Dilated Cardiomyopathy
Dilated cardiomyopathy panel [121 genes]: this panel is indicated as a first diagnostic approach upon clinical suspicion of familial or idiopathic DCM. This is the most complete panel on the market for this pathology, including genes that can also be associated with cardiac conduction diseases and/or muscle alterations, both in clinical and subclinical phase.
It includes priority genes recommended in clinical practice guidelines and clearly associated with this disease. Sporadically associated secondary genes are also included, along with candidate genes gathered from a systematic literature review.

Cardiomyopathies general panel [204 genes]: it includes 204 genes covering the whole presentation spectrum of cardiomyopathies (hypertrophic, dilated, restrictive, and non-compaction), also including RASopathies, storage diseases, and congenital heart diseases.
It includes priority genes that have a clear association with the development of these diseases. It also includes secondary genes, which have sporadically been associated to them, as well as candidate genes gathered from a systematic review of the literature.
Cardiomyopathies, Arrhythmias, and Sudden Death General Panel [251 genes]: this panel is mainly aimed at the diagnosis of cases where it is not possible to establish a clearly defined phenotype, but where cardiac arrhythmias are the main manifestation.
It is mainly intended for subjects with personal or familial history of sudden death with unknown origin or subjects with ventricular fibrillation of unknown origin that meet the above-mentioned characteristics.
Cardiovascular diseases general panel [405 genes]: this panel includes all genes associated or potentially associated with the development of inherited cardiovascular diseases as well as genes associated with increased global/general cardiovascular risk.
It covers a group of heterogeneous diseases, and genetic testing allows for the differential diagnosis between them. It is also useful when a multigenic etiology is suspected.
It should be considered when an exhaustive study of all genes related to cardiovascular pathologies is intended, especially in cases of sudden death where clinical or pathological information is incomplete or the diagnosis is unclear.
As for research, it is an attractive alternative to the exomes because it includes both genes with proven pathogenicity and candidate genes. The study ensures maximum yield with adequate coverages (which allows for assessing structural variants, such as large deletions and duplications).

This panel is indicated as a first diagnostic approach upon clinical suspicion of familial DCM:
- It can identify the causative mutation, which confirms the diagnosis of the disease and constitutes an important tool for differential diagnosis, since its presentation frequently overlaps with other cardiomyopathies.
- Not all mutations in different genes show a similar behavior: they are usually associated with a specific set of symptoms and with a different prognosis (for example LMNA mutations). This helps performing the appropriate risk stratification for the disease and foreseeing possible complications.
- By detecting a pathogenic mutation, the test can be used with a predictive value, constituting the cornerstone of genetic counseling. It is a cost-effective strategy for family monitoring, since it allows detecting carriers at risk who must follow the appropriate clinical monitoring (given that they are highly likely to develop the disease in the future). Contrarily, non-carriers present the same risk as the general population.

The probability of detecting a causative mutation in a patient under suspicion of familial dilated cardiomyopathy is close to 50%. In any event, diagnostic yield depends on multiple variables such as number of relatives affected, clinical suspicion, age, race, origin, etc.
