Narcolepsy Risk DNA Test
Struggling to stay awake during the day? Narcolepsy disrupts sleep-wake cycles, leading to excessive daytime sleepiness. This DNA test detects the HLA-DQB106:02 variant, which increases the risk—by 7x to 25x in those with two copies. Find out if your symptoms may be genetic.
What does it measure:
- Simple at-home sample collection
- Non-invasive mouth swab
- Secure online results

Test Description
Narcolepsy is a neurological disorder that causes excessive daytime sleepiness and sudden sleep episodes. It affects about 1 in 2,000 to 1 in 5,000 people, but many cases go undiagnosed or are mistaken for other conditions.
This test detects the HLA-DQB106:02* allele, a key genetic risk factor for narcolepsy. People with two copies of this variant have a 7x to 25x higher risk, and family members of those affected face a 20x to 40x increased risk.
While this test alone cannot diagnose narcolepsy, it helps assess genetic risk and can support a more accurate diagnosis when combined with clinical evaluation.
