What condition is associated with ANKS6 p.Ile781= (c.2343C>T)?

ANKS6 p.Ile781= (c.2343C>T) is associated with nephronophthisis 16 (ClinVar).

How common is ANKS6 p.Ile781= (c.2343C>T) in the general population?

ANKS6 p.Ile781= (c.2343C>T) is rare (popmax 0.163%, afr) (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.
