The Galactosemia Handbook

New Resource for the Galactosemia Community Launches to Empower Families as They Navigate Lifelong Genetic Disease

DOWNLOAD HANDBOOK

The handbook presents information for each life stage of Type 1 galactosemia, with the aim of guiding patients and caregivers from newborn diagnosis through adulthood to help understand the disease lexicon, build a care team and educate their support network on the disease

Created by the Galactosemia Foundation and made possible through support from Jaguar Gene Therapy, the handbook was developed from clinical guidelines, peer-reviewed data, members of the galactosemia community and input from renowned galactosemia experts including physicians, researchers, a metabolic dietician and a speech-language pathologist

ALBANY, N.Y., and LAKE FOREST, Ill., July 25, 2022 – The Galactosemia Foundation, a non-profit charitable organization that advocates for people with galactosemia and their families, and Jaguar Gene Therapy, a biotechnology company accelerating breakthroughs in gene therapy for patients suffering from severe genetic diseases, including those that affect sizeable patient populations, today announced the publication of Navigating Galactosemia Life Stages: A Handbook for the Galactosemia Community. The resource, developed with input from galactosemia experts, provides education and tools to help navigate the significant lifelong challenges of Type 1 galactosemia, a rare genetic disease caused by mutations in the GALT gene that can lead to a severe deficiency in functional GALT enzyme. The handbook was created to support the galactosemia community in managing the many disease complications that can manifest throughout life.

“Type 1 galactosemia can be associated with lifelong cognitive, neurological, speech and fertility complications. For patients and families, this means unique and significant challenges may occur at different stages of life,” said Gerard T. Berry, M.D., Director, Metabolism Program at Boston Children’s Hospital and Professor, Harvard Medical School and leading expert in galactosemia who supported the creation of the handbook. “This new handbook is an important milestone for the galactosemia community because for the first time, patients and families have access to one comprehensive resource with important information on disease management from health care providers, members of the galactosemia community and published research, to help them better understand and navigate all stages of life with Type 1 galactosemia.”

The handbook was developed from clinical guidelines, peer-reviewed data, expert insights and first-hand experience from the galactosemia community. It presents information for each life stage of Type 1 galactosemia, with the aim of guiding patients and caregivers from newborn diagnosis through adulthood to help understand the disease lexicon, build a care team and educate their support network on the disease. The print edition of the handbook will be distributed at the Galactosemia Foundation 2022 Conference, which is taking place July 28-30 in Orlando, and to the families of those newly diagnosed who reach out to the foundation.

“I am incredibly proud of this new resource the Galactosemia Foundation will now be able to offer those living with Type 1 galactosemia and their families,” said Nicole Casale, President of the Galactosemia Foundation. “As with many rare diseases, there has been limited and often fragmented information available on galactosemia, despite our community’s need for these resources. This new handbook will empower individuals and families to better manage Type 1 galactosemia at each life stage.”

About Type 1 Galactosemia

Type 1 galactosemia is a rare genetic disease that can be life-threatening for newborns and cause severe lifelong complications starting as early as the first year of life.1,2,3 Galactosemia affects the body’s ability to make the enzyme that breaks down galactose, a simple sugar the body endogenously produces and is also found in dairy and other foods, including breast milk.1,4,5 Type 1 galactosemia is caused by mutations in the GALT gene that lead to a severe deficiency in functional galactose-1-phosphate uridylyltransferase (GALT) enzyme, which causes a toxic buildup of galactose and its metabolites including Gal-1P and galactitol. This buildup of toxic metabolites is a life-threatening medical emergency in newborns and can contribute to lifelong cognitive, neurological and speech complications, as well as primary ovarian insufficiency in girls and women.1,2,4,5 Because of its severity, galactosemia is part of newborn screening in all 50 states of the United States and in several other countries.1,2,5 No treatments are currently approved for galactosemia, and there is significant unmet medical need. The current standard of care – a galactose-restricted diet – is insufficient because the body endogenously produces galactose, causing patients to experience lifelong complications.2
