Is CFH p.Phe614Ser (c.1841T>C) pathogenic?

CFH p.Phe614Ser (c.1841T>C) is classified Uncertain significance in CFH (ClinVar, Single submitter, 1 submitter; last evaluated 2025-10-02). AlphaMissense: likely pathogenic (0.6528); Absent from gnomAD v4.1; Associated with atypical hemolytic-uremic syndrome.

What condition is associated with CFH p.Phe614Ser (c.1841T>C)?

CFH p.Phe614Ser (c.1841T>C) is associated with atypical hemolytic-uremic syndrome, basal laminar drusen, complement factor H deficiency (ClinVar).

How common is CFH p.Phe614Ser (c.1841T>C) in the general population?

CFH p.Phe614Ser (c.1841T>C) 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.Phe614Ser (c.1841T>C)?

AlphaMissense predicts likely pathogenic (score 0.6528) — an in-silico prediction, not a clinical call.
