Amoxicillin-clavulanate (AC) is aleading cause of idiosyncratic DILI, but little is understood about genetic susceptibilityto this adverse reaction.Methods: We performed a genome-wide association study using 822,927 singlenucleotide polymorphism (SNP) markers from 201 White European and US cases of ACDILI and 532 population controls, matched for genetic background. AB Results: AC-DILI was associated with many loci in the major histocompatibilitycomplex. The strongest effect was with a human leukocyte antigen (HLA) class II SNP(rs9274407, P=4.8×10−14), which correlated with rs3135388, a tag SNP of HLADRB1*1501-DQB1*0602 that was previously associated with AC-DILI. Conditioned onrs3135388, rs9274407 is still significant (P=1.1×10−4). An independent association wasobserved in the class I region (rs2523822, P=1.8×10−10), related to HLA-A*0201. Themost significant class I and II SNPs showed statistical interaction (P=0.0015). Highresolution HLA genotyping (177 cases and 219 controls) confirmed associations of HLAA*0201 (P=2×10−6) and HLA-DQB1*0602 (P=5×10−10), and their interaction(P=0.005). Additional, population-dependent effects were observed in HLA alleles withnominal significance. In an analysis of auto-immunerelated genes, rs2476601 in the genePTPN22 was associated (P=1.3×10−4). AB Conclusions: Class I and II HLA genotypes affect susceptibility to AC-DILI, indicatingthe importance of the adaptive immune response in pathogenesis. The HLA genotypesidentified will be useful in studies of the pathogenesis of AC-DILI, but have limited utilityas predictive or diagnostic biomarkers because of the low positive-predictive values PB Elsevier YR 2011 FD 2011-07 LK https://hdl.handle.net/10630/40269 UL https://hdl.handle.net/10630/40269 LA eng NO Lucena MI, Molokhia M, Shen Y, Urban TJ, Aithal GP, Andrade RJ, Day CP, Ruiz-Cabello F, Donaldson PT, Stephens C, Pirmohamed M, Romero-Gomez M, Navarro JM, Fontana RJ, Miller M, Groome M, Bondon-Guitton E, Conforti A, Stricker BHC, Carvajal A, Ibanez L, Yue QY, Eichelbaum M, Floratos A, Pe'er I, Daly MJ, Goldstein DB, Dillon JF, Nelson MR, Watkins PB, Daly AK; Spanish DILI Registry; EUDRAGENE; DILIN; DILIGEN; International SAEC.
