Additional somatic mutations affecting cancer‐ genes found in MEC included NF1/2, structure‐specific endonuclease subunit (SLX4), and Notch homolog 1, and translocation‐associated (NOTCH1) in 2 (25%) cases as well as AKT1, SWI/SNF‐related matrix‐associated actin‐dependent regulator of chromatin subfamily B member 1 (SMARCB1), KRAS, and BRCA2 in 1 (13%) case, respectively. This evidence concerns the gene SLX4 and cancer.
