Is DTYMK p.Leu8Phe (c.22C>T) pathogenic?

DTYMK p.Leu8Phe (c.22C>T) is classified Uncertain significance in DTYMK (ClinVar, Single submitter, 1 submitter; last evaluated 2025-04-18). AlphaMissense: likely benign (0.1327); Very rare (popmax 0.00146%, afr).

How common is DTYMK p.Leu8Phe (c.22C>T) in the general population?

DTYMK p.Leu8Phe (c.22C>T) is very rare (popmax 0.00146%, afr) (gnomAD).

What do computational predictors say about DTYMK p.Leu8Phe (c.22C>T)?

AlphaMissense predicts likely benign (score 0.1327) — an in-silico prediction, not a clinical call.

AlphaMissense	0.1327	likely benign
REVEL	0.704	pathogenic-leaning
SaProt	LLR -7.34	tolerated
⇒ REVEL calls this damaging; AlphaMissense and SaProt do not.

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.
