After learning that her daughter, Ginny, was diagnosed with a Peroxisome Biogenesis Disorder-Zellweger Spectrum Disorder (PBD-ZSD), Melissa Bryce Gamble set out to find other parents facing a similar fate.


What she found was a small community of parents corresponding via email and supporting one another as they navigated a lonely diagnosis. Melissa’s desire to raise funds for research, support families and promote awareness of PBD-ZSD led to the formation of the Global Foundation for Peroxisomal Disorders (GFPD) in October of 2010. 

Melissa served as Treasurer of the GFPD from 2010-2015.  She served as President of the GFPD from 2015-2017, overseeing GFPD staff and volunteers in Tulsa, Oklahoma. She now serves as the Executive Director.


Her daughter, Ginny, passed away April 25, 2015, at the age of 6 1/2 from the degenerative effects of PBD-ZSD after a long and valiant battle. Melissa is also a mother to Jack and Avery. Along with her husband, Brant, Melissa strives to honor Ginny's memory through her work with The GFPD and as an advocate for children and adults facing rare diseases.
