Abstract Text: Piglet splay leg syndrome is one of the most frequent genetic defects, with affected animals having impaired ability to stand and walk. The etiology and pathogenesis of the genetic defect is complex and poorly understood. In order to identify genetic variants associated with piglet splay leg syndrome, a genome-wide association study (GWAS) was conducted to identify significant single nucleotide polymorphisms (SNPs) associated with this defect. Nine significant SNPs were detected on four chromosomes, and 108 novel candidate genes were identified based on the Sscrofa 10.2 assembly. However, validation studies in a larger set of animals, as well as gene function studies will be required for validation of the results. To our knowledge, this is the first study aiming to identify markers and genes associated with piglet splay leg syndrome by GWAS.
