Table 2 summarizes the frequently altered genes in the study population according to tumor type. ARID1A was one of the genes included in the 144 gene panel and was seen in four cases; one clear cell carcinoma showed ARID1A alterations along with KDM, PPP2R1A, R183W, M2055, Q515, Q147. The other three cases were high-grade serous carcinomas that showed ARIDA1 along with TP53 alterations. This evidence concerns the gene PPP2R1A and neoplasm.
