With the widespread implementation of HBV vaccination and the availability of highly effective antiviral therapies, the incidence of metabolic dysfunction-associated steatotic liver disease (MASLD)-related HCC has proportionally increased. Notably, up to 20%–30% of MASLD–related HCC cases develop in the absence of overt cirrhosis. Several genetic variants, primarily in genes related to lipid metabolism, play a key role in HCC development in individuals with MASLD and alcohol-related liver disease. Among these, the rs738409 C&gt;G polymorphism (I148M) in the <i>patatin-like phospholipase domain-containing protein 3</i> (<i>PNPLA3</i>) gene is the strongest genetic factor predisposing to the entire spectrum of MASLD conditions, including cirrhosis and HCC. Importantly, combining <i>PNPLA3</i> I148M with multiple genetic variants robustly associated with progressive liver disease (i.e., polygenic risk scores) improves risk stratification and prediction of HCC in at-risk individuals compared to the single variant alone. In this review, we will discuss the latest evidence on the epidemiology of HCC and the contribution of <i>PNPLA3</i> and <i>PNPLA3</i>-based polygenic risk scores to the development of HCC in at-risk individuals.</p>","PeriodicalId":18101,"journal":{"name":"Liver International","volume":"45 4","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/liv.70051","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
