Toxic adenomas (TA) and toxic multinodular goiters (TMNG) are frequent causes of hyperthyroidism in Galicia, an endemic goiter area. In some European countries, 40–80% of toxic goiters are caused by TSH receptor (TSHr) and Gs alfa-subunit (Gsa) mutations that activate cAMP pathway.Aims: To study 1) the prevalence of TSHr and Gsa mutations in TMNG and TA from Galicia, 2) the clonality of sequenced samples, 3) the constitutive activity of the identifi...
