Cell and Gene Therapies in Rare Disorders Insights and Trends
- Rare diseases, defined as conditions affecting fewer than 1 in 2,000 people, are not truly rare when viewed collectively. More than 6,000 rare diseases have been identified, impacting approximately 300 million people worldwide, representing nearly 3.5-5.9% of the global population.
- The European Commission defines rare diseases as chronic or life-threatening conditions that impact fewer than 1 in 2,000 individuals, equivalent to approximately 50 per 100,000 people.
- Approximately 80% of rare diseases have a genetic origin.
- About 70% of these diseases manifest during childhood, highlighting the importance of early diagnosis and intervention.
- The prevalence of X-linked retinitis pigmentosa (XLRP) was estimated to be between 2.7-3.5 per 100,000 males in the US and Europe. After correction for misclassification, the prevalence increased to 4.0-5.2 per 100,000 males. Finally, the proportion of XLRP cases due to RPGR mutations was applied, resulting in an RPGR-mutated XLRP estimate of 3.4-4.4 per 100,000 males.

Cell and Gene Therapies in Rare Disorders: Understanding
Cell and Gene Therapies in Rare Disorders Overview
Cell and gene therapies represent a rapidly advancing class of treatments designed to address the underlying genetic causes of rare disorders rather than managing symptoms alone. These therapies aim to correct, replace, or modify defective genes or cellular functions, offering the potential for long-term or curative outcomes in diseases with high unmet need. Rare disorders collectively affect a large global population, despite each condition being individually uncommon. Many of these diseases are driven by single-gene mutations or well-defined molecular defects, making them well-suited for targeted genetic interventions. Advances in viral vectors, gene editing platforms (such as CRISPR-based technologies), and cell engineering techniques have significantly accelerated therapeutic development in this space. Cell therapies typically involve the modification or replacement of diseased cells, while gene therapies focus on delivering functional genes or correcting genetic mutations in vivo or ex vivo. Together, these approaches are transforming the treatment landscape by shifting care from chronic disease management to one-time or durable therapeutic interventions.
Rare Disorders Diagnosis
Diagnosis of rare disorders often involves a complex and lengthy process due to the heterogeneous nature of symptoms and limited disease awareness. It typically begins with clinical evaluation and patient history, followed by targeted laboratory tests and imaging based on presenting features.
Definitive diagnosis is increasingly supported by genetic testing techniques such as next-generation sequencing (NGS), whole exome sequencing (WES), and whole genome sequencing (WGS), which help identify underlying gene mutations or molecular defects. Early and accurate diagnosis is critical for enabling timely intervention, including eligibility for cell and gene therapies in applicable cases.
