Dead or deformed foals produced by purebred parents represent an economic and emotional loss to the horse breeder. In order to avoid producing such defective foals in the future, the breeder may seek guidance in determining whether their origin is environmental or genetic. Only a few genetic diseases of horses 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 collecting evidence to define the genetics of other deleterious diseases in the horse. In advising breeders how to avoid genetic defects in future foals, the professional needs to verify with appropriate evidence that the defect is genetic in origin, to discuss the mode of inheritance with the owners, and to advise them of the findings in writing so that they have a reference for making decisions.
纯种亲本所生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。为了避免未来再产出此类有缺陷的马驹，饲养者可能会寻求指导，以确定这些马驹的问题是源于环境还是遗传。目前仅有少数马的遗传疾病得到了严格定义。挑选出的一些罕见遗传疾病，这些疾病会阻止繁殖、导致自然死亡，或者在马驹达到预期用途之前就需要对其进行安乐死，以此作为收集证据来定义马的其他有害疾病遗传学特征的示例。在为饲养者提供如何避免未来马驹出现遗传缺陷的建议时，专业人员需要用适当的证据来证实该缺陷源于遗传，与马主讨论遗传方式，并以书面形式告知他们调查结果，以便他们在做决策时有参考依据。
