Genetic susceptibility to primary sclerosing cholangitis is associated with several different HLA haplotypes, though a single "shared" susceptibility allele has yet to be identified. Most recently, attention has focussed on the MICA alleles in close proximity to the HLA class I, B locus. However, although there are strong associations with MICA*008, implicating this or a closely linked allele as major risk factors, this explanation alone does not account for all of the MHC-encoded susceptibility and resistance to PSC. The present study re-examines HLA class II associations in a large single centre series of well-characterised PSC patients. The specific aims of the study were to test existing associations and to develop hypotheses which together may account for all, or the majority, of the MHC-encoded susceptibility in PSC.
