Cornelia de Lange Syndrome synonyms

Cornelia de Lange Syndrome (CdLS) is the preferred clinical term for this multisystem genetic condition, though it is historically known as Brachmann-de Lange syndrome or Amsterdam dwarfism. While medical literature may reference these older terms, the international medical community now uses Cornelia de Lange Syndrome to ensure consistency in diagnosis, research, and patient support.

Why does Cornelia de Lange Syndrome have multiple names?

The naming of Cornelia de Lange Syndrome reflects the history of its clinical identification. The condition was named after the Dutch pediatrician Cornelia de Lange, who described several cases in 1933. However, the syndrome had been described previously by German physician Winfried Brachmann in 1916. Consequently, for many years, the literature referred to it as Brachmann-de Lange syndrome. Another historical term, "Amsterdam dwarfism," was used in early literature due to the short stature often observed in individuals with Cornelia de Lange Syndrome, but this term is now considered outdated, imprecise, and stigmatizing. Modern nomenclature focuses on the clinical presentation and genetic etiology rather than descriptive or eponymous phrases.

What are the official medical classifications for this condition?

To avoid confusion in medical records and research, global health organizations utilize standardized codes for Cornelia de Lange Syndrome. These classifications help clinicians and researchers communicate effectively across borders:

• Orphanet: Recognized as ORPHA:207, which is the primary identifier for rare disease registries.


• OMIM (Online Mendelian Inheritance in Man): Cataloged under #122470 (for the classic form associated with the NIPBL gene).


• ICD-10/ICD-11: Classified under codes related to congenital malformation syndromes (Q87.1 in ICD-10).

What names might appear in older medical records?

If you are reviewing older medical charts or historical research papers, you may encounter several synonyms for Cornelia de Lange Syndrome. Understanding these terms can help patients navigate legacy documentation:

1. Brachmann-de Lange syndrome


2. Amsterdam dwarfism


3. Typus Amstelodamensis


4. De Lange syndrome


5. CDLS (the standard medical abbreviation)

Which term should I use when speaking to my doctor?

Medical professionals currently prefer Cornelia de Lange Syndrome or the abbreviation CdLS. Using the official name is the best way to ensure accurate communication with specialists, including clinical geneticists and pediatricians. At DiseaseMaps.org, where 133 community members have shared their experiences, we use the standardized term Cornelia de Lange Syndrome to ensure that families can easily connect with others sharing the same diagnosis, regardless of their country of origin or the specific historical terminology used by their local providers.

Next steps

• Consult with a clinical geneticist to verify the specific genetic variant associated with your diagnosis.


• Verify that your medical records use the official Cornelia de Lange Syndrome nomenclature to prevent confusion with other developmental conditions.


• Connect with the 133 members of the DiseaseMaps.org community to share resources and experiences.
