Autoimmune thyroiditis, or Hashimoto's thyroiditis, can be identified by the presence of Anti-Thyroglobulin [ATG] and/or Anti-Thyroid Peroxidase [ATPO] antibodies in the serum with or without thyroid hormone abnormalities (in a euthyroid state) or clinical symptoms [7]. This evidence concerns the gene ATP5PO and autoimmune thyroid disease.
