Genes affected

CFHR3 (HGNC:16980): (complement factor H related 3) The protein encoded by this gene is a secreted protein, which belongs to the complement factor H-related protein family. It binds to heparin, and may be involved in complement regulation. Mutations in this gene are associated with decreased risk of age-related macular degeneration, and with an increased risk of atypical hemolytic-uremic syndrome. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

May 24, 2024

The c.202G>A (p.D68N) alteration is located in exon 2 (coding exon 2) of the CFHR3 gene. This alteration results from a G to A substitution at nucleotide position 202, causing the aspartic acid (D) at amino acid position 68 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
