Is DNHD1 p.Asp622Ala (c.1865A>C) pathogenic?

DNHD1 p.Asp622Ala (c.1865A>C) is classified Benign in DNHD1 (ClinVar, Multiple submitters, 3 submitters; last evaluated 2019-03-14). AlphaMissense: likely benign (0.0591); Common (popmax 87.4%, eas) — too common for a highly-penetrant pathogenic allele.

What do computational predictors say about DNHD1 p.Asp622Ala (c.1865A>C)?

AlphaMissense predicts likely benign (score 0.0591) — 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.
