Title: The common variant of rs6214 in insulin like growth factor 1 (IGF1) gene: a potential protective factor for non-alcoholic fatty liver disease.
Abstract: PURPOSE: Regarding the central role of insulin resistance in NAFLD, we explored whether insulin-like growth factor 1 (IGF1) and insulin-like growth factor-binding protein 3 (IGFBP3) gene variants were associated with NAFLD susceptibility. METHODS: IGF1 (rs6214) and IGFBP3 (rs3110697) gene variants were genotyped in 154 cases with biopsy-proven NAFLD and 156 controls using PCR-RFLP method. RESULTS: The IGF1 rs6214 "AA + AG" genotype compared with the "GG" genotype appeared to be a marker of decreased NAFLD susceptibility (p = .006; OR = 0.47, 95%CI = 0.28-0.80). Furthermore, the IGF1 rs6214 "A" allele was underrepresented in the cases than controls (p = .024; OR = 0.61, 95%CI = 0.40-0.94). However, we observed no significant difference in genotype or allele frequencies between the cases and controls for IGFBP3 gene. CONCLUSIONS: To our knowledge, these findings suggest, for the first time, that the IGF1 rs6214 "A" allele and "AA + AG" genotype have protective effects for NAFLD susceptibility. Nonetheless, further studies are needed to validate our findings.
