Abstract:

 The aim of the present study was to narrow down the range of previous genome wide association study (GWAS) , and to provide valid candidate genes for the large-scale group validation. Seven immune traits including four blood parameters(hematocrit (HCT), hemoglobin(HGB), mean corpuscular hemoglobin (MCH), mean cell volume (MCV)) and three T lymphocyte subpopulation parameters(CD4+CD8-CD3+, CD4-CD8+CD3+ and CD4+CD8-CD3+/CD4-CD8+CD3+)were measured in a porcine intercross population(Large White×Min zhu). Six haplotype blocks were built using the significant SNPs tested in the previous GWAS. Association studies between the haplotype blocks and the immune traits were performed. The result showed that the three blocks on SSC7 were significantly associated with the three T lymphocyte subpopulation parameters, the block7-3 on SSC7 was significantly associated with HGB and HCT, and the three blocks on SSC8 were significantly associated with MCH and MCV. The six blocks contained five genes ABCF1, PPP1R10, GRM4, ALB and AFP. Combination of these results, the five genes could be used as potential candidate genes for the study on immune traits.
