WebAug 15, 2024 · GIST patients age 30 and under at the time of diagnosis should be evaluated by a qualified SDH GIST Specialist and have SDH IHC/SDH mutation testing (NGS) performed. When seeing a GIST specialist for the first time, it is helpful to take a copy of your pathology report with you. Pathology and mutation terminology can be confusing. WebThe most common secondary gene mutations in people with GIST are in KIT and PDGFRα, as we’ve mentioned earlier. Doctors often test for gene mutations found in GIST tumors. Gene mutation testing essentially is taking a piece of your tumor, extracting DNA or RNA from it, and running it on what is called a gene-sequencing machine. cheshire mouldings budworth oak door
