Primary Institution: Uppsala University
Hypothesis
Is there a genetic mutation responsible for the Silver coat color in horses?
Conclusion
The study identifies a mutation in the PMEL17 gene as the cause of the Silver coat color in horses.
Supporting Evidence
- The missense mutation Arg618Cys was found to be completely associated with the Silver phenotype.
- 64 Silver horses and 85 non-Silver horses were tested for the mutation.
- Significant linkage was found between the Silver phenotype and the genetic marker TKY284.
Takeaway
This study found that a specific change in a gene is what makes some horses have a shiny silver coat.
Methodology
The study involved genotyping and sequencing of the PMEL17 gene in a half-sib family of horses.
Potential Biases
Potential bias in sample selection as only certain breeds were tested.
Limitations
The study may not account for all potential mutations affecting coat color in horses.
Participant Demographics
The study included horses from multiple breeds, including Icelandic, Rocky Mountain, and American Miniature Horses.
