Mapping and Phenotype information for this QTL, its variants and associated markers

J:66233

QTL effecting body weight, obesity and muscle weight were found on mouse Chromosomes 1, 4, 5, 7, 11, 12, 13, and 17 and for leptin on 14 and insulin on chromosome 4. The cross used in the genome wide scan included approximately 400 F2 mice from a (DU6i xDBA/2)F1 intercross. DU6i is a strain selected for high body weight. 93 microsatellite markers were analyzed in the genome wide scan.

Locations of the QTL were provided by the authors and may not be equivalent to the closest microsatellites. Abdominalfat percent QTL 6 and abdominal fat weight QTL 7 were mapped to mouse chromosome 17 at positions 36 and 39 respectively.

10.03.2014 - Curator Note: We had originally associated the abdominal fat weight QTL 7 identified here, mapping to 39cM on mouse Chr 17, as Afw7. Afw7 was originally mapped using a different cross, an outbred cross of DU6 x DUK, in J:49578 in 1998. We consider the current mapping study a separate mapping experiment and have named the QTL identified here as Afw19.
