Abstract

The invention discloses a method for predicting the risk of non-alcoholic fatty liver disease by genetic polymorphism. According to the method, the risk of NAFLD in the population can be predicted. Based on the comparative analysis of genetic data of a large number of NAFLD population and healthy population in China, three polymorphic sites of TM6SF2 rs58542926, PNPLA3 rs738409 and TRBI rs17321515closely related to NAFLD susceptibility are selected, and the data are statistically analyzed to calculate the risk of NAFLD susceptibility genotype in Chinese population. The method has important guiding significance for prevention and treatment of the NAFLD, and is suitable for popularization and application.

Description

technical field [0001] The present invention relates to the field of prediction of human non-alcoholic fatty liver, more specifically, relates to a method for predicting the risk of non-alcoholic fatty liver by gene polymorphism. Background technique [0002] Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease that affects both adults and children around the world. NAFLD can progress from a benign histologic disease stage characterized by pure fat accumulation (commonly referred to as simple steatosis or nonalcoholic fatty liver disease) to a more severe histologic form characterized by hepatocellular injury, mixed inflammatory lobular infiltrates, and Characterized by nonalcoholic steatohepatitis (NASH). Similar to other chronic liver diseases, both NAFLD and NASH can lead to the progression of fibrosis in some patients, and eventually develop into liver cirrhosis and its complications. Due to the late economic development in Asia, most patients have a sh...
