What is a Fabry test?
The primary blood test for the diagnosis of Fabry disease assesses the activity of the alpha-galactosidase A enzyme. Another blood test, which detects the presence of a fatty substance called lyso-Gb3, also can be performed and may indicate the severity of the disease.
How do you test for Fabry disease?
A GLA gene test is performed to diagnose Fabry disease. Males with Fabry disease can usually be diagnosed via an enzyme assay test. Males with classic Fabry disease essentially have no alpha-galactosidase A enzyme (less than 1% of normal).
How does Fabry disease affect the brain?
As a result, many neurological deficits may occur in a patient with Fabry disease. These include hemiparesis, vertigo/dizziness, diplopia, dysarthria, nystagmus, nausea/vomiting, headaches, hemiataxia and dysmetria, cerebellar gait ataxia and, very rarely, cerebral haemorrhage [4].
When do Fabry symptoms start?
Classic type: Symptoms of classic Fabry disease appear during childhood or the teenage years. One hallmark disease symptom — a painful burning sensation in the hands and feet — may be noticeable as early as age two.
Why is Fabry disease misdiagnosed?
FD can be misdiagnosed as multiple sclerosis (MS) because patients with either disease can present with pain and white matter lesions on magnetic resonance imaging (MRI).
What kind of medical assistance is needed for Fabry disease?
The only treatment approved specifically for Fabry disease in the United States is agalsidase-beta (Fabrazyme). This medication is an enzyme replacement therapy (ERT) and is a manufactured version of the enzyme that is lacking in Fabry disease. Fabrazyme is given by infusion through an IV every 2 weeks.
What does Fabry disease feel like?
Many Fabry disease patients experience gastrointestinal symptoms such as diarrhea, abdominal cramping, frequent bowel movements, flatulence, early satiety or having a feeling of fullness earlier than normal, reduced appetite, nausea, and/or vomiting.
What is the long term outlook for a child with Fabry disease?
The life expectancy of males with Fabry disease is about 58 years, and the life expectancy of females with Fabry disease is just over 75 years. The most common cause of death in both genders is cardiovascular disease.
Is Fabry an autoimmune disease?
Discussion: Fabry disease is multi-systemic and shares common symptoms with autoimmune rheumatic diseases, for example fatigue (62%) and neuropathic pain (77%). The co-existence of Fabry disease and lupus nephritis histology on renal biopsy has previously been reported.
