Living with Neonatal intrahepatic cholestasis due to citrin deficiency

A liver condition in babies younger than one year, in which bile flow is blocked for a time; it is generally not severe.

Understanding Neonatal intrahepatic cholestasis due to citrin deficiency

Neonatal intrahepatic cholestasis due to citrin deficiency (NICCD) is a liver condition, also known as neonatal-onset type II citrullinemia.

NICCD blocks the flow of bile (a digestive fluid made by the liver) and keeps the body from processing certain nutrients properly. This causes temporary bile flow problems in the liver and variable liver problems in children younger than one year. It is generally not severe.

Signs & symptoms

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

  • Yellowing of the skin (jaundice)
  • Enlarged liver
  • Blocked or slowed bile flow (cholestasis)
  • Poor weight gain
  • Diarrhea
  • Slow blood clotting

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 genetic specialists.

  3. Consider genetic testing

    Changes in SLC25A13 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

InheritanceAutosomal Recessive
GenesSLC25A13

It is caused by changes in the SLC25A13 gene. A child inherits a changed copy of the gene from each parent (autosomal recessive).
