    Abstract

    Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness, cataplexy, and a pathological manifestation of rapid eye movement during sleep. Narcoleptic pathogenesis is triggered by both genetic and environmental factors. Recently, development of genome-wide association studies (GWAS) has identified new genetic factors, with many more susceptibility genes yet to be elucidated. Using a new approach that consists of a combination of GWAS and an extensive database search for candidate genes, we picked up 202 candidate genes and performed a replication study in 222 narcoleptic patients and 380 controls. Statistical analysis indicated that six genes, NFATC2, SCP2, CACNA1C, TCRA, POLE, and FAM3D, were associated with narcolepsy (P<0.001). Some of these associations were further supported by gene expression analyses and an association study in essential hypersomnia (EHS), CNS hypersonia similar to narcolepsy. This novel approach will be applicable to other GWAS in the search of disease-related susceptibility genes.
