ABCC2 and oculocutaneous albinism type 1: Choong et al. demonstrated a statistically significant association between the wild-type ABCC2 -24C>T CC genotype and an increased risk of acute graft rejection and ATN in a Malaysian KTRs population, compared to individuals carrying variant alleles [11], although other work has shown that Caucasian KTRs showed no association in the number of acute rejections, despite variant carriers of ABCC2 -24C>T showing significantly higher dose-corrected MPA trough levels [12].
