Frequency of gray coat color in native Chinese horse breeds

K. X. Gao, Chen, N. B., Liu, W. J., Li, R., Lan, X. Y., Chen, H., Lei, C. Z., and Dang, R. H., Frequency of gray coat color in native Chinese horse breeds, vol. 14, pp. 14144-14150, 2015.

Gray horses are born colored, and they then gradually lose their hair pigmentation. Tremendous progress has been made in identifying the genes responsible for graying with age in horses in recent years. Results show that gray coat color in horses is caused by a 4.6-kb duplication in intron 6 of the syntaxin 17 gene (STX17), which constitutes a cis-acting-regulatory mutation. However, little is known about the gray phenotype in native Chinese horses. This study was conducted to explore the frequency distribution of the gray mutation in native Chinese horse breeds.
