Turner Syndrome synonyms

Turner Syndrome is primarily known by its eponymous name, though it is historically and clinically referred to as Ullrich-Turner syndrome or Bonnevie-Ullrich syndrome. In medical classification systems, it is most commonly categorized as monosomy X, reflecting the partial or complete absence of a second X chromosome, which serves as the definitive clinical identifier for Turner Syndrome patients.

What are the historical and alternative names for Turner Syndrome?

Over the decades, Turner Syndrome has been known by several names, many of which reflect the researchers who first described its clinical features. The term "Ullrich-Turner syndrome" is frequently encountered in European medical literature, honoring both Otto Ullrich and Henry Turner for their independent contributions to identifying the condition's characteristics in the 1930s. Other historical terms include Bonnevie-Ullrich syndrome, which was used when describing the specific phenotype involving lymphedema and webbed neck. While these terms appear in older textbooks, they are increasingly replaced by the standard designation of Turner Syndrome in modern clinical practice to ensure universal consistency.

How is Turner Syndrome classified in medical systems?

Standardized medical databases use specific nomenclature to ensure accurate coding and international communication. The official classification systems include:

• Orphanet: Recognized as ORPHA:881, listed under the name Turner Syndrome.


• OMIM (Online Mendelian Inheritance in Man): Cataloged under #300087.


• ICD-10/11: Classified under codes Q96.0 through Q96.9, which differentiate between full monosomy (45,X) and mosaic variants of Turner Syndrome.

Why does this condition have multiple names?

The variety of names associated with Turner Syndrome stems from the evolution of medical diagnostics. Before the 1959 discovery that the condition was caused by a chromosomal abnormality, clinicians named the syndrome after the physicians who identified its physical traits. As genetic sequencing advanced, the term "monosomy X" became a preferred scientific description because it accurately identifies the underlying biological cause: the loss of all or part of an X chromosome. Today, medical professionals prefer Turner Syndrome for clinical diagnosis, while "monosomy X" or "45,X" is used in genetic reports to describe the specific karyotype.

What should patients know about current terminology?

It is common for patients to encounter different terms in their medical records, especially if they are seeing specialists in different countries or referring to older health files. Understanding that these synonyms—such as Gonadal Dysgenesis or Ullrich-Turner syndrome—all refer to the same condition can help reduce confusion. Within the DiseaseMaps.org community, where 414 people with Turner Syndrome have shared their experiences, members often use the primary name to facilitate better networking and resource sharing. Using the standard name helps ensure that your search for support groups, clinical trials, and research literature remains focused and effective.

Next steps

• Consult with a clinical geneticist to clarify your specific karyotype and how it relates to your diagnosis.


• Review your medical records; if you see terms like "Gonadal Dysgenesis," confirm with your endocrinologist that they are referring to your Turner Syndrome diagnosis.


• Join the DiseaseMaps.org community to connect with others who have navigated the terminology and care pathways of this condition.


• Stay informed on the latest research through the Turner Syndrome Foundation or NIH GARD portals.
