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.

  • ✓Progressive hearing loss
  • ✓Neurological symptoms like muscle weakness or atrophy
  • ✓Family history of Brown-Vialetto-Van Laere syndrome
  • ✓Unexplained symptoms referred by an ENT specialist
  • ✓Genetic counseling for individuals with suspected hereditary neurological disorders

In plain language

What this test helps you understand

This test helps confirm or rule out a diagnosis of Brown-Vialetto-Van Laere syndrome by identifying pathogenic variants in the SLC52A3 gene. It can aid in understanding the cause of symptoms like progressive hearing loss and neurological issues, guiding management strategies and informing family members about potential risks.
The SLC52A3 Gene Brown-Vialetto-Van Laere Syndrome 1 NGS Genetic DNA Test uses advanced Next Generation Sequencing (NGS) technology to detect changes in the SLC52A3 gene. Mutations in this gene are known to cause Brown-Vialetto-Van Laere syndrome, a rare inherited disorder. This syndrome typically affects the nervous system, often leading to progressive hearing loss and other neurological issues like muscle weakness. This test analyzes a DNA sample to identify specific alterations in the SLC52A3 gene associated with the syndrome. Understanding your genetic predisposition can be crucial for diagnosis, management, and family planning. Genetic counseling is recommended to discuss the results and their implications.

PreparationNo special preparation is usually required for a blood draw. Confirm with the laboratory before booking.
SampleA blood sample (typically 5-10ml in an EDTA tube) or extracted DNA.
MethodologyNext Generation Sequencing (NGS) of the SLC52A3 gene.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test specifically analyzes the SLC52A3 gene. It will not detect mutations in other genes that might cause similar symptoms. A negative result does not completely rule out Brown-Vialetto-Van Laere syndrome if the clinical suspicion is high. Confirm with the laboratory before booking.
