Kabuki Syndrome
New Kabuki syndrome research, summarized each month in plain language.
2026 so far: January 2026 to September 2026 reports highlighted neonatal or persistent low blood sugar (including medication-treated hyperinsulinism) and clearer diagnostic tools, alongside single-patient reports of complex surgeries and rare complications. Read the 2026 review
We also cover clinical trials.
Yearly update
2026 so far
- Low blood sugar pattern. Shifted from occasional concern to a genotype-linked pattern.
- Complex care examples. Case reports expanded the range of high-complexity situations.
- Heart surgery outcomes. One cohort added longer-term outcome detail by anatomy.
- Better diagnosis tools. New lab classifier plus case reports highlighted limits of earlier tests.
- Tracking cognition and behavior. Outcome measures became more defined for KS1 and KS2.
New
September 2026
- Heart surgery outcomes. In-hospital risk was highest with more complex heart anatomy.
- Peer relationships. Caregivers often reported difficulties with peer relationships.
- KS1 and KS2 patterns. KS2 reports showed broader social communication difficulties than KS1.
- Lab research tools. New mouse and stem-cell models were developed for KS1 research.
August 2026
- Stable thinking measures. Several visuospatial and attention tasks gave similar repeat results.
- Visuospatial weakness. Visuospatial skills were the most consistent difficulty in KS1.
- Floor effect limits. One visuospatial test hit the lowest scores, limiting change tracking.
- Nuclear stress signaling. KMT2D loss was linked to nuclear stress signaling in lab studies.
July 2026
- Prenatal genetics. Ultrasound was nonspecific; exome testing found KMT2D changes.
- Two genetic findings. One fetus had Kabuki syndrome plus another genetic condition.
- Hirschsprung disease. One newborn was later diagnosed and needed bowel surgery.
- Teeth and bite. One report described major tooth and bite differences.
June 2026
- Newborn diagnosis. Genetic testing diagnosed Kabuki syndrome type 1 in a newborn.
- New KMT2D variant. A new truncating KMT2D variant adds to known gene changes.
- Heart and chest findings. The newborn had severe heart obstruction and chest-related problems.
May 2026
- DNA methylation blood test. A blood-based DNA methylation “fingerprint” identified Kabuki syndrome type 1 (KMT2D-related) with very high accuracy.
- Some KS2 cases also flagged. The same methylation pattern also classified some Kabuki syndrome type 2 (KDM6A-related) cases.
- Additional KMT2D variants reported. Small reports described additional KMT2D variants, including some that had not been reported before.
April 2026
- HLH case reported. A published case report described a rare immune over-reaction called hemophagocytic lymphohistiocytosis (HLH) in a person with Kabuki syndrome.
- Signs seen in this case. In this patient, the reported sign pattern included persistent fever, low blood counts, and enlarged organs.
- Prompt recognition emphasized. The authors emphasized early recognition and diagnosis of HLH in this situation.
March 2026
- Exome testing after normal microarray. In one report, exome sequencing identified Kabuki syndrome even though chromosome microarray testing was normal.
- Uncommon added findings. Some case reports described Kabuki syndrome occurring alongside other uncommon findings in individual patients.
- Specific eye changes and vision risk. New case reports linked vision-threatening problems to specific eye findings in Kabuki syndrome.
- Hip reconstruction follow-up. One child had improved hip imaging about a year after a single-stage reconstruction for hip dysplasia.
February 2026
- Neonatal low blood sugar. Some children with Kabuki syndrome were reported to have neonatal low blood sugar due to congenital hyperinsulinism, and a smaller subset had ongoing episodes treated with medicines.
- Kabuki found during other workups. KMT2D variants were sometimes identified during genetic testing that started for vertebral malformations or differences of sex development, which can lead to a Kabuki syndrome diagnosis during evaluation for other concerns.
January 2026
- Diabetes plus small kidneys. One case report described sudden-onset diabetes with small kidneys and an additional HNF1B gene change, suggesting that more than one genetic condition can sometimes be present.
- Spine fusion with revisions. One case report described severe upper-back curvature treated with spinal fusion and multiple revision surgeries, with an infection during recovery and later follow-up noting improved function.
