<prompt> All of the following are seen in follicular carcinoma of thryoid, except:PAX8-PPARG fusionRAS gene mutationsPoint mutations of TP53Loss-of-function mutations of PTEN gene  <response>: Genetics of follicular thyroid carcinomas: 30 to 50 of follicular carcinomas harbor RAS mutation. 20 to 50 of follicular carcinomas harbor PAX8-PPARG fusion. Up to 10 of follicular carcinomas exhibit gain-of-function mutations of PIK3CA the gene that encodes phosphoinositide 3-kinase or loss-of-function mutations of PTEN, a tumor suppressor gene and negative regulator of PI3K pathway. Point mutations of TP53, beta-catenin CTNNB1, and TE are seen in poorly differentiated and anaplastic carcinomas.
