What condition is associated with INVS p.Pro769= (c.2307G>A)?

INVS p.Pro769= (c.2307G>A) is associated with nephronophthisis 2, nephronophthisis (ClinVar).

How common is INVS p.Pro769= (c.2307G>A) in the general population?

INVS p.Pro769= (c.2307G>A) is ultra-rare (popmax 0.011%, 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.
