Graft-versus-host disease (GVHD) remains one of the major complications of hematopoietic stem cell transplantation (HSCT). Several etiological factors were investigated. Among these, vitamin D and hence its receptor (VDR) gene polymorphisms have gained much interest; however, the results are still controversial. Using PCR-RFLP, we genotyped VDR polymorphisms FokI (rs10735810), ApaI (rs7975232), and Taq1 (rs731236) in 80 patient/donor pairs according to DNA availability. No association was encountered between VDR polymorphisms and GVHD. Neither was there any impact on survival. Only grade II-IV acute GVHD was associated with inferior overall (pā€‰=ā€‰.01), but not disease-free survival. The controversy between our results and the literature may be attributed to marked variability in the relative distribution of VDR genotypes in different populations. Also different environmental factors, including exposure to sun, may ensure vitamin D sufficiency nullifying the impact of VDR polymorphisms.
