The Comprehensive Genetic Test for Left Ventricular Non-Compaction Cardiomyopathy (LVNC) utilizes next-generation sequencing (NGS) to examine 33 genes associated with non-compaction cardiomyopathy and myocardial development disorders. It is a targeted gene panel specifically designed to support accurate diagnosis, risk assessment, and prevention.
More Information
The Comprehensive Genetic Test for Left Ventricular Non-Compaction Cardiomyopathy (LVNC) is a targeted genetic test designed to evaluate hereditary causes of left ventricular non-compaction, a form of cardiomyopathy characterized by abnormal myocardial structure. The comprehensive genetic test for left ventricular non-compaction cardiomyopathy (LVNC) includes the analysis of a set of genes, along with selected non-coding variants, enabling a comprehensive assessment of genetic factors associated with this condition. It is particularly suitable for individuals with a clinical suspicion of left ventricular non-compaction cardiomyopathy (LVNC). Left ventricular non-compaction cardiomyopathy (LVNC) is defined by a spongy appearance of the left ventricle due to excessive trabeculations and deep intertrabecular recesses, which may impair normal cardiac function and predispose to complications.
The comprehensive genetic test for left ventricular non-compaction cardiomyopathy (LVNC) includes key genes such as MYH7, MYBPC3, TTN, LMNA, and TAZ, which are involved in sarcomere function, myocardial structure, and mitochondrial and cytoskeletal integrity. MYH7 and MYBPC3 are essential components of the sarcomere, while TTN contributes to myocardial elasticity. LMNA is important for nuclear structure, and TAZ is associated with mitochondrial function and cardiolipin metabolism. These pathways are critical for normal cardiac development and function. Disruptions in these mechanisms contribute to abnormal myocardial compaction and overlapping cardiomyopathy phenotypes. The comprehensive genetic test for left ventricular non-compaction cardiomyopathy (LVNC) is indicated in individuals presenting with clinical or imaging findings suggestive of left ventricular non-compaction cardiomyopathy (LVNC).
The clinical spectrum of left ventricular non-compaction cardiomyopathy (LVNC) is broad and includes asymptomatic individuals as well as patients presenting with arrhythmias, heart failure, and thromboembolic events. The condition may be identified in both pediatric and adult populations and can occur in isolation or in association with congenital heart defects. Significant overlap exists with hypertrophic and dilated cardiomyopathies, both clinically and genetically. Disease expression varies widely, and some individuals carrying pathogenic variants may exhibit only mild or subclinical features, while others develop severe cardiac dysfunction.
The purpose of the comprehensive genetic test for left ventricular non-compaction cardiomyopathy (LVNC) is to identify pathogenic variants associated with left ventricular non-compaction cardiomyopathy (LVNC), supporting accurate diagnosis and differentiation from other cardiomyopathies with overlapping phenotypes. Genetic findings contribute to improved understanding of myocardial development and the molecular basis of cardiomyopathies. The identification of specific genetic alterations assists in risk assessment, prognosis evaluation, and the development of appropriate long-term monitoring strategies.
A higher genetic risk is confirmed when pathogenic mutations are found in genes associated with left ventricular non-compaction cardiomyopathy (LVNC) and related cardiomyopathies, including MYH7, TTN, and TAZ. A lower risk may be inferred when no mutations are detected, though comprehensive clinical follow-up is still essential. The integration of genetic data with clinical findings and imaging evaluation is critical for precise diagnosis, prognosis, and long-term patient care.
The test is performed in a clinical laboratory accredited to ISO 15189 and certified by CLIA and CAP, ensuring the validity, accuracy and international recognition of the results.
