Is CFH p.His537Gln (c.1611T>A) pathogenic?

CFH p.His537Gln (c.1611T>A) is classified Uncertain significance in CFH (ClinVar, Single submitter, 1 submitter; last evaluated 2025-10-02). AlphaMissense: likely benign (0.1118); Absent from gnomAD v4.1; Associated with atypical hemolytic-uremic syndrome.

What condition is associated with CFH p.His537Gln (c.1611T>A)?

CFH p.His537Gln (c.1611T>A) is associated with atypical hemolytic-uremic syndrome, basal laminar drusen, complement factor H deficiency (ClinVar).

How common is CFH p.His537Gln (c.1611T>A) in the general population?

CFH p.His537Gln (c.1611T>A) is absent from gnomAD v4.1 (gnomAD).

How is Atypical hemolytic uremic syndrome 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.His537Gln (c.1611T>A)?

AlphaMissense predicts likely benign (score 0.1118) — 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.
