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.

Obq20 maps to 0 cM on mouse Chromosome 8 near D8Mit155 (LOD=3.2) with a 95% confidence interval spanning approximately 0 cM - 20 cM. NZB/BlNJ-derived alleles at Obq20 confer increased inguinal and gonadal fat pad weights with an additive mode of inheritance.
