Is ANKS6 p.Ile375= (c.1125T>C) pathogenic?

ANKS6 p.Ile375= (c.1125T>C) is classified Benign/Likely benign in ANKS6 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2025-12-13). Rare (popmax 0.815%, sas); Associated with nephronophthisis 16.

What condition is associated with ANKS6 p.Ile375= (c.1125T>C)?

ANKS6 p.Ile375= (c.1125T>C) is associated with nephronophthisis 16 (ClinVar).

How common is ANKS6 p.Ile375= (c.1125T>C) in the general population?

ANKS6 p.Ile375= (c.1125T>C) is rare (popmax 0.815%, sas) (gnomAD).

How is Nephronophthisis inherited?

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

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.
