However, single nucleotide polymorphism (SNP) is one of many mechanisms that leads to increased risk for type 2 diabetes. To locate genes and loci that are responsible for the risk of type 2 diabetes, genome wide association studies (GWAS) was utilized to compare the genomes of diabetic patient group and the non-diabetic control group.

Maturity-onset diabetes of the young (MODY) refers to any of several hereditary forms of diabetes mellitus caused by mutations in an autosomal dominant gene disrupting insulin production. [1] Along with neonatal diabetes , MODY is a form of the conditions known as monogenic diabetes.
The PPARGC1A gene regulates genes involved in energy metabolism. [1] [2] Since type 2 diabetes is characterized by chronic hyperglycaemia as a result of impaired pancreatic beta cell function [3] and insulin resistance in peripheral tissues, [4] it was thought that the gene might be downregulated in type 2 diabetes patients through DNA methylation.
The thrifty gene hypothesis, or Gianfranco's hypothesis [citation needed] is an attempt by geneticist James V. Neel to explain why certain populations and subpopulations in the modern day are prone to diabetes mellitus type 2. He proposed the hypothesis in 1962 to resolve a fundamental problem: diabetes is clearly a very harmful medical ...
Mutations of the gene for this enzyme can cause unusual forms of diabetes or hypoglycemia. Glucokinase (GK) is a hexokinase isozyme , related homologously to at least three other hexokinases. [ 4 ] All of the hexokinases can mediate phosphorylation of glucose to glucose-6-phosphate (G6P), which is the first step of both glycogen synthesis and ...
Diabetes mellitus can be experimentally induced in vivo for research purposes by streptozotocin [34] or alloxan, [35] which are specifically toxic to beta cells. Mouse and rat models of diabetes also exist including ob/ob and db/db mice which are a type 2 diabetes model, and non-obese diabetic mice (NOD) which are a model for type 1 diabetes. [36]
Type 2 diabetes (T2D), formerly known as adult-onset diabetes, is a form of diabetes mellitus that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. [6] Common symptoms include increased thirst , frequent urination , fatigue and unexplained weight loss . [ 3 ]
The diabetes that accompanies the hearing loss can be similar to Type 1 diabetes or Type 2 diabetes; however, Type 1-like diabetes is the more common form of the two. MIDD has also been associated with a number of other issues including kidney dysfunction, gastrointestinal problems , and cardiomyopathy .
