Insulin-induced gene 2 (INSIG2) and its homolog INSIG1 encode closely related endoplasmic reticulumproteins that regulate the proteolytic activation of sterol regulatory elementbinding proteins, transcription factors that activate the synthesis of cholesterol and fatty acids in animal cells. Several studies have been carried out to identify INSIG2 genetic variants associated with metabolic dise...

The INSIG2 (INSIG2 is primarily involved in the regulation of fatty acid and cholesterol synthesis) gene is suggested to be obesity related. An INSIG2 promoter variant, G-102A, has been detected and was demonstrated to be of potential functional significance. In two cohorts of middle-aged men, the association between this v...

BACKGROUND The INSIG2 gene has been implicated in cholesterol metabolism and a single nucleotide polymorphism (SNP) near INSIG2 has been shown to be associated with obesity. We sought to determine the relationship of the INSIG2 SNP to cardiovascular disease (CVD) related phenotypes. METHODS AND RESULTS Nine hundred forty six patients undergoing percutaneous coronary intervention (PCI) in wave...

BACKGROUND Dyslipidemia and overweight are common issues in children. Identifying genetic markers of risk could lead to targeted interventions. A polymorphism of SNP rs7566605 near insulin-induced gene 2 (INSIG2) has been identified as a strong candidate gene for obesity, through its feedback control of lipid synthesis. OBJECTIVE To identify polymorphisms in INSIG2 which are associated with o...

BACKGROUND In a whole-genome scan, a single nucleotide polymorphism (SNP) (rs7566605) upstream of the insulin-induced gene 2 (INSIG2) was shown to influence body mass index and obesity in the Framingham Heart Study, with replication of these results in an additional 4 of 5 studies. However, other studies could not replicate the association. Because INSIG2 plays an important role in cholesterol ...

Background Obesity is a very common disorder resulting from an imbalance between food intake and energy expenditure, and it has a substantial impact on the development of chronic diseases. The aim of this study was to examine the association of INSIG2 (rs7566605) gene polymorphism with obesity and obesity associated phenotypes in North Indian subjects. Methods The variants were investigated ...

A genome-wide association study showed that the tagging single nucleotide polymorphism (SNP) rs7566605 in the insulin-induced gene 2 (INSIG2) was associated with obesity. Attempts to replicate this result in different populations have produced inconsistent findings. We aimed to study the association between the rs7566605 SNP with obesity and other metabolic parameters in Malaysian Malays. Anthr...

Background: Obesity is a very common disorder resulting from an imbalance between food intake and energy expenditure, and it has a substantial impact on the development of chronic diseases.  The aim of this study was to examine the association of INSIG2 (rs7566605) gene polymorphism with obesity and obesity associated phenotypes in North Indian subjects. Methods: The variants were investig...

Background. Insulin induced gene 2 (INSIG2) encodes a protein that has a biological effect on regulation of adipocyte metabolism and body weight. This study aimed to investigate the association of INSIG2 gene -102G>A polymorphism with obesity related phenotypes in Chinese children and test gender-specific effects. Methods. The 2,030 independent individuals aged from 7 to 18 years, including 705...

Heritability studies have estimated the genetically attributable part of body mass index variance to be in the range of 30-70 %. Rs7566650 (G>C) single-nucleotide polymorphism (SNP) near the promoter of the INSIG2 gene has been identified as associated with body mass index. The gene product of INSIG2 is involved in regulation of fatty acid and cholesterol synthesis. In order to replicate this a...
