Is PGR p.Gln536Pro (c.1607A>C) pathogenic?

PGR p.Gln536Pro (c.1607A>C) is classified Benign in PGR (ClinVar, Multiple submitters, 2 submitters; last evaluated 2018-11-20). AlphaMissense: likely benign (0.0636); Low-frequency (popmax 1.65%, afr).

How common is PGR p.Gln536Pro (c.1607A>C) in the general population?

PGR p.Gln536Pro (c.1607A>C) is low-frequency (popmax 1.65%, afr) (gnomAD).

What do computational predictors say about PGR p.Gln536Pro (c.1607A>C)?

AlphaMissense predicts likely benign (score 0.0636) — 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.
