We identified two variations in genes in which germline variations cause susceptibility to FNMTC (Supplementary Table S1) and in 13 somatic genes with genetic alterations in malignant thyroid nodules (NRAS, HRAS, KRAS, THADA, PIK3CA, BRAF, TERT, PAX/PPARG, PTEN, DICER, E1F1AX, TSHR, and TP53) [57]. The gene discussed is KRAS; the disease is familial papillary or follicular thyroid carcinoma.
