Genes affected
CFHR2 (HGNC:4890): (complement factor H related 2) This gene belongs to a family of complement factor H-related genes (CFHR), which are clustered together with complement factor H gene on chromosome 1, and are involved in regulation of complement. Mutations in CFHR genes have been associated with dense deposit disease and atypical haemolytic-uraemic syndrome. Alternatively spliced transcript variants have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2023The c.328G>A (p.V110I) alteration is located in exon 3 (coding exon 3) of the CFHR2 gene. This alteration results from a G to A substitution at nucleotide position 328, causing the valine (V) at amino acid position 110 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
