Description : Primary biliary cirrhosis-1 (PBC1) is significantly associated with SNPs at the IL12A
locus (161560) on chromosome 3p12-q13.2. Significant association of PBC has also been
shown with SNPs at the HLA-DQB1 locus (604305) on chromosome 6p21.3 (PBC2; 613007),
at the IL12RB2 locus (601642) on chromosome 1p31.2 (PBC3; 613008), at the IRF5 (607218)-TNPO3
(610032) locus on chromosome 7q32 (PBC4; 614220), and at the ZPBP2 locus (608499)
on chromosome 17q12-q21 (PBC5; 614221). Primary biliary cirrhosis (PBC) is a chronic,
progressive cholestatic liver disease that usually affects middle-aged women and eventually
leads to liver failure (Kaplan, 1996). See also Reynolds syndrome (613471), in which
primary biliary cirrhosis is a feature.;
