The Impact of Complement Factor H-Related Protein Gene Deletions on Kidney Transplantation.

ABSTRACT: We recently reported that a homozygous deletion in the complement factor H-related (CFHR) locus predisposed kidney transplant patients to rejection. As donors carried intact genes, the susceptibility may have resulted from an alloimmune reaction to FHR proteins. However, we found no evidence for an anti-FH response. It is therefore possible that CFHR deletions as such affect the rejection risk. Here, we used MLPA and WGS to fine-map and sequence the CFHR region in rs7542235-GG patients, a SNP tagging for ΔCFHR3-1 deletion. Our results confirmed that all patients with this SNP harboured deletions of various sizes encompassing CFHR1. Furthermore, patients with homozygous ΔCFHR3-1 were homozygous for rs6677604-A, a SNP tagging for deletions of CFHR3-1 locus, confirming that allele A tags for
