Genes linked to Hemolytic uremic syndrome, atypical, susceptibility to, 1
CFH: Complement factor H
It restrains the alternative complement pathway on host surfaces and in plasma, protecting tissues from uncontrolled complement amplification. Pathogenic variants or risk alleles are associated with atypical hemolytic uremic syndrome, C3 glomerulopathy, and age-related macular degeneration.
1 disease-causing and 5 uncertain variants in CFH are linked to Hemolytic uremic syndrome, atypical, susceptibility to, 1.
Weakly linked (only a few uncertain records): C3.
Known disease-causing variants in Hemolytic uremic syndrome, atypical, susceptibility to, 1
| Variant | Position | Protein part | Clinical label |
|---|---|---|---|
| CFH S1191L | 1191 | Sushi 20 | Disease-causing (★★) |
Same protein, different disease
- Atypical hemolytic-uremic syndrome is also caused by CFH variants; they fall mostly in different places as the Hemolytic uremic syndrome, atypical, susceptibility to, 1 variants (12 disease-causing).
- Factor H deficiency is also caused by CFH variants; they fall mostly in different places as the Hemolytic uremic syndrome, atypical, susceptibility to, 1 variants (4 disease-causing).

About this data
Variant–disease links come from ClinVar, Open Targets and UniProt, pooled from the latest public CATVariant analysis of each human protein. Evidence scores use the ACMG/AMP Bayesian points scale with computable criteria only (position among known disease variants, rarity in gnomAD, calibrated predictors, deep mutational scanning); there is no family or patient data, so they prioritise variants for expert review and never classify them.
