Is ENG p.Gly4Ser (c.10G>A) pathogenic?

ENG p.Gly4Ser (c.10G>A) is classified Conflicting classifications of pathogenicity in ENG (ClinVar, Conflicting submitters, 2 submitters; last evaluated 2026-04-21). AlphaMissense: likely benign (0.0815); Very rare (popmax 0.00343%, sas); Associated with hereditary hemorrhagic telangiectasia.

What condition is associated with ENG p.Gly4Ser (c.10G>A)?

ENG p.Gly4Ser (c.10G>A) is associated with hereditary hemorrhagic telangiectasia (ClinVar).

How common is ENG p.Gly4Ser (c.10G>A) in the general population?

ENG p.Gly4Ser (c.10G>A) is very rare (popmax 0.00343%, sas) (gnomAD).

How is Hereditary hemorrhagic telangiectasia inherited?

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

What do computational predictors say about ENG p.Gly4Ser (c.10G>A)?

AlphaMissense predicts likely benign (score 0.0815) — 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.
