The BWS Registry was developed to improve our understanding and management of Beckwith-Wiedemann syndrome (BWS), hemihypertrophy/lateralized overgrowth, and other disorders.

The BWS registry involves collecting medical information and records from patients. To join the registry, families complete a consent form to agree to participate. Once a family joins, we assign them a special number and all information collected is stored under this number to protect confidentiality. We study this information to improve our understanding about BWS and how to better manage the disorder. There are other parts of the study (such as sharing pictures and samples) that are optional and families can choose whether to participate in these parts or not.


Thank you for your interest in the BWS Registry!

Families who wish to join the BWS Registry must give us permission (consent) for review of medical records and other optional parts of the study. Optional parts include sharing photographs, samples, and contact preferences. Once a family completes a consent form, each family member will be assigned a unique study number. To protect his/her identity, medical information (and samples as applicable) will be stored with this number. More information about the Registry (Video).

Contact us at [email protected] to discuss your questions.
