[/INST] Hello.Welcome to HCM forum.it is an inherited cause of unconjugated hyperbilirubinemia presenting in the first days of life with jaundice and with or without CNS symptoms.The ultimate treatment is liver transplant before irreversible kernicterus develops.Till then carry on with phenobarbitone.Thanks and good luck. </s>
