Is DPCD p.Leu109Ile (c.325C>A) pathogenic?

DPCD p.Leu109Ile (c.325C>A) is classified Uncertain significance in DPCD (ClinVar, Single submitter, 1 submitter; last evaluated 2022-04-25). AlphaMissense: likely benign (0.138); Very rare (popmax 0.00167%, amr).

How common is DPCD p.Leu109Ile (c.325C>A) in the general population?

DPCD p.Leu109Ile (c.325C>A) is very rare (popmax 0.00167%, amr) (gnomAD).

What do computational predictors say about DPCD p.Leu109Ile (c.325C>A)?

AlphaMissense predicts likely benign (score 0.138) — 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.

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.
