Usher Syndrome synonyms

Usher Syndrome is a genetic condition characterized by the association of sensorineural hearing loss and progressive vision loss due to retinitis pigmentosa. While it is primarily known as Usher Syndrome, it is occasionally referred to as Hallgren syndrome or Graefe-Usher syndrome in older medical literature, though these terms are now largely historical.

What are the historical and alternative names for Usher Syndrome?

In medical literature, Usher Syndrome is the standard term used globally. However, patients may encounter older or less common synonyms that reflect the historical evolution of the condition’s classification. Historically, the condition was sometimes called Graefe-Usher syndrome, named after Albrecht von Graefe, who first described the association between deafness and retinitis pigmentosa in 1858, and Charles Usher, who later identified the genetic nature of the condition in 1914. You may also see it occasionally referred to as Hallgren syndrome, particularly in older European psychiatric or neurological papers. Despite these historical labels, Usher Syndrome is the only term currently recognized by major international health organizations.

Why does Usher Syndrome have multiple names?

The existence of multiple names for Usher Syndrome is largely due to the way medical eponyms were assigned in the late 19th and early 20th centuries. Because the condition involves both otolaryngology and ophthalmology, researchers in different specialties often described the same patient cohort independently. As clinical genetics advanced, the medical community moved toward a unified nomenclature to prevent confusion. Today, researchers classify the condition based on clinical severity and genetic mutations (Type 1, Type 2, and Type 3) rather than using historical eponyms, which ensures that clinical records remain consistent and accurate across different medical systems.

What are the official classifications for Usher Syndrome?

To ensure clarity in medical records, clinicians and researchers rely on standardized classification systems. Using the correct name is vital for accessing clinical trials, genetic counseling services, and insurance coverage. The following identifiers are used by leading health authorities to track Usher Syndrome:

• Orphanet: Classified under ORPHA791.


• OMIM (Online Mendelian Inheritance in Man): Listed under various entries depending on the subtype (e.g., #276900 for Usher Syndrome Type 1A).


• ICD-10-CM: Identified under code H48.8 or related codes for hereditary retinal dystrophy and hearing loss.


• NIH GARD: Recognized as a rare genetic disorder under the name Usher Syndrome.

How is the condition referred to in international settings?

While Usher Syndrome is the universally accepted English term, you may see variations in other languages. In French, it is commonly referred to as Syndrome d'Usher, and in German, it is Usher-Syndrom. Regardless of the language, the clinical definition remains consistent. Within the DiseaseMaps community, which includes 214 members living with Usher Syndrome, the consensus is to use the standard terminology to facilitate better communication with specialists and to help families find relevant research and resources.

Next steps

• Consult a specialist: If you are unsure about your diagnosis, request a referral to a clinical geneticist or a neuro-ophthalmologist familiar with Usher Syndrome.


• Verify your records: Ensure your medical files use the term Usher Syndrome to avoid confusion with other forms of hearing or vision loss.


• Join the community: Connect with the 214 members on DiseaseMaps.org to share experiences and learn about the latest clinical trial opportunities.


• Genetic Testing: Speak with a genetic counselor to identify the specific genetic subtype, which is essential for understanding the progression of the condition.
