Loss of the tRNALys CUU encoding gene, Chr-11 tRNA-Lys-CUU, is not associated with Type 2 diabetes mellitus

Abstract

Aim: To investigate the presence/absence of the Chr-11 tRNA-Lys-CUU gene as a marker for genetic predisposition to Type 2 diabetes mellitus (T2DM). Methods: We enrolled 122 patients diagnosed with T2DM and 77 non-diabetic individuals. We evaluated clinical and biochemical parameters (body mass index, hypertension, cholesterol levels, glycosylated hemoglobin, triglycerides, etc.), and performed a genotypic profiling of Chr-11 tRNA-Lys-CUU by polymerase chain reaction analyses. Results: Approximately one third of the population lacked Chr-11 tRNA-Lys-CUU. We did not observe a statistically significant association between the presence/absence of Chr-11 tRNA-Lys-CUU and T2DM. Conclusion: The genotypic distribution of Chr-11 tRNA-Lys-CUU in our population was consistent to that reported by others. This gene failed as a marker for T2DM predisposition.
