Kabuki Syndrome

Kabuki syndrome is a rare genetic condition present from birth. It affects how a child’s face, body, brain, and several organs develop and work. The name comes from the special look of the eyes and eyebrows that, in many children, resembles the make‑up used by actors in traditional Japanese Kabuki theatre. The condition is lifelong, but the exact mix and severity of problems can vary a lot from one person to another. There is no single “cure,” but there are many helpful treatments and supports.

Kabuki syndrome is a rare genetic condition that affects many parts of the body. It often causes a recognizable facial appearance (arched eyebrows, long eye openings with the outer lower lid turned out, large earlobes), short stature, low muscle tone in infancy, feeding difficulties, hearing problems, heart or kidney differences, joint laxity, and learning or developmental challenges. Doctors make the diagnosis by looking at the pattern of features and confirming it with genetic testing. Most people with Kabuki syndrome have a change in a gene called KMT2D (also known as KS type 1), and a smaller group have a change in KDM6A (KS type 2). These genes help cells turn other genes “on” at the right time, so changes can disrupt development in many organs. Many cases happen de novo (a brand-new change in the child), but Kabuki can be inherited (KMT2D = autosomal dominant; KDM6A = X-linked). NCBIMedlinePlusRare DiseasesGenomics Education Programme

Types of Kabuki Syndrome

Doctors often use “types” based on which gene is affected. This helps with genetic counseling and sometimes hints at patterns of symptoms, though both types overlap a lot.

Type 1 (KABUK1)

• Caused by a harmful change in KMT2D on chromosome 12.
• Inheritance pattern is usually autosomal dominant. This means one changed copy of the gene is enough to cause the condition. Most cases happen de novo (a new change in the child), but sometimes a parent with Kabuki syndrome passes it on.

Type 2 (KABUK2)

• Caused by a harmful change in KDM6A on the X chromosome.
• Inheritance pattern is usually X‑linked dominant. This means the gene is on the X chromosome. Males (with one X) and females (with two Xs) can both be affected, but the pattern in families may look different from Type 1.

Mosaic Kabuki Syndrome (any type)

• In some people, the genetic change is present in only a portion of cells (mosaicism). This can make features milder or more uneven across organs.

Clinically Diagnosed (gene‑negative) Kabuki Syndrome

• A small number of people have a classic clinical picture but no change is found in KMT2D or KDM6A with standard tests. Some may have very rare changes near these genes, deep within introns, or in other genes that control similar chromatin pathways. As genetic testing improves, more of these cases get solved.

Causes

“Cause” here does not mean lifestyle or pregnancy exposures. For Kabuki syndrome the causes are genetic and molecular. Below are 20 ways the two core genes or their control systems can be disrupted. Each item is explained in simple language.

1. Loss‑of‑function variants in KMT2D (nonsense) – A single‑letter DNA change creates a premature “stop” signal, so the KMT2D protein is too short to work.
2. Frameshift variants in KMT2D – Small insertions or deletions shift the reading frame of the gene, again producing a broken protein.
3. Splice‑site variants in KMT2D – DNA changes at the borders of exons and introns cause incorrect editing of the RNA message, so exons may be skipped or introns kept, damaging the protein.
4. Missense variants in crucial KMT2D domains – One amino acid swaps for another inside a key working part (such as the SET domain) and the enzyme’s methyltransferase activity is weakened or lost.
5. Large deletions/duplications affecting KMT2D – A chunk of the gene or nearby control DNA is missing or duplicated, preventing normal KMT2D production.
6. Chromosomal rearrangements disrupting KMT2D – Pieces of chromosomes break and rejoin in new ways (translocations/inversions), splitting the gene or moving it away from its controls.
7. Loss‑of‑function variants in KDM6A (nonsense/frameshift) – Similar to KMT2D, a premature stop or frameshift harms the KDM6A protein.
8. Missense variants in KDM6A JmjC catalytic domain – A key amino acid change blocks the enzyme’s ability to remove specific chemical marks (demethylation) from histones.
9. Exon‑level deletions/duplications in KDM6A – Missing or extra exons distort the KDM6A message.
10. Regulatory (promoter/enhancer) variants – Subtle changes in DNA switches near KMT2D or KDM6A lower gene activity even if the coding sequence looks normal.
11. Deep intronic variants creating cryptic splice sites – Hidden changes deep within introns make the cell splice the message wrongly.
12. Mosaicism for KMT2D or KDM6A variants – Only some cells carry the change. The proportion of affected cells can shape symptom severity.
13. De novo (new) variants – The change arises for the first time in the child; neither parent has it in their blood cells. This is common in Kabuki syndrome.
14. Inherited variants from an affected parent – Less common, but if a parent has Kabuki syndrome (sometimes mildly), the variant can be passed to children.
15. Skewed X‑inactivation affecting KDM6A in females – In females with two X chromosomes, the body randomly inactivates one X in each cell. If the healthy X is inactivated more often, symptoms may be more pronounced.
16. Epigenetic imbalance of H3K4 methylation (KMT2D pathway) – KMT2D normally adds “open‑for‑business” marks (H3K4 methylation) to chromatin. When it is weak or absent, many developmental genes are not switched on properly.
17. Epigenetic imbalance of H3K27 demethylation (KDM6A pathway) – KDM6A removes “closed” marks (H3K27me3). Without it, chromatin stays too closed and genes that should be active remain silent.
18. Disrupted enhancer function during organ development – Enhancers are long‑range gene switches. KMT2D and KDM6A help enhancers work. Faulty enhancer activity during fetal life alters the blueprint for face, heart, brain, kidneys, and immune system.
19. Modifier genes – Other genes in the same chromatin network may “dial up or down” the impact of the main variant, partly explaining why severity varies widely.
20. Unidentified/unsolved genetic causes (currently gene‑negative cases) – Some individuals have a Kabuki‑like pattern without a detectable change in the known genes using standard tests. Ongoing research continues to discover rare or cryptic causes.

Important note: There is no proven environmental, diet, or pregnancy‑related cause that parents can control to prevent Kabuki syndrome. Nothing a parent did or did not do causes these genetic changes.

Common Symptoms and Signs

Every person is unique. Some children have only a few features; others have many. The following are among the most commonly reported. Each is described in plain English.

1. Distinctive facial features – Long openings of the eyelids (long palpebral fissures), the outer third of the lower lid turns outward (eversion), arched eyebrows with notches or sparse outer ends, a broad, flat nasal tip, and large, prominent ear lobes.
2. Postnatal growth restriction and short stature – Babies may be average size at birth but grow more slowly afterward, leading to shorter height than peers.
3. Developmental delay and learning differences – Milestones (sitting, crawling, walking, talking) may be late. School‑age children can have mild to moderate intellectual disability or specific learning issues.
4. Low muscle tone (hypotonia) – Babies feel “floppy,” which can delay motor milestones and make feeding harder.
5. Feeding difficulties and poor weight gain (failure to thrive) – Weak suck, reflux, or a cleft palate can make feeding slow; some children need temporary feeding tubes.
6. Cleft palate or submucous cleft – An opening or thin area in the palate can cause nasal speech and ear problems.
7. Recurrent ear infections and hearing loss – Fluid behind the eardrum, narrow ear canals, or middle ear differences can reduce hearing; some children need ear tubes or hearing aids.
8. Congenital heart defects – Problems such as septal defects (holes in the heart), coarctation of the aorta, or other anomalies can be present and may require monitoring or surgery.
9. Skeletal differences – Joint laxity (loose joints), scoliosis (spine curve), hip dislocation, short fingers, or persistent fetal finger pads.
10. Kidney and urinary tract anomalies – Missing, small, or oddly shaped kidneys, reflux of urine, or other differences that raise the risk of infections.
11. Dental and oral anomalies – Crowded teeth, wide spacing, small teeth, deep grooves, frequent cavities, and high‑arched palate.
12. Eye and vision issues – Strabismus (misaligned eyes), droopy eyelids, long eyelashes, refractive errors; some have coloboma (a missing piece of eye tissue).
13. Immune dysfunction – More frequent infections; some have low immunoglobulin levels (antibodies) and may benefit from vaccines on schedule and, at times, immune‑globulin therapy.
14. Endocrine issues – Growth hormone deficiency, early or delayed puberty, or thyroid problems can occur in some children.
15. Neurologic issues – Seizures in a subset; differences on brain MRI in some; coordination or fine‑motor difficulties are common.

Other features, less universal but reported, include sleep apnea, constipation, hernias, behavioral traits of autism spectrum disorder, anxiety, and attention challenges.

How Is Kabuki Syndrome Diagnosed

Diagnosis starts with a careful clinical exam by a clinician who knows the syndrome, followed by genetic testing. Additional tests are used to map each child’s needs and to guide care. Below are 20 commonly used tests, grouped for clarity. Not every child needs every test—doctors tailor the work‑up to the person.

A) Physical Examination

1. Full dysmorphology exam – A head‑to‑toe look for typical facial traits, ear shape, palate, skin creases (fetal finger pads), and body proportions.
2. Growth assessment – Measuring length/height, weight, and head circumference and plotting them on growth charts over time to document postnatal growth pattern.
3. Cardiac exam – Listening for heart murmurs or abnormal pulses that might suggest a heart defect.
4. Musculoskeletal and neurologic exam – Checking joint range, spine curvature, hip stability, muscle tone, reflexes, and coordination.
5. ENT and oral exam – Looking for cleft or submucous cleft palate, crowded teeth, high‑arched palate, or signs of ear fluid.

B) Manual/Bedside Tests

6. Beighton score for joint hypermobility – A simple series of stretches to see how flexible the joints are.
7. Cover–uncover and Hirschberg tests for strabismus – Quick bedside checks for eye alignment.
8. Bedside feeding/swallow assessment – Observation of suck, swallow, and breathing coordination during feeds.

C) Laboratory & Pathology

9. Targeted genetic testing of KMT2D and KDM6A – DNA sequencing to look for disease‑causing variants.
10. Deletion/duplication analysis (CNV testing/MLPA) – Detects missing or extra pieces of these genes not seen by standard sequencing.
11. Clinical exome or genome sequencing – A broader test that can find changes missed by targeted tests and help solve gene‑negative cases.
12. Immunologic work‑up – Complete blood count, immunoglobulin levels (IgG, IgA, IgM), and lymphocyte subsets to evaluate infection risk.
13. Endocrine studies – Thyroid function tests (TSH, free T4), growth hormone testing (screening IGF‑1/IGFBP‑3, and GH stimulation when indicated), and puberty hormones as needed.
14. Renal and metabolic labs – Creatinine, electrolytes, urinalysis, and targeted metabolic labs based on symptoms.

D) Electrodiagnostic Tests

15. Electrocardiogram (ECG) – A painless tracing of the heart’s electrical activity to screen for rhythm issues or chamber stress.
16. Electroencephalogram (EEG) – Measures brain waves to evaluate seizures or unusual staring spells.
17. Auditory brainstem response (ABR) – Uses sound clicks and scalp sensors to check hearing when a child is too young for reliable behavioral testing.

E) Imaging Tests

18. Echocardiogram (heart ultrasound) – Looks for structural heart defects.
19. Renal ultrasound – Checks kidney size, shape, and drainage.
20. Brain MRI – Evaluates brain structure if seizures, tone differences, or developmental concerns suggest it would help.

Medication options

There is no disease-specific drug approved for Kabuki syndrome. Medicines treat specific problems. Doses below are typical ranges (not medical advice). Prescribers adjust to age, weight, diagnosis, and monitoring needs.

1. Somatropin (recombinant human Growth Hormone, rhGH) — endocrine therapy
   Typical pediatric dose: ~0.035 mg/kg once daily (≈1.0 mg/m²/day), usually at night.
   Why/when: Documented GH deficiency or significant short stature after endocrine evaluation.
   How it works: Replaces GH to stimulate growth plates via IGF-1.
   Key points/side effects: Monitor IGF-1, glucose, scoliosis progression, headaches (rare pseudotumor cerebri), hip pain (SCFE). Studies in children with Kabuki show catch-up growth during treatment. PubMedKarger

2. Levothyroxine — thyroid replacement
   Typical pediatric dose: ~1–4 mcg/kg/day depending on age (higher in infants, lower in teens/adults).
   Why/when: Treats hypothyroidism if present.
   How it works: Replaces T4 to normalize metabolism and growth.
   Key points: Dose guided by TSH/T4 labs; over- or under-treatment affects growth and behavior. NCBI

3. Levetiracetam — antiepileptic
   Typical pediatric dose: 20–60 mg/kg/day divided twice daily.
   Why/when: Seizures.
   How it works: Modulates synaptic neurotransmission; broad-spectrum.

4. Omeprazole (or another PPI) — anti-reflux
   Typical pediatric dose: ~0.7–3.3 mg/kg/day (formulation- and age-specific; often 1 mg/kg/day).
   Why/when: Significant gastroesophageal reflux affecting feeding, growth, or airway.
   How it works: Reduces stomach acid to ease pain and protect the esophagus.
   Key points: Use alongside feeding/positioning strategies; review need periodically. NCBI

5. Amoxicillin-clavulanate (prophylaxis in select cases) — infection prevention
   Typical pediatric prophylaxis: low-dose daily or once nightly regimens vary; clinician-guided.
   Why/when: For recurrent bacterial infections when immunology recommends it.
   How it works: Suppresses common bacterial pathogens in ENT/airways.
   Key points: Consider risks (resistance, GI upset); use only when clearly indicated. PMC

6. Immunoglobulin replacement (IVIG or SCIG) — biologic therapy
   Typical dose: ~0.4–0.6 g/kg monthly (IVIG) or equivalent weekly/biweekly (SCIG).
   Why/when: Documented antibody deficiency with recurrent/severe infections.
   How it works: Provides the protective antibodies the body lacks.
   Key points: Reduces infections; monitor for infusion reactions; long-term therapy in many. primaryimmune.orgPubMed

Dietary, molecular, and supportive supplements

No supplement has been proven to “treat” Kabuki syndrome itself. Use supplements only when there’s a deficiency or a clear target symptom, and always coordinate with your clinician/dietitian.

1. Vitamin D3 – supports bone health; typical pediatric maintenance often 400–1000 IU/day (higher if deficient per labs).
   Why/how: Enhances calcium absorption; prevents deficiency in kids with limited intake or low sun exposure.

2. Calcium – amount depends on age/diet; aim to meet daily recommended intake through food first.
   Why/how: Works with vitamin D to build bone.

3. Iron – dose per lab-confirmed deficiency (e.g., 3–6 mg/kg/day elemental iron in children).
   Why/how: Corrects iron-deficiency anemia that can worsen fatigue and cognition.

4. Omega-3 (fish oil or algal DHA/EPA) – typical pediatric range per label/clinician.
   Why/how: May support triglyceride control and general brain health; evidence for neurodevelopment varies.

5. Probiotics – strains and doses vary.
   Why/how: May help antibiotic-associated diarrhea or constipation for some; quality matters.

6. Fiber (psyllium/inulin or food-based) – titrate slowly with water.
   Why/how: Eases constipation common in hypotonia and low activity.

7. Zinc – only if low intake/deficiency.
   Why/how: Supports immune function and healing.

8. Magnesium – helpful for constipation (magnesium hydroxide/citrate) per clinician guidance.
   Why/how: Draws water into stool; also a cofactor for many enzymes.

9. Multivitamin – fills small gaps when appetite is limited.
   Why/how: Safety net; not a substitute for a varied diet.

10. Vitamin B12 and folate – only with dietary restriction or lab-proven deficiency.
    Why/how: Support red-blood-cell and nerve health.

11. Coenzyme Q10 – sometimes used for fatigue; evidence limited. Use only with clinician input.

12. L-carnitine – sometimes considered for low muscle tone/fatigue; evidence mixed; check labs and medications.

13. Electrolyte solutions (for illness) – to prevent dehydration during vomiting/diarrhea.

14. Medium-chain triglyceride (MCT) oil – small amounts can boost calories in poor appetite; monitor tolerance.

15. Thickening agents (for dysphagia) – not a nutrient, but an important feeding aid to reduce aspiration risk when recommended after a swallow study.

(These are general pediatric practices rather than Kabuki-specific cures; discuss each choice with your care team.) NCBI

Regenerative, and stem-cell–type therapies

• What’s available now: For people with antibody deficiency, immunoglobulin replacement (IVIG/SCIG) is a proven therapy that reduces infections. In some cases with frequent infections, specialists may recommend targeted antibiotic prophylaxis. There is no approved stem cell or gene therapy for Kabuki syndrome itself. primaryimmune.orgPubMedPMC

• What’s in research (preclinical):

  • Histone deacetylase (HDAC) inhibitors (e.g., AR-42) rescued memory and neurogenesis in mouse models by re-opening chromatin and restoring gene activity patterns.

  • LSD1/KDM1A inhibitors (e.g., TAK-418) also rescued adult neurogenesis and memory in mouse models.

  • A ketogenic diet improved hippocampal memory and neurogenesis in mouse models, possibly via epigenetic effects of ketone bodies.

  • Patient-advocacy groups are funding additional animal studies (e.g., vafidemstat) to explore epigenetic modulation.
    These are not yet approved human treatments for Kabuki; clinical trials will be needed to test safety and benefit. PMC+1NatureCellPubMedPNASkabukisyndromefoundation.org

Surgeries

1. Cleft palate repair / VPI surgery (e.g., pharyngeal flap or sphincter pharyngoplasty)
   Why: Improve speech and prevent nasal regurgitation. When: Typically in early childhood; timing individualized. NCBI

2. Ear tubes (tympanostomy)
   Why: Drain chronic middle-ear fluid; reduce infections; protect hearing for speech development. When: Recurrent or persistent effusions despite medical management. NCBI

3. Congenital heart defect repair
   Why: Correct structural heart problems (e.g., septal defects, valve issues) to improve circulation and growth. When: As determined by cardiology and cardiac surgery teams. NCBI

4. Orchiopexy (undescended testis)
   Why: Protect fertility and reduce torsion/cancer risk. When: Usually before 1–2 years of age, if needed. NCBI

5. Spinal surgery for scoliosis
   Why: Prevent progression and improve posture/breathing when curves are severe or worsening. When: After orthopedic evaluation and bracing trials if appropriate. NCBI

Practical prevention strategies

Because Kabuki syndrome is genetic, you cannot prevent the condition itself after conception. But you can prevent complications and plan wisely:

1. Genetic counseling for families (recurrence risk, prenatal and preimplantation options if a familial variant is known). NCBI

2. Stay current on vaccines (with immunology input if antibody deficiency is present). primaryimmune.org

3. Hearing surveillance and early interventions to prevent speech and learning setbacks. NCBI

4. Dental hygiene and regular dental/orthodontic care to prevent caries and alignment problems. NCBI

5. Growth and nutrition monitoring to prevent faltering growth and micronutrient deficiencies. NCBI

6. Prompt treatment of ear/sinus/chest infections to prevent complications. NCBI

7. Sleep screening for snoring/apnea to prevent daytime behavior and learning issues. NCBI

8. Orthopedic follow-up for scoliosis and hypermobility to prevent pain and deformity. NCBI

9. Safety plan for seizures if present (rescue meds, supervision during water activities). NCBI

10. Care coordination & resources (e.g., Kabuki Syndrome Foundation) to reduce gaps in care. kabukisyndromefoundation.org

---

When to see a doctor urgently

• Blue spells, chest pain, fainting, or trouble breathing.

• Signs of severe infection (very high fever, lethargy, breathing difficulty, dehydration).

• New seizures or prolonged seizure (>5 minutes) without a known rescue plan.

• Severe feeding trouble, choking, or suspected aspiration.

• Rapidly worsening scoliosis pain, hip pain/limp (possible SCFE, especially during GH therapy).

• Any sudden regression in skills. NCBI+1

Everyday diet: what to eat and what to limit

What to prioritize

• Balanced, texture-safe meals designed by a dietitian and SLP when swallowing issues exist.

• Protein at each meal (eggs, fish, poultry, legumes, dairy) to support growth and muscle strength.

• Calcium + vitamin D sources (dairy/yogurt/fortified alternatives, small fish with bones, leafy greens).

• Fiber and fluids (whole grains, fruits, vegetables, beans; plenty of water) to prevent constipation.

• Iron-rich foods (meat, legumes, fortified cereals) with vitamin C for absorption. NCBI

What to limit/avoid

• Hard, dry, or crumbly textures if there’s dysphagia (risk of choking) unless cleared after a swallow study.

• Sugary drinks/snacks that worsen dental issues and constipation.

• Reflux triggers (very spicy/fatty/acidic foods) if GERD is a problem.

• Restrictive fad diets unless prescribed by your clinical team; the ketogenic diet has only animal-model evidence in Kabuki and is not standard for neurodevelopment in humans with Kabuki. PubMedPNAS

Frequently asked questions

1. Is Kabuki syndrome curable?
   No. It’s lifelong. But many problems can be treated or improved, and quality of life can be good with the right supports. NCBI

2. How is Kabuki inherited?
   Most cases are new (de novo). KMT2D-related Kabuki follows autosomal dominant inheritance; KDM6A-related Kabuki is X-linked. A genetic counselor can explain family risks. NCBI

3. What specialists should we see?
   A multidisciplinary team (genetics, cardiology, ENT/audiology, GI, endocrinology, neurology, immunology, orthopedics/physiatry, ophthalmology, dental/craniofacial, developmental pediatrics, therapy services). Coordinated clinics exist in some centers. ScienceDirect

4. Will my child grow normally?
   Some have short stature; a subset has GH deficiency. Endocrinology can test for this, and rhGH may improve growth when indicated. PubMedKarger

5. What about learning and behavior?
   Development varies widely. Early therapies, school supports, and, when needed, ADHD or anxiety treatments help many children make strong progress. NCBI

6. Are infections more common?
   Some people have antibody deficiencies or autoimmune issues. Immunology checks immunoglobulins, vaccine responses, and may suggest IVIG or tailored vaccines/antibiotic plans. PubMedprimaryimmune.org

7. Is hearing loss expected?
   Ear fluid and infections are common. Hearing checks, ear tubes, and hearing aids (when needed) protect speech and learning. NCBI

8. Do we need heart tests?
   Yes, an echocardiogram is common at diagnosis because congenital heart differences are more frequent. Follow-up depends on findings. NCBI

9. Any promising new treatments?
   In mice, drugs that open chromatin (HDAC inhibitors, LSD1 inhibitors) and a ketogenic diet improved memory and neurogenesis. These are not yet approved for people with Kabuki, but research is active. PMC+1PubMed

10. Can adults be diagnosed?
    Yes. Some are recognized later, especially those with milder features. Adult care focuses on hearing, dental, cardiac, endocrine, orthopedic, and mental health needs. NCBI

11. What about pregnancy?
    Adults with Kabuki can become parents. Affected individuals have a 50% chance to pass on KMT2D-related Kabuki (autosomal dominant). Prenatal and preimplantation testing may be options if the familial variant is known. NCBI

12. Are there official guidelines?
    Formal, universally adopted guidelines are still being developed by global collaborators; expert centers already follow structured, evidence-informed care pathways. kabukisyndromefoundation.orgManchester Rare Conditions Centre

13. Is there a special diet for Kabuki?
    No standard “Kabuki diet.” Nutrition is individualized for growth, reflux, constipation, and safe swallowing. Ketogenic diet is not standard for Kabuki outside research. NCBIPubMed

14. Where can we find reliable information and research updates?
    GeneReviews, NORD, MedlinePlus, and the Kabuki Syndrome Foundation (KSF) provide high-quality resources and research news. NCBIRare DiseasesMedlinePluskabukisyndromefoundation.org

15. What is the long-term outlook?
    Outcomes vary, but many children and adults with Kabuki learn, communicate, and participate with tailored supports. Regular follow-up prevents and treats complications early. NCBI
