Association studies of novel obesity-related gene variants with quantitative metabolic phenotypes in a population-based sample of 6,039 Danish individuals

AssociationN=6,039Burgdorf KS et al.(2012)· Diabetologia

This association study investigates 18 BMI-associated and 14 WHR-associated gene variants identified by prior GWAS in 6,039 Danish individuals from the Inter99 cohort. The study found that QPCTL rs2287019 C allele was associated with increased insulinogenic index (7.4%, p=4.0×10⁻⁷) and disposition index (5.6%, p=6.4×10⁻⁵), while LRP1B rs2890652 C allele was associated with insulin resistance (3.3% increase in HOMA-IR, p=0.0011). For WHR variants, LYPLAL1/SLC30A10 rs4846567 G allele carriers showed improved insulin sensitivity (5.2% lower HOMA-IR in women, p=0.00086), whereas VEGFA rs6905288 A allele carriers showed insulin resistance in women (3.7% increase in HOMA-IR, p=0.00036).

About NISCH

This gene encodes a nonadrenergic imidazoline-1 receptor protein that localizes to the cytosol and anchors to the inner layer of the plasma membrane. The orthologous mouse protein has been shown to influence cytoskeletal organization and cell migration by binding to alpha-5-beta-1 integrin. In humans, this protein has been shown to bind to the adapter insulin receptor substrate 4 (IRS4) to mediate translocation of alpha-5 integrin from the cell membrane to endosomes. Expression of this protein was reduced in human breast cancers while its overexpression reduced tumor growth and metastasis; possibly by limiting the expression of alpha-5 integrin. In human cardiac tissue, this gene was found to affect cell growth and death while in neural tissue it affected neuronal growth and differentiation. Alternative splicing results in multiple transcript variants encoding differerent isoforms. Some isoforms lack the expected C-terminal domains of a functional imidazoline receptor.
