Association of the HLA locus and TNF with type I autoimmune hepatitis susceptibility in New Zealand Caucasians.


ABSTRACT: PURPOSE:The precise etiology of autoimmune hepatitis (AIH) remains unknown, although a number of genetic loci have been implicated in the susceptibility of type 1 AIH. The purpose of this study was to test for association of these loci with type 1 AIH in New Zealand Caucasians. METHODS:77 AIH patients and 485 healthy controls were genotyped for the SNPs rs2187668 (HLA-DRB*03:01), rs660895 (HLA-DRB*04:01), rs3749971 (HLA-A1-B8-DR3), rs231775 (CLTLA4), rs1800629 (TNF), and rs1800682 (FAS) using predesigned TaqMan SNP genotyping assays. Chi square analysis was used to test for association of allele and genotype with overall AIH, and with severe fibrosis and ALT levels at 6 months. RESULTS:Significant risk of AIH was conferred by the minor alleles of rs2187668 (OR?=?2.45, 95% CI 1.65-3.61, p?
