Kim et al. analyzed papillary thyroid tissue samples from 108 patients with thyroid cancer, 16 patients with nodular goitre and 81 healthy controls, and found that 65 of the 108 patients with papillary thyroid carcinoma were positive for KRT17, while KRT17 expression was negative in both nodular goitre and healthy controls, with statistically significant differences. This evidence concerns the gene KRT17 and thyroid cancer.
