MSLT and immunogenetic findings in two unrelated Italian subjects with recurrent monosymptomatic hypersomnia are reported. In both patients MSLT documented a markedly increased daytime sleep propensity during the attacks without augmented REM sleep pressure. Both patients share the same HLA haplotype (HLA‐DR1, DQ1) which has been found in Kleine‐Levin syndrome. This makes these subtypes of recurrent hypersomnia indistinguishable one from the other, under the immunogenetic profile, but permits differentiation from narcolepsy which is HLA‐DR2, DQ1 closely linked.
