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.

The c.344A>T (p.N115I) alteration is located in exon 3 (coding exon 3) of the CFHR2 gene. This alteration results from a A to T substitution at nucleotide position 344, causing the asparagine (N) at amino acid position 115 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
