Advanced sleep phase syndrome is characterized by very early sleep onset and offset (summary by Jones et al., 1999). For a discussion of genetic heterogeneity of advanced sleep phase syndrome, see FASPS1 (604348). [from OMIM]

Advanced sleep phase syndrome is characterized by very early sleep onset and offset (summary by Jones et al., 1999). Genetic Heterogeneity of Advanced Sleep Phase Syndrome See also FASPS2 (615224), caused by mutation in the CSNK1D gene (600864) on chromosome 17q25, and FASPS3 (616882), caused by mutation in the PER3 gene (603427) on chromosome 1p36. [from OMIM]

Advanced sleep phase syndrome is characterized by early sleep time (sleep onset) and early morning awakening (sleep offset) (summary by Zhang et al., 2016). For a discussion of genetic heterogeneity of advanced sleep phase syndrome, see FASPS1 (604348). [from OMIM]

Familial advanced sleep phase syndrome-4 (FASPS4) is an autosomal dominant condition in which individuals wake and sleep early (summary by Kurien et al., 2019). For a discussion of genetic heterogeneity of advanced sleep phase syndrome, see FASPS1 (604348). [from OMIM]
