Graying with age is a common coat color variant in horses, characterized by progressive hair graying and susceptibility to skin melanoma. In a new study published in Nature Communications, an international consortium led by scientists from Uppsala University (Sweden) now reports that the speed of graying and susceptibility to melanoma are determined by the copy number of a small duplicated DNA sequence in the gene Syntaxin 17.
