01

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Symptoms suggestive of Joubert syndrome (e.g., developmental delay, coordination issues, abnormal eye movements).
  • ✓Family history of Joubert syndrome.
  • ✓Confirmation of a clinical diagnosis.
  • ✓Genetic counseling for individuals or families affected by neurological disorders.
  • ✓Prenatal diagnosis in families with a known history of TCTN2-related Joubert syndrome.

In plain language

What this test helps you understand

This test helps identify specific genetic mutations in the TCTN2 gene that are known to cause Joubert syndrome. It aids in confirming a clinical diagnosis, understanding the genetic basis of the condition, and providing information for genetic counseling and family planning.
The TCTN2 Gene Joubert Syndrome Type 24 NGS Genetic DNA Test is an advanced genetic analysis designed to detect mutations in the TCTN2 gene. Mutations in this gene are linked to Joubert syndrome, a rare genetic disorder affecting the brain, particularly the cerebellum, which controls balance and coordination. This condition can also impact breathing, eye movements, and cognitive development. Early and accurate diagnosis through this test is important for understanding the condition, managing symptoms, and planning appropriate care. This test utilizes Next-Generation Sequencing (NGS) technology to analyze the DNA for specific genetic variations. Genetic counseling is recommended before and after testing to help understand the results and their implications.

SampleBlood sample (usually collected in an EDTA tube). Confirm specific requirements with the laboratory before booking.
MethodologyNext-Generation Sequencing (NGS) is used to analyze the TCTN2 gene for pathogenic variants.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test specifically analyzes the TCTN2 gene. It will not detect mutations in other genes that can cause Joubert syndrome or similar conditions. A negative result does not completely rule out Joubert syndrome if clinical suspicion remains high. Confirm with the laboratory before booking.

What common result terms mean

PositiveA finding was identified. Your clinician or counselor will explain what it means for your care.
NegativeThe specific finding tested for was not identified. It does not rule out every possible cause.
VUSA variant was found, but current evidence is not enough to classify it. Your counselor can explain follow-up.

Questions people ask

Frequently asked questions

Joubert syndrome is a rare genetic disorder affecting the brain, primarily the cerebellum, leading to issues with coordination, balance, breathing, and eye movements.
This test specifically looks for mutations (changes) in the TCTN2 gene, which are known to cause a specific type of Joubert syndrome.
Genetic counseling helps you understand the test, its potential results, the implications for you and your family, and how to interpret the findings.
No, this test only analyzes the TCTN2 gene. Other genes can also cause Joubert syndrome, so a negative result doesn't rule it out entirely.
A blood sample is typically required for this test. We offer sample collection at our branches or potentially home collection; please inquire for details.
Turnaround time varies. Please contact the laboratory for the current estimated timeframe.
