How common is RECQL p.Ser142Phe (c.425C>T) in the general population?

RECQL p.Ser142Phe (c.425C>T) is very rare (popmax 8.67e-05%, nfe) (gnomAD).

What do computational predictors say about RECQL p.Ser142Phe (c.425C>T)?

AlphaMissense predicts likely pathogenic (score 0.98) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.98	likely pathogenic · top 10% in RECQL
REVEL	0.574	indeterminate
SaProt	LLR -14.16	damaging
⇒ AlphaMissense and SaProt both call this damaging; REVEL is indeterminate.

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

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

Population frequency

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.
