CDKN2A and adenoid cystic carcinoma: Our results in adenoid cystic carcinoma (Figure 1B) are in agreement with previously reported literature where several aberrations including NOTCH1/2 (3/24 [12.5%]), KDM6A (2/24 [8.3%]), CDKN2A (1/24 [4.2%]) and PIK3CA (1/24 [4.2%]) were identified by whole exome sequencing of 24 patients with adenoid cystic carcinoma [47].
