Notes

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

J:103841

Linkage analysis was performed on 513 animals from a (SM/J x NZB/BlNJ)F2 intercross to identify QTL affecting obesity traits. Animals were placed on an atherogenic diet for 16 weeks before phenotyping. Parental strain SM/J exhibits smaller body size but higher adiposity compared to parental strain NZB/BlNJ.

Obq21 maps to 54 cM on mouse Chromosome 18 near D18Mit4 (LOD=2.5) with a 95% confidence interval spanning approximately 22 cM - 56 cM. NZB/BlNJ-derived alleles at Obq21 confer increased retroperitoneal fat pad weight with a dominant mode of inheritance.
