Further studies of genetic susceptibility to Graves' disease in a Russian population.

Background: Graves' disease (GD) is a polygenic autoimmune thyroid syndrome. Some of the genes implicated in its pathogenesis may encode thyroid-stimulating hormone receptor (TSHR) and estrogen receptors 1 (ESR1) and 2 (ESR2). We examined dinucleotide repeat polymorphisms in the ESR1 and ESR2 genes and D727E amino acid substitution in the TSHR gene for possible association with GD in a Russian population.
