The Nmur2 gene is located in a suggestive obesity QTL on chromosome 11, distal to the diabetes QTL Nidd3. Neuromedin U exerts an anorexigenic effect on meal frequency that is blunted in NZO as compared with lean C57BL/6J mice (15 vs. 60 % reduction in C57BL/6J). Here, NMUR2 is linked to obesity disorder.
