Which Sleep Disorders Can Be Identified Through Genetic Testing?
Several sleep disorders have a genetic component. These include: 1. Narcolepsy: Genetic testing can identify mutations in the HLA-DQB1 gene, which is associated with narcolepsy with cataplexy. 2. Restless Legs Syndrome (RLS): Variants in genes such as MEIS1 and BTBD9 have been linked to RLS. 3. Familial Advanced Sleep Phase Syndrome (FASPS): Mutations in the PER2 and CLOCK genes can lead to this condition. 4. Obstructive Sleep Apnea (OSA): While genetic testing is not commonly used for OSA, research suggests that certain genetic factors may predispose individuals to this disorder.
