Dead or deformed foals produced by purebred parents represent an economic and emotional loss to the horse breeder. To avoid repeating production of such defective foals, the breeder may seek assistance in identifying the possible environmental or genetic causes for such animals. Only a few genetic diseases of the horse have been rigorously defined. Selected rare genetic diseases that prevent reproduction, cause the natural death or necessitate the humane destruction of a foal before it fulfills its intended purpose serve as examples for the definition of genetics of other deleterious diseases in the horse.
纯种亲本所产的死胎或畸形马驹会给马匹饲养者带来经济和情感上的损失。为避免再次产出此类有缺陷的马驹，饲养者可能会寻求帮助，以确定导致这些情况的可能环境或遗传因素。目前仅对少数几种马的遗传疾病进行了严格定义。选取一些罕见的遗传疾病为例，这些疾病会阻止繁殖、导致自然死亡或使马驹在达到预期用途前就不得不实施安乐死，以此来定义马的其他有害疾病的遗传学。
