What is a Hereditary Spastic Paraplegia Gene Panel Test?
The hereditary spastic paraplegia gene panel test is a specialised genetic test that examines multiple genes associated with hereditary spastic paraplegia (HSP), a group of inherited neurological conditions that cause progressive stiffness and weakness in the legs. The test uses next-generation sequencing (NGS), a technology that reads DNA in detail, to identify disease-causing mutations across a large number of genes in a single run. It is also referred to as the HSP gene panel or Spastic Paraplegia Gene Panel. A chorionic villus (CVS) sample is used for this test.
What Does a Hereditary Spastic Paraplegia Gene Panel Test Measure?
This test analyses up to 128 genes known to be linked with HSP. It looks for single-nucleotide variants (changes in individual DNA letters) as well as copy number variants (missing or duplicated sections of genes). The table below lists some of the key genes examined.
| Gene | Role in HSP |
|---|---|
| SPAST | One of the most frequently mutated genes in HSP; affects nerve cell function in the spinal cord |
| ATL1 | Linked to early-onset pure HSP; affects proteins that transport materials within nerve cells |
| SPG11 | Associated with complicated HSP, which involves additional neurological features |
| KIF5A | Involved in nerve cell maintenance and transport |
| REEP1 | Affects the structural integrity of nerve cells |
| CYP7B1 | Involved in metabolic processes that support nerve cell health |
| Additional genes (up to 128 total) | Cover the full genetic range of known HSP subtypes |
Why is a Hereditary Spastic Paraplegia Gene Panel Test Done?
Doctors order this test when a patient's symptoms or family history suggest HSP. It helps confirm a diagnosis and guides further management.
Common Symptoms That May Require This Test
The following symptoms often prompt a doctor to recommend the hereditary spastic paraplegia gene panel test:
- Progressive stiffness (spasticity) in the legs
- Difficulty walking or a noticeably changed gait
- Frequent tripping or stumbling
- Walking on the toes (toe-walking)
- Exaggerated reflexes (hyperreflexia)
- Reduced ability to feel vibrations in the lower limbs
- Reduced bladder control
Conditions This Test Can Help Detect
This panel can assist in identifying the following conditions:
- Pure (uncomplicated) HSP, where symptoms are limited to lower limb spasticity, weakness, and bladder involvement
- Complex (complicated) HSP, which includes additional features such as seizures, intellectual disability, ataxia (loss of coordination), peripheral neuropathy, or vision and hearing problems
- More than 80 distinct genetic subtypes of HSP
- Related conditions such as adrenoleukodystrophy and certain metabolic disorders
How to Prepare and What to Expect
Preparing correctly for this test helps ensure that the sample is suitable for analysis and that results are accurate.
Do You Need to Fast?
No fasting is required before this test. You can eat and drink normally on the day of sample collection.
Practical Tips Before Your Test
The following steps will help your test go smoothly:
- Bring a detailed clinical history, including your symptoms, previous test results, and family history, as this is required for the test
- Inform the laboratory if you have had a recent blood transfusion or bone marrow transplant, as donor DNA in your sample may affect results
- Ensure the sample container is correctly labelled with your full name, date of birth, and the date of collection
- Arrange for genetic counselling before the test if possible, so you understand what the results may mean for you and your family
Step-by-Step Procedure
The hereditary spastic paraplegia gene panel test may use different sample types depending on the clinical indication. Home collection may be available for peripheral blood or saliva samples. Specialised prenatal samples such as CVS or amniotic fluid are collected at authorised healthcare facilities under medical supervision. Genetic counselling may be recommended before and after testing to help understand the results and their implications.
Peripheral Blood Collection
- Genetic diagnostic or healthcare team confirms the patient’s identity before sample collection.
- The skin over the collection site is cleaned with an antiseptic solution.
- A small blood sample is collected from a vein in the arm using a sterile needle.
- The sample is collected in an EDTA tube (purple/lavender-top tube).
- The sample is labelled and transported to the laboratory.
Buccal Swab/Saliva Collection
- A healthcare professional or trained staff member collects the sample.
- For a buccal swab, a soft swab is gently rubbed inside the cheek to collect cells.
- For saliva collection, the patient provides a saliva sample in a sterile container.
- The sample is labelled and sent to the laboratory.
Chorionic Villus Sampling (CVS)
- The doctor explains the procedure and obtains informed consent before collection.
- A trained specialist collects a small placental tissue sample called chorionic villi under ultrasound guidance.
- The sample is placed in a sterile container and transported to the laboratory.
Amniotic Fluid Collection
- The abdomen is cleaned with an antiseptic solution before the procedure.
- Under ultrasound guidance, a trained specialist collects a small amount of amniotic fluid (fluid surrounding the baby during pregnancy) using a sterile needle.
- The sample is transferred to a sterile tube and sent to the laboratory.
Factors That Can Affect Accuracy
The following factors may influence the reliability of your results:
- A recent blood transfusion or allogeneic stem cell transplant (donor DNA can interfere with analysis)
- Poor sample quality due to inadequate storage or labelling errors
- Mosaicism, where only a proportion of cells carry the mutation, which can be harder to detect
- Variants located in non-coding regions or genes not included in the panel
Understanding Your Hereditary Spastic Paraplegia Gene Panel Test Results
Results from this test are qualitative, meaning they do not produce numerical values. Instead, each variant identified is classified into one of the categories below. Always review your results with a qualified doctor or genetic counsellor.
| Result Category | What it Means |
|---|---|
| Pathogenic variant | A disease-causing mutation has been identified |
| Likely pathogenic variant | A variant strongly suspected to cause the condition |
| Variant of uncertain significance (VUS) | A variant was found, but its clinical significance is not yet clear |
| Benign or likely benign | The variant found is not associated with disease |
| Negative | No disease-causing variants were detected in the genes tested |
These categories follow the guidelines of the American College of Medical Genetics and Genomics (ACMG). Your doctor will interpret your results based on your clinical history, family background, and overall health. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain situations can affect how results are interpreted:
A recent allogeneic haematopoietic stem cell transplant or blood transfusion may introduce donor DNA into your sample, which can produce inaccurate results. If this applies to you, inform your doctor before testing. Degraded or poor-quality DNA may also reduce sequencing accuracy, making it important to follow storage and handling instructions carefully.
How to Maintain Healthy Levels
Because HSP is a genetic condition, it cannot be prevented through lifestyle changes. However, the following general steps can support overall well-being after a diagnosis:
- Regular physical therapy and guided exercise can help maintain leg strength and mobility
- Genetic counselling after receiving results can support informed family planning decisions
- Early diagnosis allows for timely symptom management and appropriate specialist referral
