Furthermore, another gene, GRIN2A, that is part of the family of genes {GRIN1, GRIN2A, GRIN2B, GRIN2C, GRIN2D, GRIN3A, and GRIN3B}, which encode proteins that form a receptor in charge of sending chemical messages between neurons in the brain, was found to be associated to obesity in adult women defined as metabolically healthy in Schlauch et. This evidence concerns the gene GRIN2D and obesity disorder.
