Abstract

OBJECTIVE: The purpose of this study was to further evaluate the role of low activity MTHFR variants as well as to explore interactive effects between alcoholic drink consumption and MTHFR variants and risk of distal colorectal adenomatous polyps.METHODS: We examined the relationship between MTHFR C677T and A1298C gene polymorphisms and risk of distal adenomas in one of the largest case control studies of 946 polyp-free controls and 894 cases, all participants of the UK Flexible Sigmoidoscopy Screening Trial (UKFSS).RESULTS: Investigation of the effect of the MTHFR C677T polymorphism in this large UKFSS study revealed no overall association on adenoma risk (P>0.05). However the MTHFR 1298C allele was linked, for the first time, to high risk adenomas, although in males only (odds ratio (OR) for A/C+C/C compared with A/A 1.55; 95% confidence interval (CI), 1.08-2.22; P=0.018).CONCLUSIONS: In this, the largest study of these polymorphisms in relation to colorectal adenoma, there was no evidence for an interaction with alcohol in combination with the variant forms of MTHFR (P>0.05).
