Classic Fabry disease symptoms like angiokeratoma and acroparaesthesia are often absent in patients. This study suggests updating terminology for better diagnosis of this treatable condition.
Area of Science:
- Genetics
- Rare Diseases
- Dermatology
- Neurology
- Cardiology
Background:
- Classic Fabry disease presents with skin lesions (angiokeratoma), nervous system issues (acroparaesthesia), and heart problems (restrictive cardiomyopathy).
- Established diagnostic criteria may not accurately reflect the presentation in all patients.
- A cohort of 100 genetically confirmed Fabry disease patients was studied.
Purpose of the Study:
- To evaluate the accuracy of classic Fabry disease signs and symptoms in genetically confirmed patients.
- To propose updated terminology for improved diagnosis and physician understanding.
Main Methods:
- Genetic testing confirmed Fabry disease in 100 patients.
- Standardized examinations were performed on all patients.
- Clinical findings were compared against textbook descriptions.
Main Results:
- Skin lesions (angiokeratoma) were often without hyperkeratosis and keratomas were rare.
- Peripheral neuropathic pain was observed, but the term 'acroparaesthesia' was deemed inaccurate.
- Cardiac findings primarily included diastolic dysfunction, with only one patient showing a restrictive pattern.
Conclusions:
- Traditional terms for Fabry disease symptoms (angiokeratoma, acroparaesthesia, restrictive cardiomyopathy) may be outdated and misleading.
- Proposed new terms: 'angioma' for angiokeratoma, 'neuropathic pain' for acroparaesthesia, and 'cardiac hypertrophic storage disease' for restrictive cardiomyopathy.
- Updating terminology can aid physicians in diagnosing this treatable genetic disorder.
