Key Points
This research aims to identify novel genetic drivers of hepatocellular carcinoma (HCC) across different ancestries.
Conducted a meta-analysis involving 15 cohorts with 17,329 HCC cases and 2,424,298 controls.
Identified genome-wide significant loci linked to HCC risk across various ancestries.
Performed transcriptome-wide analysis to assess gene enrichment and genetic architecture.
Discovered 15 germline loci associated with HCC, some novel in/near key genes.
Found significant heterogeneity in genetic risk factors among different ancestries, especially in the HLA locus.
Enrichment analysis highlighted involvement of the beta-catenin pathway in HCC pathogenesis.

Implication
Meta-analysis reveals that genetic variants influence HCC risk in diverse populations, indicating a significant role of the beta-catenin pathway.
