Mutational patterns in panNETs ≤2 cm and >2 cm. (A) The number of mutations identified in panNETs >2 cm is significantly higher than in smaller tumors. In particular, panNETs >2 cm in diameter are enriched in mutations of DAXX. The overall rate of mutations of MEN1, DAXX and TSC2 was 21.4%, 14.3% and 12.5% respectively. The asterisk marks statistical significance as defined by p ≤ 0.05. (B) The driver plot displays the somatic mutations identified in panNETs ≤2 cm (n = 27) and > 2 cm (n = 29). Of the 19 genes sequenced, 3 genes (MLL3, DIS3L2, URGCP) were always wild-type, and therefore are not represented in the plot.
