Core Tip
Core tip: Single nucleotide polymorphisms in the interferon L3 (IFNL3) gene have been associated with both spontaneous and treatment-induced clearance of hepatitis C virus in children. Data from adult studies suggest a role of IFNL3 testing in the decision-making process of whether to treat a patient, the use of two or three drugs and whether the standard duration of treatment or a shorter duration should be proposed. These options are attractive if applicable to children. While waiting for the approval of new interferon-free regimens, paediatric collaborative studies to evaluate the possible role of genetic polymorphisms of IFNL3 as pre-treatment and on-treatment predictors of response, alone or together with other predictors, are highly needed.
