Purpose:
To determine correlation between genetic susceptibility of type 2 diabetes mellitus (T2DM) and Src homology 2 B adapter protein 1 (SH2B1) gene polymorphism in a diabetic population. Methods: A total of 111 T2DM patients (DM group) and 34 healthy controls (NC group) from Shanxi Provincial People's Hospital were included in this study. Exon 9 of the SH2B1 gene was detected using the Sanger sequencing method, and the relationship between SH2B1 gene polymorphism and diabetes was analyzed. Results: Comparison of the data between the two groups showed that the values of TG, the updated HOMA of insulin resistance (HOMA2-IR), weight, body mass index, waist circumference, fasting blood glucose and fasting insulin levels of the DM group were higher than those of the NC group (P < 0.05). The HOMA2 insulin sensitivity (%S) of the DM group was lower than that of the NC group (P < 0.05). Sequencing analysis revealed that the following five single nucleotide polymorphisms in exon 9 of SH2B1 may be related to T2DM: rs181578610, rs550079240, chr16.28884655, chr16.28884659 and chr16.28884831. Among them, chr16.28884655 was found to be significantly related to diabetes; this site, located on the NM_015503 exon, was related to TG, LDL-C and waist circumference.
Conclusion:
The SH2B1 gene locus chr16.28884655 was found to be significantly related to genetic susceptibility to T2DM.

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
