Jacqueline Zarro, PhD

Board secretary, Philadelphia, PA

As a volunteer patient, Dr. Zarro had been an active member of the VHL Alliance community before joining the Board in 2023. In her advocacy work to date, Jacqueline has been committed to pursuing federal research funding and served as co-chair of the inaugural VHLA Federal Advocacy Committee. She is also a representative of the VHL community on research protocols and to other organizations and groups who champion kidney cancer research, neuroendocrine research, urologic cancers, the Congressionally Directed Medical Research Program, and rare diseases overall. Further, through her advocacy work, she is committed to raising the awareness of diversity and inclusion and calling to attention the significant disparities in healthcare and survival outcomes.

Diagnosed at the age of 44, she has many VHL manifestations and has undergone a variety of extensive treatments just like so many others. She believes that every member of the VHL community has an extraordinary power to advocate and encourages individuals to do what they are able. This belief is rooted in the fact that discoveries over decades of research of VHL gene have recently proven extraordinarily fruitful and that this knowledge will continue to benefit our VHL community along with many other medical conditions, as well.

This has resulted in a more comprehensive approach to treatment, at another level, which would not have been possible without the Alliance.

The VHLA provided not only the lifesaving information we needed to begin to understand how to manage my daughter’s care, but they embraced us with community. I was and am so impressed with the formation of the critically important Clinical Care Centers across the United States and to have connected with Nancy Rose’s outstanding VHL team at the Moffitt Center in Tampa. The young adult get-togethers and the annual family conferences, the Facebook group, and the educational interviews with leading researchers in the field have been outstanding resources in advancing the support for both the patients and their families. I am indebted to the VHL Alliance.”
