

DMD p.Arg1968Ser (c.5904A>T) is associated with Becker muscular dystrophy, dilated cardiomyopathy 3B, Duchenne muscular dystrophy (ClinVar).

How common is DMD p.Arg1968Ser (c.5904A>T) in the general population?

DMD p.Arg1968Ser (c.5904A>T) 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.Arg1968Ser (c.5904A>T)?

AlphaMissense predicts likely pathogenic (score 0.8643) — an in-silico prediction, not a clinical call.
