Clinical conditions of the dilated cardiomyopathy in the American Cocker spaniel (ACS) family developed dilated cardiomyopathy and a cataract were analyzed. Protein expressions and various gene analyses participating in outbreak of the dilated cardiomyopathy were analyzed. As a result, the outbreak of dilated cardiomyopathy in ACS family was found in this study. Outbreaks of cardiomyopathy and cataract were associated with the decrease of the expression level of Alpha B-crystallin (CRYAB) in the skeletal muscle. Single nucleotide polymorphisms of the amino acid non-coding regions of CRYAA or CRYAB gene were found, suggesting a relationship between cardiomyopathy and genetic polymorphism.

对美国可卡犬(ACS)家系扩张型心肌病合并白内障的临床情况进行了分析。对参与扩张型心肌病暴发的蛋白表达和各种基因分析进行分析。因此，本研究发现了急性冠脉综合征家系中的扩张型心肌病的暴发。心肌病和白内障的发生与骨骼肌中αB-晶状体蛋白(CryAB)的表达水平降低有关。CRYAA或CryAB基因的氨基酸非编码区存在单核苷酸多态，提示心肌病与遗传多态有关。
