Dilated Cardiomyopathy and Left Ventricular Noncompaction Cardiomyopathy Gene Panel, Varies
Use
This test provides a genetic evaluation for patients with a personal or family history suggestive of hereditary forms of dilated cardiomyopathy or left ventricular noncompaction (LVNC). It aids in establishing a diagnosis of these hereditary forms by utilizing next-generation sequencing to detect single nucleotide and copy number variants in 63 genes associated with these conditions. Identification of a disease-causing variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling.
Special Instructions
Not provided.
Limitations
Next-generation sequencing may not detect all types of genomic variants and has certain technical limitations, including regions of homology and high guanine-cytosine content that may not be effectively evaluated. False negatives or positives are possible, and balanced structural rearrangements may not be detected. The test does not assess for low levels of mosaicism or differentiation between somatic and germline variants. Sensitivity is estimated above 99% for SNVs and certain indels, but deletions-insertions of 40 or more bp may be less reliably detected.
