Core Tip

Core tip: Our study demonstrated that non-alcoholic fatty liver disease (NAFLD) patients with TT genotype of C (-159) T polymorphism in cluster of differentiation 14 promoter gene have a higher risk of NAFLD development. However, this polymorphism did not affect liver disease severity. We found no association of toll-like receptor (TLR) 2 ARG753, TLR4 (Asp299Gly), TLR4 (Thr399Ile), and CD 14 C/T 550 polymorphisms with the risk of NAFLD development.
