Unlike previous work that focused
on gene polymorphism, the current research evaluates the impact of gene
expression on horses coat coloration. Skin samples were collected from horses
with white and black coat colors and the genes were identified through the use
of RNA sequencing. In this study Li and his colleagues were able to provide a collection
of genes that are differentially expressed in horse skins of different colors. Their
findings indicate that the genes such as DCT,
HPD and TAT are involved in tyrosine metabolism which is responsible
for melanin production. The authors indicate that the deregulation of these
genes is associated to formation of coat coloration and skin health issues
