Is EMD p.Ser29Leu (c.86C>T) pathogenic?

EMD p.Ser29Leu (c.86C>T) is classified Uncertain significance in EMD (ClinVar, Single submitter, 1 submitter; last evaluated 2023-04-11). AlphaMissense: likely pathogenic (0.7998); Very rare (popmax 0.000112%, nfe); Associated with X-linked Emery-Dreifuss muscular dystrophy.

What condition is associated with EMD p.Ser29Leu (c.86C>T)?

EMD p.Ser29Leu (c.86C>T) is associated with X-linked Emery-Dreifuss muscular dystrophy (ClinVar).

How common is EMD p.Ser29Leu (c.86C>T) in the general population?

EMD p.Ser29Leu (c.86C>T) is very rare (popmax 0.000112%, nfe) (gnomAD).

How is Emery-Dreifuss muscular dystrophy inherited?

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

What do computational predictors say about EMD p.Ser29Leu (c.86C>T)?

AlphaMissense predicts likely pathogenic (score 0.7998) — an in-silico prediction, not a clinical call.

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.
