At Boston Children’s Hospital, we are dedicated to advancing the understanding and treatment of rare diseases. A rare disease affects fewer than 200,000 people. These diseases can be genetic, infectious, or degenerative, and they often present unique challenges in diagnosis and treatment. 

About the CRDC

The Boston Children’s Rare Disease Collaborative (CRDC) was established in 2018 as a hospital-wide research effort. It includes 57 rare disease studies and features the Manton Center for Orphan Disease Research.

The CRDC’s mission is to:

  • Find and understand genetic causes of rare diseases.
  • Facilitate research-informed care.
  • Provide families with genetic diagnoses that enable personalized treatments, including precision medicine and targeted therapies.

Rare diseases we study

Some patients may find that their rare disease does not fit into one specific area. Other patients may have ultra-rare diseases, which affect fewer than one person for every 50,000 people.

Below is a list of rare diseases studied by the CRDC, categorized by medical specialty.
