Is KANK4 p.Pro286Ser (c.856C>T) pathogenic?

KANK4 p.Pro286Ser (c.856C>T) is classified Uncertain significance in KANK4 (ClinVar, Single submitter, 1 submitter; last evaluated 2022-09-15). AlphaMissense: likely benign (0.1082); Very rare (popmax 0.00534%, afr).

How common is KANK4 p.Pro286Ser (c.856C>T) in the general population?

KANK4 p.Pro286Ser (c.856C>T) is very rare (popmax 0.00534%, afr) (gnomAD).

What do computational predictors say about KANK4 p.Pro286Ser (c.856C>T)?

AlphaMissense predicts likely benign (score 0.1082) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1082	likely benign
REVEL	0.113	moderately benign-leaning
SaProt	LLR -8.23	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.
Splicing

Overall

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.
