Molecular genetics of diffuse sclerosing papillary thyroid cancer.

In DSPTC, fusion genes are common, BRAFV600E is rare, and other usual point mutations are absent. Pathogenic and likely pathogenic variants in POLE, NF1, CDKN2A, BRCA2, TP53, SETD2, ATM, FLT3 and ROS1 occur in about two-thirds of DTPTC.
