One intronic SNV was present in each of the following genes: EGFR, ERBB4, KDR, SMO, CDKN2B, PTEN, PTPN11, RB1, AKT1, and ERBB2. In PIK3CA and FBXL18 genes, two intronic variants were present, and in the SND1 gene, three intronic variants were detected in the HBL tumor presented in this study. The gene discussed is CDKN2B; the disease is neoplasm.
