Proteins in which the mutation clusters were identified with the most significant P‐values were cancer drivers for which it was previously shown that mutations in their interfaces can lead to disease development by disrupting interactions with regulatory proteins (PIK3CA and PPP2R1A) or by preventing GTP hydrolysis (KRAS, HRAS, and GNAS); Dataset EV9, 87 proteins in total. Here, KRAS is linked to cancer.
