Introduction to ASXL-related disorders
Virtual presentation (August 23, 2021)
Vishnu Cuddapah, MD from the Children's Hospital of Philadelphia explains the genetic basics of ASXL-related disorders including what the ASXL genes are, what they do, and how changes to the ASXL genes can result in Bohring-Opitz Syndrome, Shashi-Pena Syndrome, or Bainbridge-Ropers Syndrome.

ASXL-related disorders introduction
Published symptoms and clinical features
The ARRE Foundation cataloged a list of all the symptoms reported in the medical literature about individuals with each ASXL-related disorder. This chart of symptoms across health domains is available in a downloadable PDF and is a helpful document to share with your loved one’s doctors.
It’s important to note that all the symptoms listed here are not present in every individual. This is a wide range of symptoms reported across multiple individuals who have varying severity of their condition. The intent of this document is to help you and your loved one’s doctors know what signs and symptoms to watch for.

Finding answers through research
Awareness campaign (November 22, 2022)
What if your loved one had a genetic disorder so rare that no one had ever heard of it before -- let alone knew how to treat it? For many families with Bohring-Opitz Syndrome, Shashi-Pena Syndrome, and Bainbridge-Ropers Syndrome, this is their reality. The ASXL Rare Research Endowment Foundation is trying to change that. Your contribution helps support research and education that improves the quality of life for families living with an ASXL syndrome. From research grants for scientists to educational events for families, your gift to the ARRE Foundation is supporting a brighter future full of knowledge and hope.

Research update: DNA methylation patterns associated with Bohring-Opitz Syndrome
Virtual research update (April 5, 2022)
In April 2022, a collaborative team from the Hospital for SickKids and the University of California Los Angeles published a paper in the European Journal of Human Genetics titled, "DNA methylation signature associated with Bohring-Opitz syndrome: a new tool for functional classification of variants in ASXL genes." In this video, lead researcher Zain Awamleh, PhD explains what a DNA methylation pattern is and that the research team found a distinctive pattern associated with Bohring-Opitz Syndrome. This pattern can be used to improve diagnoses and can be used as a biomarker, or measurement tool, to test the effectiveness of future therapies. This work was funded in part by the ARRE Foundation with contributions from families living with ASXL syndromes. We thank all of the families who have contributed to research, both financially and by providing biological samples to make this work possible.
