Thyroid hemiagenesis (TH) is a rare inborn anomaly presenting as failure of the development of one thyroid lobe. Recent research on the molecular background underlying thyroid dysgenesis have mainly focused on patients with congenital hypothyroidism; in contrast, subjects presenting TH were only sporadically involved. Changes in transcription factor genes, including TTF1, TTF2 and PAX8, which play an important role in thyroid embryogenesis, have been postu...
