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

J:68441

Authors indicated that enhanced growth rate in C57BL/6J-Cish2^hg/Cish2^hg mice may be modulated by other genes associated with growth. 1132 F2 mice from a cross between (C57BL/6J-Cish2^hg/Cish2^hg X CAST/EiJ)F1's yielded 274 +/+ , 596 hg/+ and 262 hg/hg mice with the hg/hg used in a genome wide scan to find QTLs associated with growth rates. A total of 15 QTLs were mapped. QTLs for total weight gain (wg1 - wg4) mapped to mouse Chromosomes 2, 8, and 11, with wg1 and wg2 mapping to mouse chromosome 2.QTLS for total carcass protein (Carp1-Carp3) mapped to Chromosomes 2, 11 and 17. QTLs for total carcass ash weight (Cara1-Cara3) mapped to mouse Chromosomes 2, 11 and 17. QTLs for percent carcass fat (Carf1 and Carf2) mapped to mouse Chromosomes 5 and 9 and QTLS for femur length (Feml1-Feml3) mapped to mouse chromosomes 2, 9, and 17.
