Dilated cardiomyopathy is a primary myocardial disease that can result in the development of congestive heart failure and sudden cardiac death. In Doberman pinscher DCM is caused by a deletion in PDK4 gene that has an important regulatory role in cardiac energy metabolism. The penetrance of this deletion mutation in the population studied was approximately 68 %.
Note: Study was performed on American Doberman pinscher population, European population still has not been studied in details.
