We did not find any evidence linking dog obesity traits to structural variants in or near genes that are considered crucial for obesity development, such as genes involved in the leptin-melanocortin signalling pathway and genes important for neuronal circuitry development (e.g., BDNF, NTRK2, SEMA3A-G). This evidence concerns the gene BDNF and obesity due to melanocortin 4 receptor deficiency.
