QTL Reference Notes

The Collaborative Cross (CC) is a large (~1,000 line) panel of recombinant inbred (RI) mouse strains being developed through a community effort (Churchill et al. 2004). The CC combines the genomes of eight genetically diverse founder strains - A/J, C57BL/6J, 129S1/SvImJ, NOD/ShiLtJ, NZO/HlLtJ, CAST/EiJ, PWK/PhJ, and WSB/EiJ - to capture nearly 90% of the known variation present in laboratory mice. CC strains are derived using a unique funnel breeding scheme. Once inbred, the RI CC lines can be used to generate thousands of potential 'outbred' but completely reproducible genomes through the generation of recombinant inbred crosses (RIX). The designation 'PreCC' is used to describe a mapping population of CC mice that is still at incipient stages of inbreeding. CTC (2004), Churchill, G. A., et al.. The Collaborative Cross, a community resource for the genetic analysis of complex traits. Nat Genet. 36, 1133-7.

A total of 102 reproductive, behavioral, physiological, and morphological

traits were subject to QTL mapping in a set of 414 lines of PreCC#/Unc mice.

Phenotyping and genotyping were performed in at least one breeding pair per line from generations G2:F5G2:F8 for QTL analysis. Most of the genotyped mice came from the G2:F5 generation. From this generation, 235 lines were tested. Approximately 7500 mice of both sexes (except for gonadal fat-pad mass and testes weight) from up to 626 lines were phenotyped for body weight, tail length, fasting plasma glucose level, weights of kidney and heart, and behavioral and physiological traits; of these, about 3000 have been phenotyped for adiposity based on perigonadal fat-pad weight. Of the total number of mice phenotyped, 52% were females and 48% were males.

A custom array using the Illumina iSelect platform for the Infinium system was developed for SNP genotyping. A subset of 11,969 SNPs were chosen from the NIEHS-Perlegen combined SNP panel. A sliding window was used to search for the minimumsized sets of SNPs that could discern all eight progenitor strains. Once a set of SNPs was identified that together could discriminate all eight founder haplotypes within the window or the window length reached 1.86 Mb, the search was terminated and a new window was started. The resulting array enabled genotyping at more than 1200 windows within which the haplotypes from the progenitor strains could be identified.

Several of the traits measured were highly correlated, including 50 sleep-related

parameters and several similar blood measures. Approximately 72

unique though not statistically independent phenotypes were

considered. Among these, eight statistically significant (p < 0.05)

main-effect QTL were detected using a single-locus mapping approach: red cell distribution width, hotplate latency, average percent of sleep time in the dark, distance traveled in open field during the first 3 min, periosteal circumference

of the femur, peak activity onset after sleep deprivation, body

length, and cumulative distance from the center of the open field.

An additional nine suggestive QTL were detected (p < 0.10), six of which received official nomenclature as per MGI's curatorial guidelines. All mapping was performed relative to NCBI mouse genome Build 36.
