The Neonatal Acute Bilirubin Encephalopathy Registry

The NABER will administer a national voluntary registry of neonates with ABE in the USA over a 36-month period. Qualifying infants will receive 28-gene panel sequencing at no charge.

A REGISTRY WITH FREE NEXT GENERATION SEQUENCING

  • Acute bilirubin encephalopathy (ABE) occurs in ˜1 per 60,000 births in the U.S.
  • Previous publications report that ˜50% of neonates with a bilirubin ≥ 30 mg/dl have no clear explanation found for their jaundice.
  • The University of Utah with ARUP Laboratories developed a 28-gene Next Generation Sequencing (NGS) panel to discover underlying genetic contributors to ABE.
  • We have subsequently identified 7 cases of ABE among just over 428,000 live births (1 per 61,147 births) in Utah. Using the NGS panel, a genetic cause was found in all cases. None were “idiopathic” and all had hemolysis.
  • NABER is a 36-month national voluntary registry designed to conduct root-cause analysis of ABE cases in the USA.
  • Qualifying infants will receive 28-gene sequencing panel at no charge.
  • Participation in the NABER will require parental consent. Information and consent forms can be found on the kernicterus-registry.org website. Though the attending physician will provide forms to the family, questions regarding the study should be directed to study personal at the Unviersity of Utah by phone or email. Participation will require a 1 mL blood sample collected in an ETDA (purple-top) tube.

(1) total serum bilirubin ≥ 28mg/dl (or have undergone an exchange transfusion)
(2) signs of moderate to severe
encephalopathy; BIND ≥4 (see below)
