Genetics of Autoimmune Hepatitis

Briefly noted:

Recently, the first genome-wide association identified mutations associated with type 1 autoimmune hepatitis (AIH1) (Gastroenterol 2014; 147: 443-52).

Cohort: 649 Dutch adults with AIH1 and 13,436 controls

Findings: prominent association with rs2187668 (associated with variants in the major histocompatibility complex region) and with variants of SH2B3 (rs3184504) and CARD10 (rs6000782)

Interpretation (from authors): “These findings support a complex genetic basis for AIH pathogenesis and indicate that part of the genetic susceptibility overlaps with that for other immune-mediated liver diseases.”
