Variation in the MC1R, ASIP, and MATP genes responsible for coat color in Kiso horse as determined by SNaPshot™ genotyping.
Abstract: Kiso horse is a breed of Japanese native horses. In this study, to clarify coat color gene variation in Kiso horses, we used SNaPshot™ genotyping to evaluate variation in MC1R, ASIP, and MATP genes at the Extension (E), Agouti (A), and Cream dilution (C) loci. The coat color of 149 horses was documented. The coat color of 140, 3, and 6 horses was bay, chestnut, and buckskin, respectively. Furthermore, the frequency of alleles E, e, A, a, C, and Cr was 0.80, 0.20, 0.86, 0.14, 0.98, and 0.02, respectively. Current status of coat color genes in Kiso horses was clarified, and this information will help plan further conservation of the horses.

This research article reveals an investigation into the genetic factors responsible for coat color differences in the Kiso breed of Japanese horses using a gene-typing method called SNaPshot™. The target genes studied were MC1R, ASIP, and MATP, which are linked to coat color in horses, and the results aim to assist in future conservation efforts for this breed.
Objective of the Research
- The main objective of this study was to determine the variations in three specific genes (MC1R, ASIP, and MATP) that are responsible for the coat color in Kiso horses. The researchers used the SNaPshot™ genotyping method to achieve this.
Research Methodology
- Through the use of the SNaPshot™ genotyping, the researchers assessed the variations in the three mentioned genes at different locations (loci) namely the Extension (E), Agouti (A), and Cream dilution (C).
- The study sample included 149 Kiso horses whose coat colors were documented.
Outcomes
- Out of the total horses, 140 had a bay coat color, 3 were chestnuts, and 6 were buckskin.
- The frequency of alleles E, e, A, a, C, and Cr (which represent the genetic variations at the loci) was found to be 0.80, 0.20, 0.86, 0.14, 0.98, and 0.02, respectively. This data depicts the distribution of these genetic variants amongst the examined Kiso horses.
Implications
- The findings of this research bring clarity to the status of coat color genes in the Kiso horses, exposing the genetic basis behind different coat colors within the breed.
- Furthermore, the information derived from the study can aid in the planning of future conservation strategies for Kiso horses, by providing insights regarding the genetic diversity and distribution in the breed.
