We are currently enrolling participants affected by FASP, FDSP, FNSS, and FNLS into our sleep and circadian studies!

  • FASP: a circadian rhythm trait in which sleep onset occurs in early evening and, as a consequence, wakefulness occurs in early morning.
  • FDSP: a delay of their sleep cycle so that they fall asleep late in the night and wake late in the morning or afternoon.
  • FNSS: a behavioral trait in which they have a lifelong tendency to sleep only 4 – 6 hours per night and feel rested.
  • FNLS: a behavioral trait in which people tend to need around 10 – 12 hours of sleep a night to feel rested.

Participate in a Research Study:

Email our Clinical Coordinator here for details about participating and how to get enrolled in one of our studies!

As an initial screening process, you will be asked to fill out a set of questionnaires. Participants will then sign consent forms detailing the study objectives, UCSF health privacy policy. Once you return the questionnaire and your eligibility is confirmed, a short sleep interview over the phone will be scheduled to discuss in greater detail about your sleeping patterns throughout your life. If we determine you an eligible candidate we then will ask you to donate a blood sample for DNA extraction. A final optional portion may include wearing an actigraphy watch to try and capture objective data on your sleep. We would truly appreciate hearing from you if you feel you have any of these sleep or circadian traits and are interested in participating in our studies.

Participation in our studies is 100% voluntary and participants may withdraw from the study at any time. Maintaining the privacy or our participants’ health information is a top priority. We do not distribute participant information to health insurance agencies or employers. We do not use DNA samples or patient information for revenue-generating purposes. DNA samples and clinical files are used for research purposes only. All data are kept in locked files, cabinets, and on encrypted servers.
