When subgroups were separated by diagnoses, 30 of 105 (28.6%) patients with hematologic malignancies had a VUS in a relevant gene associated with childhood onset (A2ML1, ADA, ATM, BLM, BRCA2, CREBBP, DDX41, DNAJC21, EFL1, EP300, ERCC6L2, FANCF, MAP2K2, PARN, PAX5, PTPN11, RPL5, RRAS, SH2D2A, SHOC2, SOS2, TERT, TNFRSF13B). This evidence concerns the gene CREBBP and hematologic disorder.
