Abstract
<jats:p> Familial advanced sleep phase syndrome (FASPS) is an autosomal dominant circadian rhythm variant; affected individuals are “morning larks” with a 4-hour advance of the sleep, temperature, and melatonin rhythms. Here we report localization of the FASPS gene near the telomere of chromosome 2q. A strong candidate gene (h <jats:italic>Per2</jats:italic> ), a human homolog of the <jats:italic>period</jats:italic> gene in <jats:italic>Drosophila</jats:italic> , maps to the same locus. Affected individuals have a serine to glycine mutation within the casein kinase I <jats:italic>ɛ</jats:italic> (CKI <jats:italic>ɛ</jats:italic> ) binding region of hPER2, which causes hypophosphorylation by CKI <jats:italic>ɛ</jats:italic> in vitro. Thus, a variant in human sleep behavior can be attributed to a missense mutation in a clock component, hPER2, which alters the circadian period. </jats:p>
