Additional Information:

Description: (OMIM) 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).
Clinical Description OMIM Xu et al. (2005) reported a 3-generation family with autosomal dominant transmission of FASPS. Fifteen family members were interviewed for their typical work and vacation sleep-wake schedules, and 5 were identified with FASPS. In the absence of competing ...
Molecular genetics OMIM Xu et al. (2005) identified a thr44-to-ala mutation in the CSNK1D gene (T44A; 600864.0001) that cosegregated with the FASPS phenotype in a 3-generation family.

In affected members of a family with FASPS2, Brennan et al. (2013) ...
