Is DMD p.Lys697Asn (c.2091G>T) pathogenic?

DMD p.Lys697Asn (c.2091G>T) is classified Uncertain significance in DMD (ClinVar, Single submitter, 1 submitter; last evaluated 2024-12-17). AlphaMissense: likely pathogenic (0.6118); Very rare (popmax 0.000112%, nfe); Associated with Duchenne muscular dystrophy.

What condition is associated with DMD p.Lys697Asn (c.2091G>T)?

DMD p.Lys697Asn (c.2091G>T) is associated with Duchenne muscular dystrophy (ClinVar).

How common is DMD p.Lys697Asn (c.2091G>T) in the general population?

DMD p.Lys697Asn (c.2091G>T) is very rare (popmax 0.000112%, 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.Lys697Asn (c.2091G>T)?

AlphaMissense predicts likely pathogenic (score 0.6118) — an in-silico prediction, not a clinical call.

European (non-Finnish)grpmax	0.000112%	894,262

Ashkenazi Jewish shows a higher raw frequency than the grpmax group above it. gnomAD excludes bottlenecked groups — Finnish, Ashkenazi Jewish, Amish and “Remaining individuals” — from grpmax, because founder effects make their frequencies unrepresentative for filtering. The table is sorted by frequency, so an excluded group can sit above the grpmax row.

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.
