Ehlers Danlos synonyms

Ehlers-Danlos syndromes (EDS) comprise a group of 13 distinct hereditary connective tissue disorders, formerly known collectively as Ehlers-Danlos syndrome, which are now classified based on specific genetic mutations and clinical features.

Historical and Alternative Terminology

Historically, the condition was frequently referred to as cutis hyperelastica, a descriptive term highlighting the characteristic skin hyperextensibility. In older medical literature, you may encounter names such as "India-rubber skin" or "fibrodysplasia elastica generalisata." While these terms are largely obsolete, they appear in legacy patient records and older research papers. The term "Ehlers-Danlos" itself honors Edvard Ehlers and Henri-Alexandre Danlos, who described the condition at the turn of the 20th century.

Current Classification and Nomenclature

The medical community transitioned from a singular diagnostic label to the plural "Ehlers-Danlos syndromes" following the 2017 International Classification system. This change reflects the understanding that EDS is not one condition, but a spectrum of related disorders. Today, clinicians prefer specific designations, such as:

• hEDS (Hypermobile Ehlers-Danlos syndrome): The most common form, currently without a known single causative gene.


• cEDS (Classical Ehlers-Danlos syndrome): Characterized by specific skin and joint criteria.


• vEDS (Vascular Ehlers-Danlos syndrome): The most severe form, often involving the COL3A1 gene.

Why Multiple Names Exist

The evolution of Ehlers-Danlos syndrome nomenclature is driven by advances in molecular genetics. As researchers identified the distinct genetic triggers—such as mutations in collagen genes—the classification system was revised to improve diagnostic accuracy and management strategies. Orphanet and the NIH GARD categorize these under the broad umbrella of Ehlers-Danlos syndromes to ensure patients can navigate complex medical systems, though clinicians now emphasize the specific subtype for targeted care.
