Is ANKS6 p.Pro564Ser (c.1690C>T) pathogenic?

ANKS6 p.Pro564Ser (c.1690C>T) is classified Uncertain significance in ANKS6 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-01-05). AlphaMissense: ambiguous (0.5296); Very rare (popmax 0.00409%, afr); Associated with nephronophthisis 16.

What condition is associated with ANKS6 p.Pro564Ser (c.1690C>T)?

ANKS6 p.Pro564Ser (c.1690C>T) is associated with nephronophthisis 16 (ClinVar).

How common is ANKS6 p.Pro564Ser (c.1690C>T) in the general population?

ANKS6 p.Pro564Ser (c.1690C>T) is very rare (popmax 0.00409%, afr) (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.Pro564Ser (c.1690C>T)?

AlphaMissense predicts ambiguous (score 0.5296) — an in-silico prediction, not a clinical call.

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.
