Abstract

Progressive familial intrahepatic cholestasis type 4 (PFIC4) is a relatively newly described autosomal recessive disorder caused by biallelic mutations in the gene encoding tight junction protein 2 (TJP2) which is located in chromosome 9q21. PFIC4 is characterised by cholestasis with or without other extrahepatic manifestations. Bleeding tendency due to vitamin k deficiency is a well-known complication of cholestasis. We present a neonate who presented to the Emergency Department at a tertiary care hospital in 2021 with cholestasis and multiple intracranial bleeds. He was found to have severe coagulopathy and his genetic work up revealed a homozygous variant mutation in TJP2 gene causing PFIC4. He had persistent cholestasis that necessitated an internal biliary diversion with some clinical improvement.
