Precision Medicine Service | Children’s Rare Disease Cohorts (CRDC)
Ten million children are affected by a rare disease with a genetic cause. Yet, treatments for rare diseases are limited due to the unique challenges of rare disease research. Pediatric patients affected by the same rare disease (cohorts) are few in number and tend to be geographically widely distributed. So, finding a way to combine small cohorts is extremely valuable.
About the CRDC initiative
The Children's Rare Disease Cohort (CRDC) initiative at Boston Children’s Hospital fuels genomics research (the study of all of a person's genes) around 46 rare disease cohorts to expedite pediatric precision medicine. The information gathered supports our internal and collaborative research projects, and under certain circumstances, the data also can inform clinical treatment of participating families. Enrollment and sample collection can be completed from the comfort of your home.
The CRDC is an institution-wide initiative to better understand the molecular abnormalities associated with rare disease phenotypes. We envision this will allow more rapid diagnosis, in some cases personalized-treatment strategies with current medications, and identification of new targets that will facilitate development of new therapies for children with rare disease.

We have developed a broadly sharable database and have engaged several external partners, including GeneDx, Genuity Science, Emedgene, and Clinithink. Within its first year, the CRDC launched 15 studies of rare pediatric-onset Mendelian diseases, including epilepsy and inflammatory bowel disease (IBD). Together, these studies enrolled 2,441 participants and collected data from medical records and research surveys.

CRDC leadership
The CRDC is led by the CRDC Steering Group (Alan Beggs, PhD; Annapurna Poduri, MD, MPH; Janet Chou, MD; Piotr Sliz, PhD; and Shira Rockowitz, PhD) that is guided by a Scientific Advisory Board (Heidi Rehm, PhD, FACMG; Michael Talkowski, PhD; Robert Gentleman, PhD; Christopher Walsh, MD, PhD; Ingrid Holm, MD, MPH; Elizabeth Engle, MD; David Williams, MD). The cohort selection process is led by Timothy Yu, MD. PhD; Leonard Rappaport, MD, MS; Siddharth Srivastava, MD; Margaret Kenna, MD, MPH, FACS, FAAP; and Olaf Bodamer, MD, PhD, FACMG, FAAP, and includes all CRDC faculty members. The CRDC is implemented by Research Computing under the direction of Shira Rockowitz, PhD; and Piotr Sliz, PhD. As of today, 46 rare disease cohorts have been approved to join the CRDC. The table below lists the participating clinicians, their contact information, and area of interest for projects that are operational with IRB protocols in place.
