[5] The patient was homozygous for the H3 haplotype, which comprises three non-pathogenic SNPs in the CFH gene that are associated with predisposition to atypical HUS: (i) c.1–332 C > T in the promoter; (ii) a silent mutation at Q672, and (iii) a E936D substitution. Here, CFH is linked to atypical hemolytic-uremic syndrome.
