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.

✓Males with developmental delays or cognitive impairment.
✓Individuals with symptoms suggestive of Christianson syndrome.
✓Family history of X-linked intellectual disability.
✓Suspected genetic cause for neurological symptoms.
✓Genetic counseling for families with affected members.

In plain language

What this test helps you understand

This test helps identify specific genetic mutations in the SLC9A6 gene that are known causes of certain neurological disorders, particularly X-linked syndromic mental retardation (Christianson syndrome). It can confirm a diagnosis in individuals presenting with relevant symptoms and family history, guiding appropriate medical management and genetic counseling.

This genetic test identifies mutations in the SLC9A6 gene, which are linked to neurological conditions, including X-linked syndromic mental retardation, also known as Christianson syndrome. This condition primarily affects males and is characterized by developmental delays and cognitive impairment. The test uses Next Generation Sequencing (NGS) technology to analyze DNA for specific changes in the SLC9A6 gene. Understanding the genetic basis of these conditions can aid in diagnosis, management, and family planning. Discuss the relevance of this test with your doctor.

PreparationNo special preparation is required for a blood draw. Follow standard instructions provided by the collection center.

SampleBlood sample (EDTA tube) or Extracted DNA. An FTA card with one drop of blood may also be acceptable. Confirm specific requirements with the laboratory before booking.

MethodologyNext Generation Sequencing (NGS) is used to detect mutations within the SLC9A6 gene.

PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.

This test specifically analyzes the SLC9A6 gene. It may not detect mutations in other genes that can cause similar symptoms. A negative result does not completely rule out a genetic cause for the condition. Confirm with the laboratory before booking.

Questions people ask

Frequently asked questions

Christianson syndrome is a rare genetic disorder primarily affecting males, characterized by intellectual disability, developmental delays, and sometimes seizures or behavioral issues. It is caused by mutations in the SLC9A6 gene.

This test is recommended for males with symptoms like developmental delays or cognitive impairment, especially if there is a family history of related conditions. Consult your doctor to determine if this test is appropriate.

A positive result indicates that a mutation in the SLC9A6 gene associated with the condition has been identified. This can help confirm a diagnosis and guide medical management.

A negative result means no mutations in the SLC9A6 gene were detected by this test. It does not rule out other genetic causes for the symptoms. Further evaluation may be needed.

A blood sample is typically required. In some cases, extracted DNA or a dried blood spot on an FTA card may be used. Confirm the required sample type with the laboratory.

The turnaround time is approximately 3 to 4 weeks from the time the sample is received by the laboratory. Confirm the current turnaround time before booking.
