Is GAL p.Arg67Pro (c.200G>C) pathogenic?

GAL p.Arg67Pro (c.200G>C) is classified Uncertain significance in GAL (ClinVar, Single submitter, 1 submitter; last evaluated 2020-05-20). AlphaMissense: likely benign (0.0818); Very rare (popmax 0.00823%, nfe); Associated with familial temporal lobe epilepsy 8.

What condition is associated with GAL p.Arg67Pro (c.200G>C)?

GAL p.Arg67Pro (c.200G>C) is associated with familial temporal lobe epilepsy 8 (ClinVar).

How common is GAL p.Arg67Pro (c.200G>C) in the general population?

GAL p.Arg67Pro (c.200G>C) is very rare (popmax 0.00823%, nfe) (gnomAD).

What do computational predictors say about GAL p.Arg67Pro (c.200G>C)?

AlphaMissense predicts likely benign (score 0.0818) — an in-silico prediction, not a clinical call.

REVEL	0.031	moderately benign-leaning
SaProt	LLR -6.05	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

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.
