Genetic Heart Disease

Fabry Disease (Cardiac Involvement)

Genetic Disorder Causing Fat Build-Up in the Heart Leading to Thickening and Failure

Fabry Disease is a rare genetic disorder where a specific enzyme deficiency leads to accumulation of fatty substances (GL-3) in various organs, including the heart. Over time, this causes thickening of the heart muscle, arrhythmias, and progressive heart failure.

Understanding

What is Fabry Disease?

In Fabry disease:

  • Enzyme deficiency leads to buildup of fatty substances (GL-3)
  • Deposits occur in heart, kidneys, and blood vessels
  • Heart muscle becomes thick and stiff

This leads to:

  • Hypertrophic cardiomyopathy
  • Arrhythmias
  • Heart failure
Warning Signs

Early Signs & Symptoms

Burning Pain
Hands/Feet
Palpitations
Cardiac Symptom
Breathlessness

Multi-system symptoms → Important diagnostic clue
Risk Factors

Causes & Risk Factors

Cause

Genetic mutation (X-linked inheritance)

Risk Factors
  • Family history
  • Male gender (more severe)
  • Female carriers (milder but significant disease possible)
Progression

Disease Progression

Early Stage Subclinical involvement
Moderate Stage Cardiac thickening
Severe Stage Heart failure
End Stage Transplant needed

Early Stage

Subclinical organ involvement

Often undetected

Screening Needed

Moderate Stage

Cardiac thickening

Kidney involvement

ERT Initiation

Severe Stage

Heart failure

Arrhythmias

Heart Failure Management

End Stage

Multi-organ failure

Transplant required

Heart Transplant
Testing

Diagnosis & Tests

Enzyme assay (alpha-galactosidase activity)
Genetic testing
Echocardiography
Cardiac MRI
Kidney function tests

Genetic diseases require early screening

Assess your heart function risk

Management

Treatment Options (Before Transplant)

1. Enzyme Replacement Therapy
  • Replaces deficient enzyme
2. Chaperone Therapy
  • Stabilizes enzyme function
3. Heart Management
  • Medications for heart failure
  • Arrhythmia management

When is Heart Transplant Needed?

Advanced heart failure

Severe cardiac dysfunction

Poor response to therapy

Early Diagnosis Can Prevent Organ Damage

Family screening is critical

Important Consideration: Genetic Multi-Organ Disease

• Affects multiple systems • Often misdiagnosed • Requires lifelong management

Medical Therapy vs Transplant
Medical Therapy (ERT)

Stage: Early/Moderate • Goal: Prevent progression • Outcome: Slows disease

Heart Transplant

Stage: Advanced • Goal: Replace heart • Outcome: Life-saving
