ASXL research updates

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.

Ask-a-Researcher: Valerie Arboleda, MD, PhD

Virtual Presentation (December 16, 2021)

Valerie Arboleda, MD, PhD from the University of California Los Angeles presents her team's work, "Multi-omic studies in ASXL syndromes: Deciphering the gene-regulatory role of ASXL gene family" in simple scientific terms. With funding support from the ARRE Foundation, Dr. Arboleda and her team are attempting to establish biomarkers for BOS, which are measurable indicators of disease. This is critical, foundational work that paves the way for being able to test drugs on BOS cells to see if there is improvement at the cellular level. Dr. Arboleda answers questions from participants at the end of the session.
