‼️HORSE OWNERS‼️
If you own or breed splash white horses please take a moment to have a look at this survey to see if you can provide any helpful information. Would love to see more education and data on this topic.
We are fortunate to own a homozygous SW2 filly (I am NOT her breeder) that seems to be one of the rare ones who is healthy, happy, and able to live a normal life.
I own multiple mares who are n/SW2 and I am very thankful that this outcome has come to light so that I am able to adjust and make responsible breeding choices for my mares and their future foals.
🔥 The Hot Topic of the weekend... Splash White Genes in reining breds.
It is our hope to help create some sort of data tracking sheet to inspire researchers at a major university to help us study this further to see what the relationship is to splash genes and birth defects, if any, and if the linebreeding taking place has any correlation as well.
🛡️We will NOT share individual names or pedigrees from this survey with the public. This is a streamlined way to provide a research party a way to trace pedigrees etc in one place.
We are not for bashing, fear-mongering, or anything of the like... But if we as breeders don't do our due diligence for the future what are we doing?
❤️With that being said if you have had issues with a Splash Gene foal or have a viable homozygous Sw2 Foal we would love for you to participate in this survey.
This survey is not for those who have successfully bred multiple splash gene horses we know there are plenty of those.
➡️This is specifically for those who have had issues with a Splash Gene foal or have a viable homozygous Sw2 horse or other combination of white genes creating a Max White that is normal.
It is worth noting in a peer reviewed study: “The PAX3C70Y allele is only 24 years old and occurs exclusively in Quarter and Paint Horses. We did not find a horse homozygous for this mutation, and based on data from mice it is unlikely that a homozygous PAX3C70Y/C70Y horse would be viable. As PAX3 is required for several key steps in neural development, homozygosity for this allele will most likely result in embryonic or fetal lethality [26]. Therefore, the mating of two heterozygous PAX3 +/C70Y horses is not recommended in order to avoid the accidental production of an embryo homozygous for this allele. The MITFC280Sfs*20 and MITFN310S alleles are extremely rare. Data from mice again suggest that these alleles will most likely result in severe clinical phenotypes such as e.g. microphthalmia in the homozygous state [27]. Therefore, horses with such alleles should also not be mated to each other.”
