Genetic loci have also been linked to leptin production in mice (Chr 3 (143.2 MB), 10 (107.1 MB), 12 (100.6 MB) [7], 7 (~ 100 MB) [8] 14 (37–73 MB) [9], 2 (141.1 MB), 17 (40.2 MB) [10], 5 (93.3 MB), 12 (100.6 MB), 15 (55.3 MB) [11]) and such models may provide further useful information on the genetic structure of diabetes and its physiological construction. Here, LEP is linked to diabetes mellitus.
