Is DES p.Glu461Lys (c.1381G>A) pathogenic?

DES p.Glu461Lys (c.1381G>A) is classified Uncertain significance in DES (ClinVar, Single submitter, 1 submitter; last evaluated 2025-05-12). AlphaMissense: likely pathogenic (0.7643); Absent from gnomAD v4.1; Associated with myofibrillar myopathy 1.

What condition is associated with DES p.Glu461Lys (c.1381G>A)?

DES p.Glu461Lys (c.1381G>A) is associated with myofibrillar myopathy 1 (ClinVar).

How common is DES p.Glu461Lys (c.1381G>A) in the general population?

DES p.Glu461Lys (c.1381G>A) is absent from gnomAD v4.1 (gnomAD).

How is Desminopathy inherited?

Typically Autosomal dominant, Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about DES p.Glu461Lys (c.1381G>A)?

AlphaMissense predicts likely pathogenic (score 0.7643) — an in-silico prediction, not a clinical call.

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

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