Test Code DCMGP Dilated Cardiomyopathy Multi-Gene Panel, Next-Generation Sequencing, Blood

Useful For

Providing a comprehensive genetic evaluation for patients with a personal or family history suggestive of hereditary dilated cardiomyopathy (DCM)


Establishing a diagnosis of a hereditary DCM, and in some cases, allowing for appropriate management and surveillance for disease features based on the gene involved


Identifying a pathogenic variant within a gene known to be associated with disease features that allows for predictive testing of at-risk family members

Reporting Name

Dilated Cardiomyopathy Panel, B

Specimen Type

Whole Blood EDTA

Advisory Information
