Living with GRACILE syndrome

A severe inherited condition that begins before birth, affecting growth, the liver, the kidneys, and how the body handles iron and lactic acid.

Understanding GRACILE syndrome

GRACILE syndrome is a severe inherited disorder that begins before birth.

The name stands for growth retardation, aminoaciduria (extra amino acids in the urine), cholestasis (reduced bile flow), iron overload, and lactic acidosis. Babies grow slowly before birth, are smaller than average, and don't gain weight as expected. Excess iron in the liver likely begins before birth. Lactic acid builds up within the first day of life. Cholestasis leads to irreversible liver scarring (cirrhosis) in the first months.

Signs & symptoms

Symptoms vary. GARD lists these among the most common:

  • Slow growth before birth
  • Liver scarring (cirrhosis)
  • Reduced bile flow (cholestasis)
  • Hearing impairment

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include digestive system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in BCS1L are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    United Mitochondrial Disease Foundation and MitoAction may keep lists of experts for this condition.

Everyday life

Living with a rare condition is easier with support.

  • Connect with United Mitochondrial Disease Foundation and other patient organizations
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Can genetic testing confirm a change in the BCS1L gene?
Which specialists should be involved in my baby's care, such as liver and metabolic teams?
How can the liver and kidneys be supported?
