Is ANKS6 p.Pro599Ser (c.1795C>T) pathogenic?

ANKS6 p.Pro599Ser (c.1795C>T) is classified Uncertain significance in ANKS6 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-02-07). AlphaMissense: likely benign (0.0629); Very rare (popmax 8.55e-05%, nfe); Associated with nephronophthisis 16.

What condition is associated with ANKS6 p.Pro599Ser (c.1795C>T)?

ANKS6 p.Pro599Ser (c.1795C>T) is associated with nephronophthisis 16 (ClinVar).

How common is ANKS6 p.Pro599Ser (c.1795C>T) in the general population?

ANKS6 p.Pro599Ser (c.1795C>T) is very rare (popmax 8.55e-05%, nfe) (gnomAD).

How is Nephronophthisis inherited?

Typically Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about ANKS6 p.Pro599Ser (c.1795C>T)?

AlphaMissense predicts likely benign (score 0.0629) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.0629	likely benign
REVEL	0.036	moderately benign-leaning
SaProt	LLR -5.39	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.
