In the field of transplant rejection, identified are SNPs wherein mismatches in variants present in a recipient and donor for such SNPs are predictive of transplant outcome, wherein the SNPs represent non-HLA loci newly implicated in rejection. By the invention, transplant outcomes such as elevated risk of antibody mediated rejection, elevated risk of T-cell mediated rejection, or low risk of rejection can be predicted by analyzing mismatches between donor and recipient for the enumerated SNPs. Certain SNPs enumerated are predictive of kidney transplant outcome. The compatibility of prospective donors can be assessed for a recipient, allowing for optimized donor-recipient pairing.
