To explore the relationship between AFB1 exposure status and AT3 rs8021276 polymorphism in the risk for liver cirrhosis, we accomplished a joint analysis of AT3 rs8021276 genotypes and AFB1 exposure using individuals with both rs8021276-AA and low level of AFB1 exposure as a reference (OR = 1) (Table 4). Here, ATXN3 is linked to cirrhosis of liver.
