FCGR3A and post-transplant lymphoproliferative disease: Our observation that solid organ transplant recipients with PTLD carrying a FcγRIIIA p.158V allele more often had triple immunosuppression including low-dose steroids compared to individuals with a FcγRIIIA p.158F homozygote (i.e., low-affinity) genotype might help to explain the distribution difference.
