Is ANKS6 p.Ala25Val (c.74C>T) pathogenic?

ANKS6 p.Ala25Val (c.74C>T) is classified Uncertain significance in ANKS6 (ClinVar, Single submitter, 1 submitter; last evaluated 2022-02-18). AlphaMissense: ambiguous (0.3449); Absent from gnomAD v4.1; Associated with nephronophthisis 16.

What condition is associated with ANKS6 p.Ala25Val (c.74C>T)?

ANKS6 p.Ala25Val (c.74C>T) is associated with nephronophthisis 16 (ClinVar).

How common is ANKS6 p.Ala25Val (c.74C>T) in the general population?

ANKS6 p.Ala25Val (c.74C>T) is absent from gnomAD v4.1 (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.Ala25Val (c.74C>T)?

AlphaMissense predicts ambiguous (score 0.3449) — an in-silico prediction, not a clinical call.

No allele count reported in gnomAD v4.1 (AN 994,922). This is missing data, not an absence: the variant may or may not be present in gnomAD. Rarity (ACMG PM2) and BA1/BS1 cannot be assessed for it.
