Abstract

Some patients prescribed flucloxacillin (~ 0.01%) develop drug‐induced liver injury (DILI). HLA‐B*57:01 is an established genetic risk factor for flucloxacillin DILI. To consolidate this finding, identify additional genetic factors, and assess relevance of risk factors for flucloxacillin DILI in relation to DILI due to other penicillins, we performed a genomewide association study involving 197 flucloxacillin DILI cases and 6,835 controls. We imputed single‐nucleotide polymorphism and human leukocyte antigen (HLA) genotypes. HLA‐B*57:01 was the major risk factor (allelic odds ratio (OR) = 36.62; P = 2.67 × 10−97). HLA‐B*57:03 also showed an association (OR = 79.21; P = 1.2 × 10−6). Within the HLA‐B protein sequence, imputation showed valine97, common to HLA‐B*57:01 and HLA‐B*57:03, had the largest effect (OR = 38.1; P = 9.7 × 10−97). We found no HLA‐B*57 association with DILI due to other isoxazolyl penicillins (n = 6) or amoxicillin (n = 15) and no significant non‐HLA signals for any penicillin‐related DILI.
