North American Indian childhood cirrhosis

North American Indian childhood cirrhosis (NAIC) is a disease in humans that can affect Ojibway-Cree children in northwestern Quebec, Canada.[1] The disease is due to an autosomal recessive abnormality of the CIRH1A gene, which codes for cirhin.[2]

NAIC is a ribosomopathy.[3][4] An R565W mutation of CIRH1A[2][5] leads to partial impairment of cirhin interaction with NOL11.[5]

Initial transient neonatal jaundice advances over time to biliary cirrhosis with severe liver fibrosis.[1] Eventually, liver failure occurs, and requires liver transplantation.[1]
