Hayward et al. (2020) did genome-wide association study (GWAS) in 3 canine breeds; 14 suggestive genes were found, but none was located in the areas causing WS as their symptoms indicated, and the genes had no overlap between species. Numerous labs had tried to find the causative gene for the natural deafness canine breeds; only few identified genes, like SOX10 (Hansen et al., 2010) and OTOF (Cargill, 2004), were verified genes responsible for human deafness. This evidence concerns the gene OTOF and deafness.
