HUS1 and anemia: A recent study by Woillard et al in 189 renal transplant adults treated with enteric-coated mycophenolic acid, in whom 15 SNPs were studied (in IMPDH1, IMPDH2, ABCC2, SLCO1B3, CYP2C8, HUS1, UGT1A8, UGT1A9, UGT2B27, IL12A), the variant allele UGT2B7 (840 G>A rs7438135) was associated with an increased risk of anemia (GG vs. AA HR 1.8 [95% CI 1.23–2.88], p = 0.0034).
