The Unseen Threads: When Rare Diseases Run in Families
The story of Hazel Dempster and Lachlan Lindsay, cousins both battling brain tumors, is a stark reminder that sometimes, the improbable happens. While brain tumors aren’t typically considered hereditary, their case highlights a growing area of concern and research: the potential for genetic predispositions to rare diseases, and the evolving landscape of diagnosis and support for families facing these challenges.
The Rising Incidence of Rare Disease Diagnosis
For years, rare diseases – defined as those affecting fewer than 200,000 people in the US – were largely overlooked. However, advancements in genetic testing and increased awareness are leading to more diagnoses. The National Organization for Rare Disorders (NORD) estimates that there are over 7,000 rare diseases, affecting approximately 30 million Americans. This isn’t just a statistical increase; it’s a reflection of improved detection methods.
“We’re seeing a shift,” explains Dr. Emily Carter, a genetic counselor specializing in rare neurological disorders. “Whole-genome sequencing is becoming more accessible and affordable, allowing us to identify genetic variants that might have gone unnoticed previously. This is particularly crucial when multiple family members are affected.”
Beyond “Bad Luck”: Exploring Genetic Links
While Lachlan and Hazel’s doctors currently attribute their diagnoses to “bad luck,” the possibility of a shared genetic vulnerability can’t be dismissed. Even if a specific gene isn’t directly causative, certain genetic variations can increase susceptibility to developing a tumor, or influence how the body responds to treatment. Research into familial cancer syndromes, for example, demonstrates that inherited mutations can significantly elevate risk.
Did you know? Approximately 80% of rare diseases have a genetic component, according to the Genetic and Rare Diseases Information Center (GARD).
The Impact on Mental and Emotional Wellbeing
The emotional toll of a rare disease diagnosis extends far beyond the individual. Families often experience a complex mix of grief, anxiety, and uncertainty. The Dempster and Lindsay families’ story illustrates the unique bond formed through shared adversity. However, it also underscores the need for robust mental health support for both patients and their loved ones.
“There’s a profound sense of isolation that often accompanies a rare disease diagnosis,” says Sarah Miller, a therapist specializing in chronic illness. “Families may struggle to find others who understand their experience, and navigating the healthcare system can be incredibly overwhelming. Support groups and online communities can be invaluable resources.”
Advances in Treatment and Personalized Medicine
The increasing understanding of the genetic basis of rare diseases is paving the way for more targeted and personalized treatments. Gene therapy, for instance, holds immense promise for correcting genetic defects at their source. While still in its early stages, gene therapy has already shown remarkable success in treating certain inherited conditions, such as spinal muscular atrophy.
Pro Tip: If you have a family history of a rare disease, consider genetic counseling. A genetic counselor can assess your risk, discuss testing options, and help you understand the implications of genetic information.
The Role of Technology and Data Sharing
Technology is playing an increasingly important role in rare disease research and management. Patient registries, which collect data on individuals with specific conditions, are crucial for identifying patterns, tracking disease progression, and facilitating clinical trials. Artificial intelligence (AI) is also being used to analyze large datasets and identify potential drug targets.
Data sharing is paramount. Initiatives like the Global Alliance for Rare Disease Master Patient Registries are working to create a collaborative network of registries, enabling researchers to access a wider range of data and accelerate the pace of discovery.
Looking Ahead: A Future of Hope
The journey for individuals like Hazel and Lachlan is ongoing. While their tumors may not be curable, advancements in treatment are helping them manage their symptoms and live fulfilling lives. Their story, and the stories of countless others affected by rare diseases, are driving a wave of innovation and advocacy.

Reader Question: “My child was recently diagnosed with a rare genetic disorder. What steps should I take next?”
Answer: First, connect with a genetic counselor to understand the diagnosis and its implications. Then, seek out support groups and connect with other families facing similar challenges. Finally, explore treatment options and consider participating in research studies.
The future of rare disease research is bright. With continued investment in research, technology, and collaboration, we can move closer to a world where every individual, regardless of their diagnosis, has access to the care and support they need to thrive.
