We found a structural aberration on the long arm of chromosome 3 (3q) with amplifications of the genes PIK3CA, SOX2, and FGF12; mutations of TP53, ATRX1, RB1, and, subclonally, PIK3CA; a stable microsatellite state (MSS), and a low tumor mutational burden (5 Muts/Mb). This evidence concerns the gene PIK3CA and neoplasm.
