Genomic analysis (Altera Tumor Genomic Profile, Natera, Inc.)showed that the tumor had low tumor mutational burden (TMB, 2 mutations/megabase), was microsatellite stable (MSS), and had genomic alterations including APC (D170 loss of function mutation), APC (E1397 stop gain mutation), KRAS (G12D), and PIK3R1 (K447_Y452 deletion). Here, PIK3R1 is linked to neoplasm.
