Genome-wide analyses identify 60 loci associated with liver triglyceride content.

Genome-wide analysis of 71,488 Europeans uncovers 60 loci linked to liver triglyceride content, including 31 novel variants, with heritability estimated at 25%.

• Why it matters: Understanding genetic factors influencing liver triglyceride levels is crucial for elucidating the biological basis of steatotic liver disease and related metabolic conditions.
• What they did: Researchers conducted a large-scale genome-wide association study meta-analysis using MRI-derived liver triglyceride data, identifying 60 loci and validating 14 of 31 new variants in disease cohorts.
• The result: Higher polygenic risk scores for liver triglyceride content are associated with increased odds of cirrhosis (2.71-fold) and hepatocellular carcinoma (7.47-fold), linking genetic susceptibility to metabolic and inflammatory pathways.
