UTP4 is a gene that encodes the protein Cirhin, the gene is also known as CIRH1A and NAIC.[5][6][7] This protein contains a WD40 repeat and is localized to the nucleolus where it colocates with UTP15 and WDR43.[8] Biallelic mutations to UTP4 have been associated with North American Indian childhood cirrhosis, a form of inherited cirrhosis of the liver occurring in American Indian children from the Abitibi region of northern Quebec.[9]
