CureGSD1b Team

Advocate Team

Jamas LaFreniere – Founder and President, and Sophie’s Dad

Jamas started Sophie’s Hope Foundation with his wife Margot within months of their youngest daughter Sophie being diagnosed with GSD1b. The foundation’s primary goal is to raise awareness and money to fund research for GSD1b, with a mission to develop a treatment and eventually a cure. Jamas quickly realized that it was critical that the GSD1b community be organized and efficient, thus working to create CureGSd1b as a global GSD1b Patient Advocacy Organization. Jamas is a graduate of Babson College with a BA in Business Management and Entrepreneurship and has spent his entire professional career in technology sales. Jamas’ passion to cure his daughter is the driving force behind Sophie’s Hope Foundation and now CureGSD1b, as well as making him a powerful voice in the rare disease community. Jamas lives with his amazing wife and two beautiful daughters in Massachusetts.

Rabin Pournazarian – Vice President, Jonah’s Dad

Rabin and his wife Lora have been fierce supporters and advocates for GSD1b after their son Jonah was diagnosed in 2006. Over the years they have been a leading fundraiser for GSD1b, which has led to better treatment and major advances in research, specifically in gene therapy. Rabin and his wife Lora have also recently started their own 501c3 called Jonah’s GSD1b Research Foundation, to continue raising money for research. Rabin is a founding member of CureGSD1b with Jamas. The Pournazarian’s reside in sunny California with their 3 children.

Blair Stone-Schneider – Executive Director, Sylvi’s Mom

Blair has been advocating for GSD awareness since their daughter was diagnosed in 2013. Over the years, Blair has become an advocate for GSD1b, rare disease and the undiagnosed. She brings communication and marketing skills to the board, along with a passion for networking throughout rare disease communities worldwide. A graduate of the University of Montana, she spent years as a Senior Consultant to the United States Environmental Protection Agency, with experience in non-profits in both the environmental and health realms. Blair’s mission is to help improve the lives of those with GSD1b, bringing better treatment options to patients as we work towards a cure.

The Stone-Schneider family resides in Helsinki, Finland with their two daughters and two fur babies.

Margot LaFreniere – Board Member, Sophie’s Mom

Margot was instrumental in helping and pushing her husband to start the Sophie’s Hope Foundation and to create a patient advocacy organization for GSD1b. She was even more instrumental in pushing doctors for Sophie’s diagnosis and has been her biggest advocate from day one. Margot graduated from UMass Amherst and is a Registered Nurse at Dana Farber Cancer Institute in Boston, MA. Margot got into nursing to help people and is a fierce advocate for her patients. Her education and career in nursing makes her a huge boost for our organization.

Azra Sehic – Board Member, GSD1b patient

As an adult with GSD1b, Azra’s relationship with this disease is lifelong. Azra was diagnosed with 1b at just 6 months old, as a Balkan war refugee in Germany. At the age of two, German doctors recommended her family move to the United States for better care of this ultra-rare disease. Azra’s life in the United States would eventually lead her to the healthcare field, as a Registered Nurse. Her personal knowledge of life with a chronic disease not only informs the care she provides for patients, but also her work as an advocate for GSD1b. The insight and wisdom that adult patients like Azra bring to the advocate team are an invaluable part of the work Sophie’s Hope Foundation/cureGSD1b does. Azra lives in Atlanta, Georgia.

Stephanie Konieczka – Board Member, Jamie’s Mom

Stephanie and her husband Mark have been supporting GSD1b research and advocating for their daughter Jamie since her diagnosis in 2007 when she was 2 months old. Stephanie is a graduate of University of Iowa and holds a BA in Communications. Early on in her career she worked in marketing, but after Jamie’s diagnosis decided to stay home, and pause her career to provide the best care possible for her daughter, as they navigated the challenges associated with GSD1b. The Konieczka’s reside just outside of Chicago in Hinsdale, IL with their two amazing children and their dog Harley.

Cindy Delano Chen – Board Member, Dylan’s Mom

Cindy and her husband Joe have been long-standing supporters of GSD1b research and have been advocating for Dylan and others with GSD1b since she was diagnosed in 2011. Cindy is currently a co-founder and partner at Invictus Global Management, an investment firm based in Austin, Texas. The Delano’s have also been instrumental in helping fund important studies related to gene therapy for GSD1b. Cindy’s mission is to make a difference in the lives of people like her amazing daughter Dylan, by supporting research and medical advances, so that people born with GSD 1b can benefit from early detection, treatment, and ultimately a cure. The Delano family resides just outside of Austin in Driftwood, Texas.

Maria Veiga-da-Cunha – Scientific Advisor

Maria is a researcher at the de Duve Institute in Brussels, Belgium where her work is focused on the elucidation of inborn errors of metabolism, i.e., diseases due to a genetic defect making that an enzyme of intermediary metabolism is deficient. One of goals is to identify the gene encoding enzymes for which this identity is unknown. Another goal is to identify new enzymes, most particularly metabolite repair enzymes. Of particular importance to GSD1b, Maria has been a part of the team that discovered an SLGT2 Inhibitor (empagliflozin) as a treatment for neutropenia in GSD1b patients. This work has spanned several years, and she continues to dedicate time and effort to continuing this effort. Maria is a terrific resource for the GSD1b team and is always available to answer questions and offer her guidance.
