Expert Opinion :
Since the patient had recurrent jaundice with itching and similar problem in another child, one would suspect conditions such as PFIC. However GGTP is elevated and liver biopsy is not suggestive of the same.
For Alagille syndrome, he does not have characteristic facies and echocardiography was normal.
He underwent an MRCP and it was suggestive of choledochal cyst.
