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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2023The c.161A>G (p.Y54C) alteration is located in exon 2 (coding exon 2) of the CFHR3 gene. This alteration results from a A to G substitution at nucleotide position 161, causing the tyrosine (Y) at amino acid position 54 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
