Inosine triphosphatase genetic variants are protective against anemia during antiviral therapy for HCV2/3 but do not decrease dose reductions of RBV or increase SVR

Shianna, Leonardo Mottola, Daniela Petruzzellis, Mario Romano, Fernando Sogari, Domenico Facciorusso, David B. Goldstein, John G. McHutchison, Alessandra Mangia – 12 November 2010 – Two functional variants in the inosine triphosphatase (ITPA) gene causing inosine triphosphatase (ITPase) deficiency protect against ribavirin (RBV)‐induced hemolytic anemia and the need for RBV dose reduction in patients with genotype 1 hepatitis C virus (HCV).
