Living with Progressive familial intrahepatic cholestasis type 3

A rare genetic liver condition that starts in late infancy or childhood, with itching and jaundice.

Understanding Progressive familial intrahepatic cholestasis type 3

Progressive familial intrahepatic cholestasis type 3 (PFIC3) is a rare genetic condition that affects the liver.

Symptoms usually begin in late infancy or early childhood, though GARD says onset can be any time in life. They may include severe itching, jaundice, slow growth, and an enlarged liver and spleen. The liver condition may progress to liver failure during childhood or adulthood.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Itching (pruritus)
  • Yellow skin and eyes (jaundice)
  • Enlarged liver and spleen
  • Scarring of the liver (cirrhosis)
  • Fluid buildup in the belly (ascites)
  • Diarrhea and trouble absorbing food (malabsorption)

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 ABCB4 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
