Abstract excerpt
Essential hypersomnia (EHS) exhibits excessive daytime sleepiness without cataplexy and is associated with the HLA-DRB1*1501-DQB1*0602 haplotype, similar to narcolepsy with cataplexy. Single-nucleotide polymorphism (SNP) rs1154155 located in the T-cell receptor alpha (TCRA) locus has been recently identified as a novel genetic marker of susceptibility for narcolepsy with cataplexy. We investigated whether the SNP...
