가부키 증후군 시장 - 인사이트, 역학, 시장 예측(2034년)

Key Highlights:

• There are no Kabuki syndrome specific treatments that address the root causes of the syndrome. Current therapies for Kabuki syndrome focus on addressing symptoms as they present in an individual.
• In June 2025, the Kabuki Syndrome Foundation (KSF) has partnered with Unravel Biosciences with an investment of USD 66,500, to identify repurposed drugs that could help treat individuals with a mutation on the KDM6A gene, which can cause Kabuki syndrome type 2. This is the first-ever Kabuki syndrome type 2 drug screen funded by the KSF.
• In May 2025, InnoSer announced a partnership with the KSF to advance preclinical testing of vafidemstat using Kmt2d^+/BGeo mouse models to validate therapeutic potential in Kabuki syndrome.
• In May 2025, the KSF successfully hosted a global clinical management guidelines consensus meeting for Kabuki syndrome. These guidelines will provide standardized, evidence-based recommendations to improve the diagnosis, treatment, and ongoing care of individuals living with this rare genetic disorder. The final management guidelines are expected to be available in 2026.
• The emerging pipeline for Kabuki syndrome remains highly limited, with only one therapy-Vafidemsat, currently in the Phase Ib/II-being developed by Oryzon Genomics.

Kabuki Syndrome Disease Understanding and Treatment Algorithm

Kabuki Syndrome Overview

Kabuki syndrome is a rare inherited genetic syndrome caused by mutations in either the KMT2D or KDM6A gene. These mutations affect methylation, leading to abnormal growth and development. Kabuki syndrome is often recognized by the characteristic facial features that are thought to resemble traditional Japanese Kabuki theatre actors. The condition has a heterogeneous phenotype and affects multiple body systems, leading to craniofacial abnormalities, hearing loss, vision problems, congenital heart defects, feeding difficulties, immune dysfunction, poor growth, skeletal and dermatoglyphic abnormalities, and difficulties with cognition and development.

Kabuki Syndrome Diagnosis

Kabuki syndrome is a challenging clinical diagnosis because many characteristics are absent in the initial neonatal period and may not become evident until later in life. Those with the KMT2D mutation are more likely to have clinical features characteristic of this syndrome in infancy compared to those with a KDM6A mutation. Multiple scoring systems have been developed to diagnose patients with Kabuki syndrome who have not had genetic testing or who have had genetic testing with no identifiable etiology. Genetic testing can be approached in 2 ways. When phenotypic findings suggest a diagnosis of Kabuki syndrome, genetic testing can include either single-gene testing or a multigene panel. Single gene testing with sequence analysis will detect missense, nonsense, splice site variants, and intragenic insertions/deletions. Some specialists recommended that sequence analysis of KMT2D be performed first.

Kabuki Syndrome Treatment

Management requires a lifelong multidisciplinary approach. Regular follow-up by a clinical geneticist, pediatrician, psychologist/psychiatrist, speech therapist, physiotherapist and ophthalmologist will have a major impact. Feeding difficulties may require tube feeding (nasogastric or gastrostomy). Developmental assessments are required in order to tailor medical services to each individual's needs. Other specialists can be required, such as a cardiologist, gastroenterologist, nephrologist, immunologist, ENT (ear, nose and throat) or stomatologist. Special attention is need for fine graphomotor and visuals difficulties.

Kabuki Syndrome Epidemiology

The Kabuki syndrome epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by the total prevalent cases of Kabuki syndrome, total diagnosed prevalent cases of Kabuki syndrome, gender-specific cases of Kabuki syndrome, age-specific cases of Kabuki syndrome, and genetic subtypes-specific cases of Kabuki syndrome in the 7MM market covering the United States, EU4 (Germany, France, Italy, and Spain) and the United Kingdom, and Japan from 2020 to 2034.

• Kabuki syndrome has an estimated frequency of about 1 in 32,000 to 1 in 86,000 individuals.
• Transmission of KDM6A-related Kabuki syndrome is X-linked with males slightly more affected than females.
• The mutations in KMT2D and KDM6A have been found in 56-76% and 5-8% of patients clinically diagnosed with Kabuki syndrome, respectively. In approximately 20% of patients, there is no mutation in either KMT2D or KDM6A.

Kabuki Syndrome Drug Chapters

Vafidemsat: Oryzon Genomics

Vafidemsat is an LSD1 inhibitor developed by Oryzon Genomics. Its efficacy in people with Kabuki syndrome has not yet been determined, but there is data that indicates an LSD1 inhibitor could be a promising treatment candidate for Kabuki syndrome.

• The Kabuki Syndrome Foundation is funding USD 300,000 to test Oryzon's vafidemstat in a Kabuki syndrome mouse model. This mouse study aims to validate the therapeutic potential of vafidemstat and its associated pathway (LSD1), shedding light on a future decision to invest USD 5 million in the first industry-led clinical trial for people with Kabuki syndrome. Results are anticipated later in 2025.
• In their Q1 2025 presentation, the company mentioned that they continue to evaluate the feasibility of a new precision medicine trial in Kabuki Syndrome. The company will decide on a possible submission of an Investigational New Drug (IND) for HOPE trial to the Food and Drug Administration (FDA) in 2025.

Drug Class Insight

With sparse pipeline with only one product in Phase I/II of development, the drug classes currently in for the treatment of Kabuki syndrome encompass LSD1 inhibitor.

Lysine-specific demethylase 1 (LSD1, also known as KDM1A) is a FAD-dependent epigenetic enzyme that removes mono- and di-methyl groups from histone H3 lysine residues (H3K4me1/2 and H3K9me1/2), regulating chromatin accessibility and gene expression. In Kabuki syndrome, disrupted histone methylation is a central pathogenic mechanism, leading to widespread alterations in gene expression essential for normal development and cognitive function. LSD1 plays a role in repressing gene transcription by demethylating active histone marks, and its overactivity can contribute to the epigenetic imbalance seen in Kabuki syndrome. Inhibiting LSD1 can help restore proper histone methylation patterns and gene expression profiles, potentially improving neurodevelopmental outcomes. Preclinical studies have shown that LSD1 inhibition may reverse cognitive and transcriptional deficits in mouse models of Kabuki syndrome by reactivating genes critical for neuronal function and plasticity. Unlike its role in oncology, where LSD1 inhibitors trigger apoptosis or differentiation, in Kabuki syndrome the goal is to normalize gene expression and enhance synaptic and cognitive function. Investigational compounds like ORY-2001 (vafidemstat) are being explored for their ability to modulate epigenetic regulation safely in neurodevelopmental and neuropsychiatric disorders, offering hope for targeted treatment strategies in Kabuki syndrome.

Kabuki Syndrome Market Outlook

The treatment landscape for Kabuki syndrome remains primarily supportive and symptom-based, with no disease-modifying therapies currently approved. This rare neurodevelopmental disorder, typically caused by mutations in the KMT2D or KDM6A genes, results in widespread epigenetic dysregulation that affects growth, cognition, and multiple organ systems. Current management focuses on addressing individual manifestations-such as developmental delays, congenital heart defects, immune dysfunction, and skeletal abnormalities through multidisciplinary care involving speech therapy, physiotherapy, surgical interventions, and educational support. However, these approaches do not address the underlying molecular cause of the disease.

Recent advances in understanding the epigenetic mechanisms driving Kabuki syndrome have sparked interest in targeted therapies aimed at restoring normal gene expression. One promising approach involves inhibition of LSD1 (KDM1A). Preclinical studies have demonstrated that LSD1 inhibitors can rescue cognitive deficits and normalize gene expression in mouse models of Kabuki syndrome. Compounds like vafidemstat (ORY-2001) are being explored for their potential to safely modulate epigenetic regulation in neurodevelopmental disorders. While no therapies have yet received regulatory approval specifically for Kabuki syndrome, early-stage drug development is gaining momentum. As research progresses, investments in targeted epigenetic therapies, such as LSD1 inhibitors, may offer hope for modifying the course of this complex disorder.
