Other studies have explored the relationship between hyperthyroidism and other related diseases, such as the analysis of KCNJ18 gene mutations in hyperthyroidism associated with hypokalemic periodic paralysis (23), the study of BRAF gene mutations in hyperthyroidism associated with thyroid papillary carcinoma (24), and the study of UGT1A1 gene mutations in hyperthyroidism associated with liver failure (25). The gene discussed is UGT1A1; the disease is hyperthyroidism.
