摘要: Objective The genes causing Familial Non-Medullary Thyroid Carcinoma (FNMTC) identified to date are only involved in a small fraction of the families. Recently, somatic mutations TERT promoter region and EIF1AX gene were reported thyroid tumours undefined familial status. The aim present study was investigate role tumours. Design The sequenced leukocyte DNA probands from 75 FNMTC In 54 cases, we assessed promoter, RAS BRAF hotspot mutations, whole gene. Results No potentially pathogenic germline variants families’ probands. carcinomas, five cases (9%) with mutations. found 41% tumours. All positive samples also for p.Val600Glu this co-occurrence be statistically significant (P=0.008). detected four wild-type (7%). Evaluation tumour mutation data together patients’ clinicopathological features revealed correlation between plus advanced stage (T4) (P=0.020). No EIF1AX. Conclusions The results suggest that not frequently aetiology. However, show first time alterations associated progression. Our more often concomitance stages FNMTC.
