Is CFH p.Val17Gly (c.50T>G) pathogenic?

CFH p.Val17Gly (c.50T>G) is classified Uncertain significance in CFH (ClinVar, Multiple submitters, 2 submitters; last evaluated 2026-09-17). AlphaMissense: likely benign (0.1153); Absent from gnomAD v4.1; Associated with complement factor H deficiency.

What condition is associated with CFH p.Val17Gly (c.50T>G)?

CFH p.Val17Gly (c.50T>G) is associated with complement factor H deficiency (ClinVar).

How common is CFH p.Val17Gly (c.50T>G) in the general population?

CFH p.Val17Gly (c.50T>G) is absent from gnomAD v4.1 (gnomAD).

How is Immunodeficiency with factor H anomaly inherited?

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

What do computational predictors say about CFH p.Val17Gly (c.50T>G)?

AlphaMissense predicts likely benign (score 0.1153) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.
