INTRODUCING
DIFFERENTIAL DIAGNOSIS
Fabry disease is a multisystemic disorder with a range of signs and symptoms, and should be considered in the differential diagnosis of many systemic diseases.
Fabry disease is a complex, multisystemic disorder with a broad range of signs and symptoms. Fabry disease should therefore be considered in the differential diagnosis of many systemic diseases.1 A diagnosis of Fabry disease can be delayed for many years (see misdiagnosis of Fabry disease), because the early disease indicators are often non-specific and there is limited awareness of the disease among clinicians. One of the major challenges in making a correct and timely diagnosis of Fabry disease is its lack of inclusion in a clinician’s differential diagnosis, particularly in young patients (see getting the diagnosis right).2
Genetic testing should be used to confirm a diagnosis of Fabry disease in females and to support a diagnosis in males.3-5 The alpha-galactosidase A (α-Gal A) enzyme assay can be used to diagnose Fabry disease in male patients.3-6 In addition, globotriaosylsphingosine (lyso-Gb3) is considered a useful diagnostic biomarker in some patients with Fabry disease,7-9 and clinical indicators can be used to assess the extent of organ involvement.10 A number of disease severity indexes are also available to assess the severity of Fabry disease.11-15
Once a patient has been diagnosed with Fabry disease, a thorough pedigree analysis is recommended to be performed to identify any family members at risk of the disease.16,17 Family screening for Fabry disease may also identify patients who are at risk of having children with the disease (see prenatal and newborn screening).18

Fabry Disease: Renal considerations for diagnosis
Renal manifestations occur early in the disease course; therefore, nephrologists are recommended to maintain an awareness of Fabry disease.
Events
WORLDSymposium™ 2022
The WORLDSymposium™ was held as a hybrid meeting this year (7–11 February 2022) and brought together key opinion leaders from the field of lysosomal disorders and rare diseases. Here you can access summaries from the meeting, including reports with a specific focus on Fabry disease.

Fabry Disease: Cardiac considerations for diagnosis
Due to the high prevalence of cardiac involvement in patients with Fabry disease, cardiologists are vital in the screening and diagnosis of the disease. Cardiologists are recommended to maintain an awareness of Fabry disease.

Fabry Disease: Neurological considerations for diagnosis
Neurologists can aid an early diagnosis of Fabry disease and document neurological involvement associated with the disease.
DIFFERENTIAL DIAGNOSIS
Getting the diagnosis right
Why can diagnosing Fabry disease be difficult for clinicians?
Diagnosis of Fabry disease can be difficult due to the diversity of clinical symptoms. Lack of knowledge of clinical findings and disease awareness can lead to misdiagnosis of Fabry disease by clinicians.
DIFFERENTIAL DIAGNOSIS
Signs and symptoms of Fabry disease
What are the signs and symptoms of Fabry disease?
The prevalence and age at onset of Fabry disease manifestations can vary between males and females but the severe multisystemic involvement of the disease may ultimately lead to major organ failure.
DIFFERENTIAL DIAGNOSIS
Diagnosis of Fabry disease
How can Fabry disease be diagnosed?
Genetic testing can confirm and support a diagnosis in females and males. The α-Gal A enzyme assay can diagnose Fabry disease in males.
