Rett Syndrome Global Market Report 2025

The rett syndrome market size has grown strongly in recent years. It will grow from $0.63 billion in 2024 to $0.7 billion in 2025 at a compound annual growth rate (CAGR) of 10.2%. The growth observed during the historic period can be attributed to an increase in clinical trials, heightened awareness among healthcare professionals, the expansion of patient advocacy and support networks, the rising adoption of digital health technologies, and a stronger focus on orphan drug development incentives.

The rett syndrome market size is expected to see strong growth in the next few years. It will grow to $1.02 billion in 2029 at a compound annual growth rate (CAGR) of 9.9%. The anticipated growth in the forecast period is expected to be driven by the increasing prevalence of Rett syndrome, enhanced research funding, rising demand for disease-modifying treatments, greater investment by biotechnology companies, and an expanding pipeline of innovative therapies. Key trends projected for this period include progress in gene therapy, advancements in neuroinflammation research, the integration of artificial intelligence (AI) in drug discovery processes, improvements in symptom management devices, and ongoing developments in the understanding and treatment of the syndrome.

The increasing prevalence of inherited disorders is anticipated to contribute significantly to the growth of the rett syndrome market in the years ahead. Inherited disorders are conditions that result from genetic mutations passed down from parents to their offspring, and include diseases such as cystic fibrosis, sickle cell anemia, hemophilia, and Huntington’s disease. A notable factor contributing to the rise in these conditions is advanced parental age, which heightens the risk of genetic mutations being transmitted to children. Rett syndrome serves as a critical model for understanding inherited disorders by shedding light on the impact of mutations, particularly in the methyl-CpG-binding protein 2 (MECP2) gene. It advances the knowledge of neurodevelopmental mechanisms and supports the exploration of genetically targeted therapies for similar conditions. For example, in 2024, the Perth Blood Institute, an Australian non-profit organization, reported an increase in hemophilia diagnoses from 233,577 individuals in 2021 to 257,146 in 2022. Consequently, the growing prevalence of inherited disorders is propelling the expansion of the rett syndrome market.

Key players in the rett syndrome market are concentrating on the development of innovative treatments, including epigenetic therapies, to address the fundamental genetic causes of the disorder, restore MECP2 function, and potentially alleviate or reverse symptoms. Epigenetic therapies aim to influence gene expression without altering the underlying DNA sequence by targeting mechanisms such as DNA methylation, histone modification, or RNA regulation. For example, in May 2024, Unravel Biosciences Inc., a U.S.-based biotechnology firm, received approval from the U.S. Food and Drug Administration (FDA) for vorinostat (RVL-001) as a potential treatment for Rett syndrome. RVL-001 functions by inhibiting histone deacetylases (HDACs), restoring appropriate gene expression in neurons. This form of epigenetic modulation helps to offset the effects of the MECP2 mutation, with the potential to enhance neurological function.

In December 2024, ProQR Therapeutics N.V., a biotechnology company based in the Netherlands, expanded its partnership with the Rett Syndrome Research Trust (RSRT) to advance RNA editing therapies focused on MECP2 mutations, particularly the R270X mutation, through its Axiomer platform. This collaboration aims to accelerate the development of AX-2402 for entry into clinical trials, offering a promising disease-modifying treatment for Rett syndrome. The Rett Syndrome Research Trust is a U.S.-based nonprofit organization dedicated to supporting and expediting research efforts to find a cure for Rett syndrome.

Rett syndrome is a rare genetic neurological disorder that primarily affects females and leads to significant cognitive and motor impairments. It generally emerges after an initial period of normal development and is caused by mutations in the methyl-CpG binding protein 2 (MECP2) gene, which plays a vital role in brain function. Common symptoms include the loss of purposeful hand use, loss of spoken language, and repetitive behaviors such as hand-wringing.

The primary types of rett syndrome are classic Rett syndrome and atypical Rett syndrome. Classic Rett syndrome is a rare condition that predominantly affects girls and is marked by normal early development followed by a regression in motor and communication abilities due to MECP2 gene mutations. The condition typically progresses through four stages stage I (early onset), stage II (rapid destruction), stage III (plateau), and stage IV (late motor deterioration). Treatment approaches include medications, physical therapy, occupational therapy, speech and language therapy, and other supportive interventions. Diagnosis is commonly confirmed through blood work, genetic testing, and other methods, with care provided in settings such as hospitals, specialty clinics, homecare, and other healthcare facilities.
