Is CFH p.Glu1145Asp (c.3435G>C) pathogenic?

CFH p.Glu1145Asp (c.3435G>C) is classified Uncertain significance in CFH (ClinVar, Multiple submitters, 2 submitters; last evaluated 2026-09-17). AlphaMissense: likely benign (0.3015); Very rare (popmax 0.00446%, eas); Associated with complement factor H deficiency.

What condition is associated with CFH p.Glu1145Asp (c.3435G>C)?

CFH p.Glu1145Asp (c.3435G>C) is associated with complement factor H deficiency (ClinVar).

How common is CFH p.Glu1145Asp (c.3435G>C) in the general population?

CFH p.Glu1145Asp (c.3435G>C) is very rare (popmax 0.00446%, eas) (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.Glu1145Asp (c.3435G>C)?

AlphaMissense predicts likely benign (score 0.3015) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change

REVEL	0.036	moderately benign-leaning
SaProt	LLR -7.90	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

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.

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.
