Adip18 exhibits additive inheritance.
Mapping and Phenotype information for this QTL, its variants and associated markersJ:103841Linkage 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. On mouse Chromosome 17, Adip18 maps to 10 cM near D17Mit58 (LOD=2.9) with a 95% confidence interval spanning approximately 0 cM - 18 cM. NZB/BlNJ-derived alleles at Adip18 confer increased inguinal and gonadal fat pad weights with an additive mode of inheritance. Previously identified obesity QTL Afpq6 (36 cM) and Obq4 (4 cM) map near Adip18. Obwq4 maps to 32 cM on mouse Chromosome 17 near D17Mit20 (LOD=6.8) with a 95% confidence interval spanning approximately 20 cM - 44 cM. NZB/BlNJ-derived alleles at Obwq4 confer increased body weight and all fat pad weight with an additive mode of inheritance. Previously identified obesity QTL mapping near Obwq4 include Afpq6 (36 cM), Obq4 (4 cM), Scfq4 (21.9cM), and Epfq4 (17.4 cM). Obwq4 appears central to a network of interacting loci, which involves Bfq1 (81 cM) on mouse Chromosome 2. Tgif is a potential candidate gene for Obwq4. |
