SUMMARY
Aims: Central disorders of hypersomnolence are lifelong disorders characterized by recurrent episodes of excessive daytime sleepiness. Central disorders of hypersomnolence include narcolepsy (type 1 and type 2) and idiopathic hypersomnia. The pathogenesis of central disorders of hypersomnolence is poorly understood. No effective treatment for the disorders has been established. We expect that genetic researches will provide important contributions to understand the genetic basis and pathogenesis of the disorders. To identify susceptibility genes associated with central disorders of hypersomnolence, we will perform genome-wide association analyses, sequencing analyses and so on for the disorders.
Methods: We performed a genome-wide association study using genotyping data obtained from SNP chip.
Participants/Materials: Idiopathic hypersomnia (13 orexin mutation-positive patients, 116 orexin mutation-negative patients)
