Pre-implantation genetic diagnosis (PGD) is a procedure used to screen embryos recovered after uterine flush to determine sex and genetic traits through DNA testing prior to implantation in the uterus.
SynchroGait® is a diagnostic DNA test for a genetic variant (A) that has a major impact on the gait and coordination of horses. The discovery by researchers in Sweden showed that the mutation “facilitates lateral gaits, ambling and pace, and inhibits the transition from trot or pace to gallop”. The gait A variant has been identified as a major genetic factor for performance in trotting horses and ability to perform the additional “flying pace” in Icelandic horses.
Dominant white is a variable white spotting pattern caused by many different mutations in the KIT gene. The VGL tests for the four most common mutations known as W5, W10, W20, and W22. Homozygosity for W5, W10, or W22 is thought to be non-viable.
