Associations between single nucleotide polymorphisms in thyroid hormone transporter genes (MCT8, MCT10 and OATP1C1) and circulating thyroid hormones

Two SNPs in MCT8 were related to circulating thyroid hormone levels in men but not in women: the rs5937843 polymorphism (G/T) was inversely associated with FT4 levels and the rs6647476 (T/C) polymorphism related negatively to circulating FT3.
