Three Mutations (p.Q36H, p.G418fsX482, and g.IVS19-2A>C) in the Dual Oxidase 2 Gene Responsible for Congenital Goiter and Iodide Organification Defect

Abstract

Two previously unknown compound heterozygous mutations in the DUOX2 gene, p.Q36H/p.S965fsX994 and p.G418fsX482/g.IVS19-2A>C, are responsible for iodide organification defects in 2 unrelated families. Identification of the molecular basis of this disorder might be helpful for understanding the pathophysiology of this congenital hypothyroidism.
