Genetic Testing at Gluck offers several disease mutation tests including JEB, OLWS, Myotonia, Dwarfism in Miniature Horses, Dwarfism in Friesian, and Hydrocephaly in Friesian. In 2016, the laboratory started offering a test to determine CXCL16 Haplotype, a genetic basis for the likelihood of a stallion becoming a long term shedder/carrier of the Equine Arteritis Virus (EAV). More information is available on each of these tests by following the links to the left.
