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.

  • ✓Individuals with unexplained neurological symptoms (e.g., muscle weakness, developmental delays, seizures).
  • ✓Patients with a family history of mitochondrial diseases.
  • ✓Diagnosis confirmation for suspected mitochondrial respiratory chain disease.
  • ✓Genetic counseling and family planning for those with a known or suspected TIMM21 mutation.

In plain language

What this test helps you understand

This test helps identify mutations in the TIMM21 gene, which are associated with mitochondrial respiratory chain diseases. It can aid in diagnosing these conditions, particularly in individuals presenting with relevant symptoms or a family history.
The TIMM21 Gene Mitochondrial Respiratory Chain Disease NGS Genetic DNA Test is a specialized diagnostic tool used to detect genetic changes (mutations) in the TIMM21 gene. Mutations in this gene can lead to mitochondrial diseases, which affect the body's ability to produce energy and can impact various organs, particularly the nervous system.

This test employs advanced Next-Generation Sequencing (NGS) technology to provide a detailed analysis of the TIMM21 gene. It helps identify specific mutations that may be responsible for symptoms related to mitochondrial respiratory chain dysfunction.

Understanding mitochondrial diseases is crucial for proper management. This test can provide valuable information for diagnosis, treatment planning, and genetic counseling for affected individuals and their families.

PreparationGenerally, no special preparation is required for a blood draw. However, confirm with the laboratory for any specific instructions.
SampleBlood sample (usually collected in an EDTA tube). Confirm specific requirements with the laboratory before booking.
MethodologyNext-Generation Sequencing (NGS) of the TIMM21 gene.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test specifically analyzes the TIMM21 gene. It may not detect mutations in other genes associated with mitochondrial diseases. A negative result does not completely rule out a mitochondrial disorder. 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

Mitochondrial diseases are disorders caused by mutations in genes responsible for the function of mitochondria, the energy-producing parts of cells. They can affect various parts of the body, often the brain, muscles, and nerves.
Individuals with symptoms suggestive of a mitochondrial disorder, such as muscle weakness, developmental delays, seizures, or vision/hearing loss, especially if there is a family history of similar conditions, may be candidates for this test.
NGS technology used in this test is highly accurate for detecting mutations within the TIMM21 gene. However, it's important to discuss the specific limitations and interpretation of the results with your doctor.
Results will be provided through your referring physician. Genetic counseling is often recommended to help understand the implications of the results for your health and family.
Insurance coverage varies. Please check with your insurance provider regarding coverage for genetic testing.
