This study was done to search for positional candidate genes associated with the back fat thickness trait using a Genome-Wide Association Study (GWAS) in purebred Yorkshires (N = 1755). Genotype and phenotype analyses were done for 1,642 samples. As a result of the associations with back fat thickness using the Gemma program (ver. 0.93), when the genomewide suggestive threshold was determined using the Bonferroni method (p = 1.61 × 10<SUP>-5</SUP>), the single nucleotide polymorphism (SNP) markers with suggestive significance were identified in 1 SNP marker on chromosome 2 (MARC0053928; p = 3.65 × 10<SUP>-6</SUP>), 2 SNP markers on chromosome 14 (ALGA0083078; p = 7.85 × 10<SUP>-6</SUP>, INRA0048453; p = 1.27 × 10<SUP>-5</SUP>), and 1 SNP marker on chromosome 18 (ALGA0120564; p = 1.44 × 10<SUP>-5</SUP>). We could select positional candidate genes (KCNQ1, DOCK1, LOC106506151, and LOC110257583), located close to the SNP markers. Among these, we identified a potassium voltage-gated channel subfamily Q member gene (KCNQ1) and the dedicator of cytokinesis 1 (DOCK1) gene associated with obesity and Type-2 diabetes. The SNPs and haplotypes of the KCNQ1 and DOCK1 genes can contribute to understanding the genetic structure of back fat thickness. Additionally, it may provide basic data regarding marker assisted selection for a meat quality trait in pigs.
