Notes

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

J:52089

A QTL affecting alcohol acceptance, Aaq1, was verified in a (C57BL/6J x DBA/2J)F4 population and in a population of genotypically selected animals. Aaq1 maps to mouse chromosome 15 near D15Mit60 at approximately 25 cM.

J:43654

In the present study Aaq1, a QTL linked to alcohol acceptance that was previously mapped to a candidate region on mouse Chromosome 15 using BXD RI strains, was confirmed using a (C57BL/6J x DBA/2J)F2 population. Aaq1 mapped to 15 cM - 48 cM on mouse Chromosome 15 with a peak LOD score of 3.8 at approximately 30 cM. C57BL/6J-derived alleles confer increased alcohol acceptance in a dominant fashion at Aaq1. A potential candidate gene for Aaq1 is the peripheral benzodiazepine receptor gene, Bzrp.
