Is ANKS6 p.Pro189Ala (c.565C>G) pathogenic?

ANKS6 p.Pro189Ala (c.565C>G) is classified Conflicting classifications of pathogenicity in ANKS6 (ClinVar, Conflicting submitters, 3 submitters; last evaluated 2024-12-27). AlphaMissense: likely benign (0.0677); Rare (popmax 0.179%, afr); Associated with nephronophthisis 16.

What condition is associated with ANKS6 p.Pro189Ala (c.565C>G)?

ANKS6 p.Pro189Ala (c.565C>G) is associated with nephronophthisis 16 (ClinVar).

How common is ANKS6 p.Pro189Ala (c.565C>G) in the general population?

ANKS6 p.Pro189Ala (c.565C>G) is rare (popmax 0.179%, 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.Pro189Ala (c.565C>G)?

AlphaMissense predicts likely benign (score 0.0677) — 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.
