Adaptive variation in butyrylcholinesterase-influenced lipid metabolism during horse domestication
20 Aug 2026
Abstract excerpt
Lipid metabolism influences horse athletic performance, yet its genetic basis remains unclear. Here, we investigate the genetic basis of lipid metabolic traits by quantifying key metabolic parameters and sequencing the genomes of 298 horses. We identify a missense mutation (ECA19:9,198,989, G>C) in the BCHE gene that is strongly associated with lipid metabolism, especially butyrylcholinesterase (BChE) activity....
