Transient familial hyperbilirubinemia is a metabolic disorder that is passed down through families. Babies with this disorder are born with severe jaundice.
Transient familial hyperbilirubinemia is an inherited disorder. It occurs when the body does not properly break down (metabolize) a certain form of bilirubin. Bilirubin levels rapidly build up in the body. The high levels are poisonous to the brain and can cause death.
The newborn may have:
- Yellow skin (jaundice)
- Yellow eyes (icterus)
If untreated, seizures and neurologic problems (kernicterus) may develop.
Exams and Tests
Blood tests for bilirubin levels can identify the severity of the jaundice.
Babies who are treated can have a good outcome. If the condition is not treated, severe complications develop. This disorder tends to improve with time.
Death or severe brain and nervous system (neurological) problems can occur if the condition is not treated.
When to Contact a Medical Professional
This problem is most often found immediately after delivery. However, contact your health care provider if you notice your baby's skin turning yellow. There are other causes for jaundice in the newborn that are easily treated.
Genetic counseling can help families understand the condition, its risks of recurring, and how to care for the person.
Phototherapy can help prevent serious complications of this disorder.
