Melissa Bryce Gamble
Global Foundation for Peroxisomal Disorders
After learning that her daughter, Ginny, was diagnosed with a peroxisome biogenesis disorder-Zellweger spectrum disorder (PBD-ZSD), Melissa 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). Melissa served as Treasurer of the GFPD from 2010-2015, then as Board Chair from 2016-2018. She now serves as executive director of the GFPD, overseeing staff and volunteers in Tulsa, Oklahoma. Her daughter, Ginny, passed away April 25, 2015, at the age of six-and-a-half from the degenerative effects of PBD-ZSD after a long and valiant battle. 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.
