The authors also suggest that BAF155 plays important roles in ubiquitin‐independent degradation of HBx, which might be related to the pathogenesis and carcinogenesis of HBV‐associated HCC.105 Studies focused on understanding the contributions of BAF60a and BAF155 to HCC, and how these factors interact with other SWI/SNF‐related subunits should be conducted. The gene discussed is SMARCD1; the disease is hepatocellular carcinoma.
