Biomarkers of Central Nervous System Involvement in Pome Disease

Biomarkers of Central Nervous System Involvement in Pome Disease

Title: Biomarkers of Central Nervous System Involvement in Pompe Disease: New Learnings
Date: Thursday, September 24, 2026
Time: 10 a.m. CT / 11 a.m. ET
Speaker:
Kristen Hagarty-Waite, PhD, RDN, LDN

Summary:
Central nervous system (CNS) manifestations persist in patients with Pompe disease, despite enzyme replacement therapy, as current formulations cannot cross the blood brain barrier. Plasma glial fibrillary acidic protein (GFAP) and neurofilament light chain (NfL) have emerged as biomarkers to monitor CNS involvement in Pompe disease, particularly for those with the infantile-onset phenotype. In this presentation, we will share our learnings, so far, regarding biomarkers of CNS involvement.

Reports of Nexviazyme Shipment Delays

Pompe Alliance, Marshall’s Mountain, Grant’s Giants, Pompe Warrior Foundation, Ryan Colburn of the Pompe Community, and the AMDA are working together to help patients obtain clear and timely information regarding reports of Nexviazyme shipment and release delays.

At this time, the delays being reported to our organizations involve some shipments of Nexviazyme. We have not received confirmation that Lumizyme is currently affected, but patients using either treatment may wish to verify their upcoming shipment.

This appears to be a product-release and distribution timing issue — not evidence of a safety or quality problem with medication that has already been released. Patients should not panic or make treatment changes without speaking with their prescribing medical team.

In June 2026, the FDA issued a warning letter following a January inspection of a Sanofi facility in Waterford, Ireland. Sanofi has publicly stated that products released from the facility meet established quality and safety specifications. The FDA warning letter does not specifically identify Nexviazyme or Lumizyme as affected products, and we cannot independently confirm the precise cause of every current shipment delay.

Title: What Do Your Pompe Test Results Really Mean? The Evolution of Pompe Diagnostics: Past, Present, and Future
Date: Thursday, August 20, 2026
Time: 1 p.m. CT / 2 p.m. ET
Speaker:
Deeksha Bali, PhD, FACMG
Summary:
This webinar examines Pompe disease diagnosis in the newborn screening era, drawing on lessons learned since implementation and the growing challenge of novel variants identified each year. It highlights the role of CRIM testing, GAA enzyme and mutation analysis, and urine Hex4 biomarker testing in achieving early, accurate diagnosis. The talk underscores an urgent need for a validated, disease-specific functional assay to characterize variants of unknown significance and support their reclassification, benefiting newly diagnosed patients. It also points to the promise of understanding Pompe disease’s molecular mechanisms to predict disease onset and progression and guide treatment decisions, an unmet need for patients identified through newborn screening.

Mental Health for Pompe Disease: The Importance of Being Understood

Mental Health for Pompe Disease: The Importance of Being Understood

Title: Mental Health for Pompe Disease: The Importance of Being Understood
Date: Thursday, May 14, 2026
Speakers:
Heather Shorten
Nadia Bodkin, Pharm. D., MS
JC Muyl

Summary:
Living with Pompe disease means navigating far more than the physical realities of a complex, progressive condition. The emotional and psychological toll, including the uncertainty, the isolation, and the challenge of finding care that truly sees the whole person, is a dimension of this journey that is too often left unaddressed. This webinar brings together three advocates at the forefront of mental health and rare disease: Heather Shorten of Pompe Alliance, Nadia Bodkin of the Rare Advocacy Movement, and JC Muyl of Mental Health For Rare.

Drawing on community research and lived experience, our presenters will explore the unique emotional challenges tied to living with Pompe disease, why feeling understood matters so deeply, and what meaningful mental health support can look like for this community. Whether you are a patient, caregiver, healthcare provider, or advocate, this is an opportunity to be part of an important and long-overdue conversation about whole-person care in the Pompe disease community.

Summary:
Have you heard about research studies and patient registries for Pompe disease? These studies are a critical tool in capturing the patient experience, which improves disease understanding, management, and treatment options.
Join this session to learn about the different types of research studies and patient registries for Pompe disease. What are the differences between them? How is the data shared and used? We’ll cover what you may want to consider when choosing to participate, cover a few of the historical registries that have contributed to progress in Pompe, and share an innovative patient led registry, Progress4Pompe, where patients own their data and choose how to share it.

Are New Year’s resolutions already starting to feel heavy? Lucas explores why we put so much pressure on ourselves, and why breaking a resolution can spiral into guilt. His gentler reset is simple: pivot to a hobby, and if it does not bring you joy, you can stop without feeling bad about it. He also points to research linking hobby engagement with mental health and well-being.

Grief Happens in Rare Disease: Let’s Talk About it Already

Grief Happens in Rare Disease: Let’s Talk About it Already

Title: Grief Happens in Rare Disease: Let’s Talk About it Already
Date: Thursday, January 15, 2026
Time: 1 PM CST / 2 PM EST
Speaker:
Lisa Keefauver, MSW

Webinar Overview:
Given 100% of us experience loss, multiple times in our lives, means that when we work with humans, we’re working with grievers. That’s why our grief-illiterate culture is deeply problematic, causing so much unnecessary suffering. Based on her professional wisdom as a narrative-therapy trained social worker and her personal insights as a widow and cancer survivor, Keefauver combines metaphor, science, storytelling and humor to help audiences more fully understand the expansiveness and pervasiveness of both the sources and impact of grief in our work and personal lives.
