Tyrosinemia

A Rare Genetic Disorder Causing Toxic Build-Up in the Liver

Tyrosinemia is a rare inherited metabolic disorder where the body cannot properly break down the amino acid tyrosine, leading to toxic substance accumulation that damages the liver and kidneys. It can lead to liver failure if not treated early.
Quick Facts

Liver, kidneys

⚠️ Cause

Genetic enzyme deficiency

📈 Progression

Rapid in infants; variable in older

What is Tyrosinemia?

Tyrosinemia is a metabolic disorder where the body cannot properly break down tyrosine due to enzyme deficiency.

This leads to:

  • Toxic metabolite accumulation
  • Liver cell damage
  • Kidney dysfunction

Types include:

  • Type I (most severe) – affects liver and kidneys
  • Type II & III – milder but still significant
How Tyrosinemia Affects the Body
Genetic Mutation
FAH gene mutation
Toxic Buildup
Succinylacetone accumulation
Liver Damage
Cirrhosis, failure
Kidney Damage
Renal dysfunction
Important: Pediatric Focus - Early childhood diagnosis is critical. Family screening is recommended.
Early Signs & Symptoms
In Infants
  • Jaundice
  • Poor feeding
  • Vomiting
  • Growth failure
In Older Children
  • Liver enlargement
  • Weakness
  • Bone pain
Early onset symptoms → Urgent evaluation required
Causes & Risk Factors

Primary Cause: Genetic mutation affecting tyrosine metabolism (FAH gene)

Risk Factors:

  • Family history
  • Consanguineous marriages
Disease Progression
Early Stage (Toxic buildup)
Moderate Stage (Liver dysfunction)
Advanced Stage (Liver failure)
End Stage Liver Disease

Check Your Liver Risk

Understand your metabolic liver risk

Diagnosis & Tests
✔️ Blood amino acid levels
✔️ Urine metabolic tests (succinylacetone)
✔️ Liver function tests
✔️ Genetic testing
✔️ Imaging (ultrasound)
Treatment Options (Before Transplant)
1. Medical Therapy

NTBC (nitisinone) therapy

2. Dietary Management

Low-tyrosine diet, Special medical nutrition

3. Monitoring

Regular liver function, Growth tracking

When is Liver Transplant Needed?
  • Liver failure develops
  • Medical therapy is ineffective
  • Risk of liver cancer increases
Early Treatment Can Prevent Severe Damage
Timely diagnosis improves survival significantly

Frequently Asked Questions

Manageable with early treatment. NTBC therapy can prevent severe complications.

Yes, it is an inherited metabolic disorder.

No, only in severe or late-stage cases where medical therapy fails.

Final Guidance

Pediatric liver diseases require early diagnosis and specialized care. Timely intervention can prevent life-threatening complications.

Stay informed. Act early.
