In this paper, the study aimed to analyze the sequence and structure of Transcription Factor 7 Like 2 gene (TCF7L2) in Iraqi Diabetic Mellitus Type II (T2DM) Patients and was compared with standard sequence form National Center of Bioinformatics Tools (NCBI) using BLAST. Ten blood samples of (T2DM) Iraqi patients, was collected from Al-Mustansiriya University National Diabetes Centre in Baghdad Province/Iraq (17-65 year). DNA was extracted from whole blood of patients’ samples using the Quick-DNA™ Blood MiniPrep kit, then it was sent to Korea at Macrogen Corporartion Company, where they used automated DNA sequencing for sequence analysis. The results of the sequence analysis of (T2DM) patients’ samples, we found: six missense mutations, one deletion mutation, and three silent mutations detected using BLAST in (NCBI). All mutations appeared at the same sites of the gene which controls the rate of genetic information transcription that indicates to have a relationship with (T2DM). These mutations were recorded on the (NCBI). The physicochemical properties of (TCF7L2) determined in the present study included; alpha-helical structure and 3-Dimension structure appeared contrast when compared with the gene template. Briefly, mutations effected (TCF7L2) which influences the structure, physicochemical properties of the protein, and the secretion of insulin hormone which maintains glucose level in blood.
