Variant description

• Allele Type: QTL
• Mutation: Undefined
• Mutation details: The C57BL/6J allele at this locus is recessive to the 129P2/OlaHsd regarding its effect on intestinal adenoma number when inherited in conjunction with Apc^Min. 15 of 144 known genes located within this QTL region are polymorphic between 129P2/OlaHsd and C57BL/6J. (J:152194)
• Inheritance: Recessive

Notes

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

J:152194

A Genetic linkage experiment was carried out to determine if there was a genetic modifier affected the number of intestinal tumors in Apc(min/+) mice. 129P2/OlaHsd (- /Erb) knockout mice were backcrossed to C57BL/6J - Apc(Min/+) mice for 10 generations (N10). At both N5 and N10 Erb(+/-) females were intercrossed with Apc(Min/+) males. Using STS markers linkage was analyzed at N5 whereby 10 of the intercross mice with the fewest intestinal adenomas were mated to 10 with the most intestinal adenomas. A more robust explanation of the linkage cross is reported in the methods section for this cross. The 1.5 LOD support interval ranges from D5Mit48 to D5Mit388 with a peak at D5Mit348. The QTL in this region is defined as Mom5 with Rint1 suggested as a strong candidate
