BIEC2-808543 SNP in the LCORL Gene is Associated with Body Conformation in the Yili Horse

Recently, a SNP (BIEC2-808543) was demonstrated to be associated with equine body size in horses. In this study, we genotyped BIEC2-808543 SNPs in 314 Yili horses in order to evaluate the association between genotype and body composition traits, such as body weight, withers height, chest circumference, and cannon circumference. Results indicate significant associations between polymorphisms of this SNP and body conformation in Yili horse populations. Based on these results, we hypothesize that BIEC2-808543 is strongly related to body conformation of Yili horses and has the potential to be used for marker-assisted selection.
