15. Genetic Analysis of Obesity and Non-Insulin-dependent Diabetes Mellitus in KK Mice


The inbred strain KK is one of the most suitable polygenic mouse models for non-insulin dependent diabetes mellitus with moderate obesity. To identify the gene or genes responsible for the diseases, a QTL mapping study was carried out. We identified two QTLs for body weight and obesity on chromosomes 4 and 6.
