Is ENG p.Ala60Asp (c.179C>A) pathogenic?

ENG p.Ala60Asp (c.179C>A) is classified Benign/Likely benign in ENG (ClinVar, Multiple submitters, 3 submitters; last evaluated 2024-11-12). AlphaMissense: likely benign (0.151); Rare (popmax 0.418%, afr); Associated with hereditary hemorrhagic telangiectasia.

What condition is associated with ENG p.Ala60Asp (c.179C>A)?

ENG p.Ala60Asp (c.179C>A) is associated with hereditary hemorrhagic telangiectasia (ClinVar).

How common is ENG p.Ala60Asp (c.179C>A) in the general population?

ENG p.Ala60Asp (c.179C>A) is rare (popmax 0.418%, afr) (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.Ala60Asp (c.179C>A)?

AlphaMissense predicts likely benign (score 0.151) — 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.
