A recent survey of horse breeds in Europe and the USA found the Warmblood fragile foal syndrome type 1 (WFFS) variant mainly in warmbloods and few other breeds, with no evidence the variant originated in Arabians.
In early April, VGL Director Dr. Rebecca Bellone joined the Equine Veterinary Journal podcast "EVJ in Conversation" to discuss catastrophic breakdown in racehorses as well as her recent paper, which found no evidence of linkage between catastrophic breakdown and the mutation that causes Warmblood fragile foal syndrome type 1 (WFFS).
