Is ENG p.Ile575Met (c.1725C>G) pathogenic?

ENG p.Ile575Met (c.1725C>G) is classified Uncertain significance in ENG (ClinVar, Multiple submitters, 2 submitters; last evaluated 2025-12-29). AlphaMissense: likely benign (0.1173); Very rare (popmax 0.000254%, nfe); Associated with hereditary hemorrhagic telangiectasia.

What condition is associated with ENG p.Ile575Met (c.1725C>G)?

ENG p.Ile575Met (c.1725C>G) is associated with hereditary hemorrhagic telangiectasia (ClinVar).

How common is ENG p.Ile575Met (c.1725C>G) in the general population?

ENG p.Ile575Met (c.1725C>G) is very rare (popmax 0.000254%, nfe) (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.Ile575Met (c.1725C>G)?

AlphaMissense predicts likely benign (score 0.1173) — an in-silico prediction, not a clinical call.

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

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

Remaining individuals 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.
