Narcolepsy Risk DNA Test

Narcolepsy Risk DNA Test – Detect the HLA-DQB1*06:02 Genetic Variant

The Narcolepsy Risk DNA Test is designed to detect the presence of the HLA-DQB1*06:02 allele, which is strongly associated with narcolepsy — a chronic sleep disorder characterized by overwhelming daytime drowsiness and sudden attacks of sleep. If you struggle to stay awake during the day despite a full night's sleep, this test may provide the answers you need.

• Detects the HLA-DQB1*06:02 variant associated with narcolepsy
• Carriers of two copies of the allele have a 7x to 25x increased risk of developing narcolepsy
• 100% private and confidential online results
• Simple and painless mouth swab sample collection

What Is Narcolepsy?

Narcolepsy is a sleep disorder that affects the brain's ability to regulate sleep-wake cycles. Symptoms include excessive daytime sleepiness, sleep paralysis, hallucinations, and in some cases, cataplexy — sudden, brief loss of muscle tone. It affects approximately 1 in 2,000 to 1 in 5,000 individuals, yet only about 25% receive an accurate diagnosis. Family members of affected individuals have a substantially increased risk, up to 20–40 times higher than the general population.

The Genetics Behind the Narcolepsy Risk DNA Test

The Narcolepsy Risk DNA Test identifies the presence of the HLA-DQB1*06:02 allele, which is present in approximately 90–99% of individuals with narcolepsy. This allele is part of the human leukocyte antigen (HLA) system, crucial for the immune system's ability to distinguish between self and non-self molecules.

• Two copies of HLA-DQB1*06:02 puts you at 7 to 25 times higher risk
• One copy of HLA-DQB1*06:02 along with another gene variant increases risk by 3 times
• No copies of HLA-DQB1*06:02 indicates a lower risk of narcolepsy

Not all individuals with this allele develop narcolepsy — other genetic and environmental factors also play a role.

Symptoms of Narcolepsy

• Excessive daytime sleepiness, making it difficult to concentrate and stay awake
• Cataplexy — temporary loss of muscle control, often triggered by emotions such as laughter or anger
• Sleep paralysis — temporary inability to move or speak when waking up or falling asleep
• Microsleeps — brief episodes of sleep that can occur at any time
• Memory problems, headaches, and restless sleep including vivid nightmares
• Hallucinations, particularly when going to sleep or waking up
• Waking up frequently throughout the night or having trouble staying asleep

Frequently Asked Questions

Does a positive result mean I have narcolepsy?
Not necessarily. Carrying the HLA-DQB1*06:02 allele significantly increases your genetic risk but does not confirm a diagnosis. Many carriers never develop narcolepsy. A positive result should be discussed with a sleep specialist or neurologist who may recommend a polysomnography (sleep study) for further evaluation.

Who should consider this test?
This test is recommended for individuals experiencing unexplained excessive daytime sleepiness, sudden muscle weakness triggered by emotions, sleep paralysis, or hallucinations at sleep onset. It is also valuable for those with a family history of narcolepsy.

Do I need to stop any medications before testing?
No. This test analyzes your DNA, not medication levels or sleep hormones. You can collect your sample at any time regardless of current medications or sleep patterns.

How is the sample collected and how long until results?
DNA is collected using a painless buccal (cheek) swab — simply rub it inside your mouth for 15 seconds. Results are delivered securely online within 1–3 business days after the laboratory receives your sample.
