Abstract
Diabetes is a hyperglycemic condition caused due to irregular insulin secretion by the beta cells of pancreatic islets. Among types of diabetes, type 2 diabetes mellitus is mainly due to genetic causes. Transport of glucose is major concern in this disease but there is not much research on the glucose transporters. The aim of study was the investigation of genetic variation in gene SLC2A2 responsible for regulation of insulin secretion. Samples of diabetic patients and control group (healthy individuals) were collected from Multan. DNA extraction kit was used for extraction of DNA. Exon 1 amplification of SLC2A2 gene was done by the standard and gradient PCR. Sequencing and further purification procedures were performed by 1st base laboratory, Singapore. Codon Code Aligner was used for the molecular analysis and the sequence alignment of the results was done using software named MEGA6. Results showed the presence of one heterozygous loci at position no. 3995 of gene. This T/G heterozygous loci was observed among diabetic patients. Results conclude that presence of heterozygous position in SLC2A2 gene has association with the high body weight among obese diabetic patients.
