Ullrich Congenital Muscular Dystrophy synonyms

Ullrich congenital muscular dystrophy (UCMD) is most commonly referred to by its full clinical name, though it is sometimes classified under the broader umbrella of Collagen VI-related dystrophies. While historical literature may use various terms, Ullrich congenital muscular dystrophy is the standard nomenclature used by clinicians and researchers today to ensure clear communication regarding this specific genetic condition.

What are the common synonyms and historical names for Ullrich congenital muscular dystrophy?

In medical literature, Ullrich congenital muscular dystrophy is occasionally identified by its abbreviation, UCMD. Historically, this condition was sometimes described simply as a form of "congenital muscular dystrophy with joint hyperlaxity," though this term is imprecise and no longer favored. Because Ullrich congenital muscular dystrophy is caused by mutations in the COL6A1, COL6A2, or COL6A3 genes, it is frequently grouped into the clinical category of "Collagen VI-related myopathies" or "Collagen VI-related dystrophies." Using the specific name Ullrich congenital muscular dystrophy helps distinguish this phenotype from milder forms of collagen VI-related conditions, such as Bethlem myopathy.

How is the condition classified in medical databases?

Standardized medical databases utilize specific identifiers to categorize Ullrich congenital muscular dystrophy, aiding in global research and clinical record-keeping:

• OMIM (Online Mendelian Inheritance in Man): #254090


• Orphanet: ORPHA265


• ICD-10-CM: G71.09 (Other specified muscular dystrophies)

Why does Ullrich congenital muscular dystrophy have multiple names?

The existence of multiple names for Ullrich congenital muscular dystrophy stems from the evolution of genetic testing. Before the genetic basis of the disease was fully understood, patients were often classified based solely on physical symptoms. As clinicians identified the underlying collagen deficiency, the field shifted toward using "Collagen VI-related dystrophy" as a primary classification. However, Ullrich congenital muscular dystrophy remains the preferred term for professionals because it specifically describes the severe, early-onset phenotype characterized by distal joint hyperlaxity and proximal joint contractures.
