Is GLIS2 p.Pro85= (c.255A>G) pathogenic?

GLIS2 p.Pro85= (c.255A>G) is classified Likely benign in GLIS2 (ClinVar, Single submitter, 1 submitter; last evaluated 2023-07-07). Very rare (popmax 8.48e-05%, nfe); Associated with nephronophthisis.

What condition is associated with GLIS2 p.Pro85= (c.255A>G)?

GLIS2 p.Pro85= (c.255A>G) is associated with nephronophthisis (ClinVar).

How common is GLIS2 p.Pro85= (c.255A>G) in the general population?

GLIS2 p.Pro85= (c.255A>G) is very rare (popmax 8.48e-05%, nfe) (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.
