About this trial

The Collaboration for Down Syndrome Progress (CDP) is a long-term study that follows people with Down syndrome of all ages. The goal is to better understand their health, development, and everyday experiences over time. Participants and their caregivers will answer questions, share medical information, and may give samples like blood or saliva. Some participants may also take part in optional activities such as sleep studies, movement tracking, or brain imaging. By collecting the same types of information at many sites, the CDP will help researchers learn why certain health conditions are more common in people with Down syndrome and how to improve care and quality of life.

Eligibility criteria

Qualifiers

Individual with Down syndrome

Diagnosis of Down syndrome (with the exception of control participants for the Subsample study on Imaging). We will be enrolling participants with all types of Down syndrome including standard Trisomy 21, mosaic Down syndrome, and translocations.

Primary language is English, Spanish, or Portuguese.

Able to attend in-person or remote visits.

Disqualifiers

A participant will also be excluded if a healthcare professional determines that CDP involvement poses a risk of mental and physical harm to the participant.

Known genetic conditions or syndromes with effects on neurobehavioral development (except for Down syndrome) such as Fragile X syndrome, Williams syndrome, or Prader-Willi syndrome. We may also exclude other syndromes such as Marfan's syndrome or Turner syndrome because of overall significant multisystem effects.

Birth weight < 2,000 grams or gestational age < 34 weeks (infants with Down syndrome infants) or <37 weeks (control subjects)

Significant perinatal adversity, in utero neurotoxin exposure or maternal gestational diabetes requiring medication management
