Kabuki syndrome synonyms

Kabuki syndrome is officially recognized by its primary name, though it was historically referred to as Kabuki make-up syndrome due to the distinctive facial features that resemble the traditional Japanese Kabuki theatre actors. Today, medical professionals prefer the term Kabuki syndrome to avoid the potential stigmatization of the original descriptive label while maintaining consistency in clinical documentation and research.

Why are there different names for Kabuki syndrome?

The naming of Kabuki syndrome reflects its history of discovery. When the condition was first described in 1981 by Japanese researchers Norio Niikawa and Yoshikazu Kuroki, it was named Kabuki make-up syndrome because of the striking resemblance between the patients' lower eyelid eversion and the elaborate makeup worn by actors in Kabuki theater. As medical understanding of the underlying genetic causes evolved, the "make-up" portion of the name was dropped by most international medical organizations to emphasize the clinical reality of the disorder rather than the appearance of the affected individuals. In some older medical literature or international reports, you may still encounter the original name, but Kabuki syndrome is the universally accepted terminology in modern clinical practice.

How is Kabuki syndrome classified in medical systems?

Consistency in nomenclature is essential for medical records and insurance billing. Across major global classification systems, the condition is categorized as follows:

• OMIM (Online Mendelian Inheritance in Man): Listed under ID #147920 (Kabuki syndrome 1) and #300867 (Kabuki syndrome 2).


• Orphanet: Classified under the primary name Kabuki syndrome (ORPHA:471).


• ICD-10/11: Often coded under broader categories for congenital malformation syndromes, as specific codes vary by region.

What are the common synonyms and abbreviations?

While Kabuki syndrome is the preferred name, patients and families may encounter various terms depending on the era of the medical documentation or the geographic region of the specialist. Common variations include:

• Kabuki make-up syndrome (Historical/Original name)


• Niikawa-Kuroki syndrome (Named after the physicians who first identified the condition)


• KS (The standard medical abbreviation)

Is there a difference between the types of Kabuki syndrome?

The nomenclature has become more precise as we have identified specific genetic drivers. Kabuki syndrome is currently divided into two types based on the gene involved: Type 1, caused by mutations in the KMT2D gene, and Type 2, caused by mutations in the KDM6A gene. Despite these genetic distinctions, the clinical phenotype is generally referred to by the single, umbrella term Kabuki syndrome.
