On the other hand, in a study investigating the effects of autoimmunity on quality of life in 84 euthyroid HT patients, it was found that high Anti-TPO and Anti-TG antibody levels were significantly negatively correlated with quality of life scores and patients with high Anti-TPO and Anti-TG levels had significantly lower quality of life scores [37]. The gene discussed is TG; the disease is Autoimmunity.
