In the past decade, progress in the field of complex disease genetics has been accelerated by the HapMap project (http://hapmap. ncbi. nlm. nih. gov/), which led to the development of dense genotyping arrays, and by the availability of large DNA repositories of patients created by dedicated investigators. Such resources have led to the discovery of novel susceptibility loci of human disease by means of genome-wide association studies (GWAS). These ‘‘a priori studies’’(a shift from the traditional approach of hypothesis-specific research) have allowed an unbiased method to decipher the genetic architecture of liver disorders. In this issue of Seminars in Liver Disease, a group of experts:(1) summarizes the findings of recent genetic studies, including GWAS, in different liver diseases;(2) examines the scientific and clinical ramifications of these observations; and (3) proposes future methodological approaches to better delineate the genetic contribution in liver diseases. We are indebted to our contributors for superb reviews on the assigned topics. Mark Thursz and colleagues have written a synopsis on ‘‘Understanding the Host Genetics of Chronic Hepatitis B and C.’’Traditional therapies for viral hepatitides have focused on the infectious agent. The recent identification of the IL-28B genotype as a major determinant of host treatment response and spontaneous resolution of infection of patients with hepatitis C virus is the best example of how genetic discoveries can revolutionize clinical practice. Christopher Day and colleagues have contributed a review on ‘‘Genetics of Alcoholic and Nonalcoholic Fatty Liver Disease.’’Susceptibility and modifier genes of both entities are discussed, including genetic loci that participate in disease progression from steatohepatitis to fibrosis and to hepatocellular cancer. Gideon Hirschfield and Pietro Invernizzi provide an overview on ‘‘Progress in the Genetics of Primary Biliary Cirrhosis.’’Two recent GWAS, as well as notable candidate gene studies, are reviewed and related to the pathogenesis of primary biliary cirrhosis with suggestions on future studies to better delineate this disorder. Frank Lammert and colleagues present an update on ‘‘Dissecting the Genetic Heterogeneity of Gallbladder Stone Formation.’’Improving the understanding of subgroups of patients with gallstone disease could have significant clinical impact. Susceptibility genes for gallstones are discussed along with ramifications of these observations on patient counseling. Jean-Charles Nault and Jessica Zucman-Rossi give an overview on ‘‘Genetics of Hepatobiliary Carcinogenesis.’’Malignancy is a dreaded complication of advanced liver disease. Molecular pathways of carcinogenesis in both hepatocellular carcinoma and cholangiocarcinoma are discussed along with the promise of targeted therapies. Tom Hemming Karlsen and Arthur Kaser contribute a review on ‘‘Deciphering the Genetic Predisposition to Primary Sclerosing Cholangitis.’’To date, the pathobiology of primary sclerosing cholangitis remains elusive. Functional annotations of the current disease loci are presented in an organized fashion as well as the challenges of translating these findings into clinical practice. Aftab Ala and Michael Schilsky have written a review on ‘‘Genetic Modifiers of Liver Injury in Hereditary Liver Disease.’’This challenging topic covers Wilson disease, hereditary hemochromatosis, and a-1 anti-trypsin deficiency, and underscores the influence of genetics on disease variability as observed in the clinic. Finally, Brian Juran and Konstantinos Lazaridis provide a conceptual framework on ‘‘Genomics in the Post-GWAS Era.’’The authors describe the lessons learned from the …
