PPARGC1A and liver cancer: In another case–control study [35], the investigators assessed the specific association between liver cancer risk and PPARGC1A polymorphisms in a Moroccan population, confirming that PPARGC1A serves as a common prognostic marker for hepatocellular carcinoma, and that the PPARGC1A rs8192678 polymorphism is strongly associated with an increased risk of hepatocellular carcinoma in the Moroccan population.
