The expression of the nearby genes mediated only the association between cg06500161 (ABCG1) and cg20544516 (SREBF1) and FLI.<h4>Conclusions</h4>Our findings highlight the association between the methylation levels of cg06690548 (SLC7A11) and liver steatosis, describe the dynamic relationship between whole blood DNA methylation and MASLD, and contribute to a deeper understanding of the pathophysiology of liver diseases. The gene discussed is ABCG1; the disease is liver disorder.
