ABSTRACT
We tested the possibility to map loci affecting the acute inflammatory response (AIR) in an (AIRmax AIRmin) F2 intercrossmouse population derived from non-inbred parents, by association analysis in the absence of pedigree information. Using 1064 autosomal single nucleotide polymorphisms (SNPs), we clustered the intercross population into 12 groups of genetically related individuals. Association analysis adjusted for genetic clusters allowed to identify two loci, inflammatory response modulator 1 (Irm1) on chromosome 7 previously detected by genetic linkage analysis in the F2 mice, and a new locus onchromosome 5 (Irm2), linked to the number of infiltrating cells in subcutaneous inflammatory exudates (Irm1 P»6.3 10 7; Irm2 P»8.2 10 5) and interleukin 1 beta (IL-1b) production (Irm1 P»1.9 10 16; Irm2 P»1.1 10 6). Use of a polygenic model based on additive effects of the rare alleles of 15 or 18 SNPs associated at suggestive genome-wide statistical threshold(Po3.4 10 3) with the number of infiltrating cells or IL-1b production, respectively, allowed prediction of the inflammatory response of progenitor AIR mice. Our findings suggest the usefulness of association analysis in combination with genetic clustering to map loci affecting complex phenotypes in non-inbred animal species.
