Association of CYP2D6*4 gene polymorphism with early papillary thyroid carcinoma

Abstract

Objectives: CYP2D6 is highly polymorphic and a common variant CYP2D6*4 results in the generation of poor metabolizer enzyme. The CYP2D6*4 variant has been associated with altered susceptibility to several cancers. The aim of the present case-control study aims to investigate the association between CYP2D6*4 polymorphism and the risk of papillary thyroid carcinoma (PTC).
