E75.21
Fabry (-Anderson) disease
Clinical Classification Guidelines
Medical Intelligence & Overview
Fabry disease, also known as Anderson-Fabry disease, is a rare genetic disorder that affects the body's ability to process a specific type of fat. This buildup of fat can cause damage to various organs over time, including the kidneys, heart, and skin. It is inherited in an X-linked pattern, meaning males are more frequently and severely affected, but females can also experience symptoms.
Causes & Symptoms
Clinical Causes: Genetic mutation in the GLA gene Inheritance in an X-linked pattern from a carrier mother Deficiency of the enzyme alpha-galactosidase A Accumulation of globotriaosylceramide (Gb3) fat in cells
Key Symptoms: Experience of burning pain or numbness in hands and feet Skin rashes or clusters of small, dark red spots called angiokeratomas Corneal clouding that may affect vision Gradual loss of kidney function leading to kidney failure Cardiac issues such as irregular heartbeats, chest pain, or heart failure Gastrointestinal discomfort including diarrhea and abdominal pain Fatigue and weakness Frequent episodes of fever without obvious cause Reduced sweating or excessive sweating Hearing loss or ringing in the ears (tinnitus)
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves blood tests to measure enzyme activity levels. A genetic test can confirm the mutation in the GLA gene. Sometimes, a tissue biopsy may be performed to analyze the accumulation of specific fats within cells. Early diagnosis can help manage symptoms and prevent severe complications.
Treatment Protocols: While there is no cure for Fabry disease, treatments can help manage symptoms and prevent organ damage. Enzyme replacement therapy (ERT) is a common approach, designed to supplement the missing or deficient enzyme. Other supportive treatments may include medications for pain, skin lesions, and organ-specific complications. Regular monitoring of organ function is essential for effective management.
