As a result, patients with TGFB1 IP haplotypes were less likely to be affected by AR in CsA arm (IP vs. HP: OR  = 0.57, 95% CI, 0.34–0.94), which could be interpreted as a clue that the recipients with TGFB1 IP haplotypes can benefit from CsA after organ transplantation. This evidence concerns the gene TGFB1 and incontinentia pigmenti.
