Notice that the “Thyroid carcinoma” is linked with another group of several cancer-related diseases (highlighted with a light blue circle), such as: “Oligodendroglioma,” “Multiple malignancy syndrome,” “Li-Fraumeni syndrome,” “Sezary syndrome,” “Lymphoma, “Adrenocortical carcinoma,” “Dermatobrosarcoma protuberans,” “T-cell lymphoblastic leukemia” and “Li-Fraumeni syndrome.” Future investigations could analyze whether the “Thyroid carcinoma,” as a cancer-related to the thyroid, could be explored as a bridge between cancer-related diseases and other thyroid diseases through the TSHR gene. The gene discussed is TSHR; the disease is thyroiditis.
