Bohring-Opitz Syndrome Foundation, Inc.
"The Best Life for All Families Living with BOS"

Clinical & Medical Advisory

Clinical & Medical Advisory Board


The Medical Advisory Board was established to support the foundation and its patients and families.  It serves as a liaison between the BOS Foundation and the medical community.  The role of the board is primarily advisory, however, they may engage in other activities that promote awareness and advocacy on behalf of the Foundation and the community it supports. 

The Medical Advisory Board does not make decisions for the BOS Foundation, however their recommendations, especially those medical in nature, are highly valued.

Members of the Clinical & Medical Advisory Board serve a two-year term that maybe extended up to six consecutive years.

Medical Articles 

A parent with a new BOS diagnosis, or a family member trying to learn more about the disorder can be overwhelmed by the medical literature about BOS. The literature is written in medical jargon and may be hard to understand. We polled our medical advisors for their top selections on the best articles for those new to the syndrome. Here’s what they suggested:

Join the BOS Registry

Patients and families (including angels) with BOS or mutations in ASXL genes are enrolled in our study which is approved by the hospital ethics committees. Parents complete simple questionnaires online about their child’s medical history and may submit photographs as well as test results and notes from their physicians. The information is kept on a secure server. Identified information can only be accessed by the researchers in charge of the study. Deidentified content may be available to other researchers, members of the registry advisory board, and the study participants.
