What is a Cardiomyopathy Gene Panel Test?
The cardiomyopathy gene panel test is a specialised genetic test that examines multiple genes linked to hereditary diseases of the heart muscle. It uses next-generation sequencing (NGS), an advanced DNA analysis method that reads many genes at the same time. Doctors prescribe this test for individuals who show signs of cardiomyopathy or have a family history of heart muscle disorders or sudden cardiac death. Samples accepted include chorionic villus (CVS), amniotic fluid, or peripheral blood collected in an EDTA tube.
What Does a Cardiomyopathy Gene Panel Test Measure?
This test scans genes across several biological categories to find mutations that may cause or contribute to cardiomyopathy. The table below outlines the main gene categories analysed.
| Gene Category | Examples | What They Do |
|---|---|---|
| Sarcomere genes | MYBPC3, MYH7, TNNT2, TNNI3 | Build the contractile unit of heart muscle |
| Cytoskeletal genes | DES, VCL | Form the structural framework of heart muscle cells |
| Desmosomal genes | PKP2, DSP, DSG2 | Hold heart muscle cells together |
| Ion channel genes | SCN5A | Manage electrical signalling in the heart |
| Nuclear lamina genes | LMNA | Support the structure of the cell nucleus |
The test identifies single-nucleotide variants (small changes in individual DNA letters) as well as copy number variants (deletions or duplications of gene sections).
Why is a Cardiomyopathy Gene Panel Test Done?
Cardiomyopathy can run in families, and identifying a genetic cause helps guide clinical decisions for both the patient and their relatives. This test is ordered when symptoms or family history suggest a hereditary heart muscle condition.
Common Symptoms That May Require This Test
Several cardiac symptoms may prompt a doctor to recommend the cardiomyopathy gene panel test. These include:
- Palpitations (a fluttering or pounding sensation in the chest)
- Shortness of breath, especially during physical activity
- Chest pain or pressure
- Fainting (syncope) or near-fainting episodes
- Swelling (oedema) in the legs or ankles
- Unusual fatigue
- Dizziness
Conditions This Test Can Help Detect
This test can help identify the genetic basis of several distinct heart muscle conditions:
- Hypertrophic cardiomyopathy (HCM): abnormal thickening of the heart muscle
- Dilated cardiomyopathy (DCM): enlargement and weakening of the heart muscle
- Arrhythmogenic cardiomyopathy (ACM/ARVC): replacement of heart muscle with fatty or scar tissue
- Left ventricular noncompaction (LVNC): a spongy, irregular appearance of the heart muscle
- Restrictive cardiomyopathy (RCM): abnormal stiffening of the heart muscle
- Transthyretin (TTR) amyloidosis-associated cardiomyopathy: a protein-deposit disease affecting the heart
How to Prepare and What to Expect
No special dietary preparation is needed for this test. However, there are a few important steps to follow before your appointment.
Do You Need to Fast?
No fasting is required. You may eat and drink normally before sample collection. There are no dietary restrictions associated with the cardiomyopathy gene panel test procedure.
Practical Tips Before Your Test
Preparing a few key items in advance will help ensure an accurate and efficient test experience. Keep the following in mind:
- Bring a detailed clinical history, including your symptoms, previous test results, and family history, as this is required for the test
- Document any family history of heart muscle disease, sudden cardiac death, or unexplained deaths before your appointment
- Bring previous cardiac reports, such as echocardiogram or ECG results
- Inform your doctor about any recent blood transfusions or bone marrow transplants, as these may affect results
- Pre-test genetic counselling is recommended to help you understand what the results may mean for you and your family
Step-by-Step Procedure
The cardiomyopathy gene panel test procedure involves collecting one or more biological samples. Below are the steps for each sample type accepted at Lupin Diagnostics.
For Chorionic Villus (CVS) Sample:
- A gynaecologist or trained specialist collects a small amount of tissue (30 mg) from the chorionic villi using a sterile procedure.
- The sample is placed in a sterile white container.
- It is stored at 2 to 8 degrees Celsius and dispatched to the laboratory.
For Amniotic Fluid:
- A doctor performs an amniocentesis procedure to collect 20 ml of amniotic fluid using a fine needle.
- The sample is placed in a dedicated Falcon tube and labelled appropriately.
- It is refrigerated and transported promptly to the laboratory.
For Peripheral Blood:
- A trained phlebotomist cleans the skin on your inner arm.
- A small blood sample (3 ml) is drawn from a vein into a lavender-capped EDTA tube.
- DNA is extracted from the sample, purified, and prepared for sequencing.
- Next-generation sequencing analyses the relevant genes simultaneously.
- Results are compared to a reference genome and classified following established guidelines.
Factors That Can Affect Accuracy
Certain conditions and circumstances may influence the reliability of your results:
- Recent allogeneic blood transfusion or stem cell transplant (donor DNA may interfere)
- Haematological malignancies (blood cancers) that may require an alternative sample source
- Poor sample quality or insufficient DNA quantity
- Somatic mosaicism, where different cells carry different genetic compositions
- Technical limitations in reading certain gene regions
Understanding Your Cardiomyopathy Gene Panel Test Results
Results from this test are classified according to established international guidelines for variant interpretation. A qualified doctor or genetic counsellor should always review your results in the context of your clinical picture and family history.
| Result Category | What it Means |
|---|---|
| Negative (no variants detected) | No disease-causing variants found in the genes tested |
| Pathogenic variant | A confirmed disease-causing mutation has been identified |
| Likely pathogenic variant | Strong evidence of disease causation; treated similarly to a confirmed finding |
| Variant of uncertain significance (VUS) | The clinical meaning is unclear and requires reassessment over time |
| Benign or likely benign | The variant is not expected to cause disease |
Disclaimer: These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain patient circumstances may affect how results are interpreted:
- Patients who have recently undergone an allogeneic stem cell transplant or received a non-leukocyte reduced blood transfusion may receive inaccurate results because donor DNA can be present in the sample. An alternative sample source may be required.
- Patients with blood cancers (haematological malignancies) may need to provide a sample from an alternative tissue source, such as skin fibroblasts, for accurate analysis.
How to Maintain Healthy Levels
While genetic results cannot be changed, general heart health habits are beneficial for everyone with a family history of cardiomyopathy. Consider the following:
- Follow a heart-friendly diet that is low in salt and saturated fat.
- Stay physically active at a level recommended by your cardiologist.
- Attend regular cardiac check-ups, particularly if a genetic variant has been identified in your family.

Frequently Asked Questions
The cardiomyopathy gene panel test is a genetic test that identifies mutations in genes known to cause heart muscle diseases. It uses next-generation sequencing to analyse multiple genes at once. The test helps confirm a diagnosis, guide clinical management, and identify family members who may carry the same genetic risk.
This test is suitable for individuals diagnosed with or suspected of having cardiomyopathy, including HCM, DCM, ARVC, LVNC, or RCM. It is also relevant for those with a family history of heart muscle disease, unexplained fainting, or sudden cardiac death in a close relative.
No fasting is needed. You can eat and drink as normal before your appointment. There are no specific dietary restrictions for this test.
A negative result means no disease-causing variants were identified in the genes tested. However, given the technical limitations of any genetic test, a negative result does not completely rule out a hereditary condition. Your doctor will continue to evaluate you based on symptoms and clinical findings.
A confirmed pathogenic result helps establish a genetic diagnosis and may guide further clinical decisions. Close relatives such as parents, siblings, and children may then choose cascade testing to find out whether they have inherited the same mutation. Your doctor or genetic counsellor will explain the next steps.
At Lupin Diagnostics, the cardiomyopathy gene panel test report is delivered within 35 days from the date of sample collection. This is because NGS-based analysis involves multiple complex laboratory steps that take time to complete accurately.
A VUS means that a change in the gene was detected, but there is currently not enough evidence to confirm whether it causes disease. VUS findings are not used for family cascade testing. As more genetic data becomes available over time, these variants may be reclassified as benign or pathogenic.
