Living with Neonatal ichthyosis-sclerosing cholangitis syndrome

A very rare inherited condition with dry, scaly skin, sparse hair, and liver bile duct problems, seen from the newborn period.

Understanding Neonatal ichthyosis-sclerosing cholangitis syndrome

Neonatal ichthyosis-sclerosing cholangitis syndrome (NISCH) is a very rare inherited condition affecting the skin, hair, and liver.

It involves thin scalp hair, hair loss with scarring, dry scaly skin (ichthyosis), and sclerosing cholangitis, which is inflammation and narrowing of the bile ducts in the liver. Signs start in the newborn period.

Signs & symptoms

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

  • Dry, scaly skin (ichthyosis)
  • Sparse scalp hair and scarring hair loss
  • Sparse eyebrows and eyelashes
  • Slowed bile flow from the liver (cholestasis)
  • Yellowing of the skin (jaundice)
  • Enlarged liver and spleen

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, genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in CLDN1 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

    Foundation for Ichthyosis and Related Skin Types may keep lists of experts for this condition.
