  Acute leukemias are the most common malignancies in children with an onset of the disease among 0-6 years-old. The early development of theses malignancies has been proposed as an indicator of their prenatal origin, hypothesis that has been confirmed especially in the case of acute lymphoblastic leukemia. For acute myeloid leukemia (AML), comprising an heterogenous group of different cytogenetics subtypes, this prenatal origin has also been confirmed specially for MLL-rearranged and t(8;21) subgroups. AMLs carrying t(7;12) constitute up to 30% of cases under 2-years-old, frequently being associated with a trisomy of chromosome 19 and an overexpression of MNX1 gene. An in utero origin of this specific subgroup has been suggested but not clearly confirmed. Here, we present the case of a 5-months-old AML patient with t(7;12) in which we have fully characterized a novel breakpoint occurring among ETV6 and NOM1 genes. We demonstrate the presence of this specific ETV6-NOM1 fusion in CD34+ hematopoietic stem and progenitor cells isolated from the cord blood unit from the same patient and stored at birth. Moreover, trisomy +19 present at diagnosis was not detected at birth. Together, our results demonstrate the prenatal origin of the t(7;12) in infant AML, and establish trisomy +19 as a secondary event in this leukemia.

• Targeted deep sequencing on Pediatric MDS

  Targeted NGS using custom panels with SAMD9, SAMD9L genes and 22 single nucleotide polymorphisms (SNP) on chromosome 7q (allele frequency >35% in all ethnic sub-populations in gnomAD) (Ampliseq #IAD10417) was performed in 667/669 cases. Additionally, 559 cases were sequenced using 28 pediatric MDS genes (GATA2, RUNX1, HOXA9, CEBPA, GATA1, KRAS, NRAS, CBL, PTPN11, ASXL1, EZH2, SETBP1, FLT3, KIT, JAK2, JAK3, CSF3R, MPL, SH2, BCOR, BCORL1; RAD21, STAG2, CTCF, TP53, PTEN, CALR, VPS45; Ampliseq #IAD51150). Libraries for targeted NGS were prepared using NEBNext Ultra II DNA library prep kit (New England BioLabs, cat#E7645S/L) per manufacturer’s instruction and samples were sequenced on an Illumina Miseq 2000 with 2 x 150 bp reads. The BAM files are uploaded here.

• Genomic characterization of hepatocellular carcinoma in Hispanic patients

  The genomic DNA was extracted from paired tumor and adjacent non-tumor samples of 27 Hispanic HCC patients. The TruSeq Rapid Exome Library Prep kit (Illumina, CA) was used to capture the coding regions of the human genome. The 100 bp paired-end sequencing of every 6-plex whole exome library pool was performed on an Illumina HiSeq 3000 system according to the manufacturer’s recommended protocol to achieve an average coverage of ~100X. The paired-end reads were aligned to the human reference genome (hg19) with decoy sequences (as used in the 1000 Genomes Project) using BWA software. The duplicate reads were marked and removed using Picard and SAMtools, respectively. Local realignment around insertions/deletions (indels) and base quality recalibration were performed using GATK.

• Primary plasma cell leukemia (pPCL) samples were sequenced using the Nimblegen MedExome hybridization capture to detect translocations, copy number changes, and mutations in 20 pPCL samples and patient matched controls.

  Primary plasma cell leukemia (pPCL) is a rare malignancy related to multiple myeloma. Here we have assembled 20 patient samples and performed whole exome sequencing to determine the differences between multiple myeloma and pPCL. CD138+ cells were purified from bone marrow aspirates from patients with pPCL. Control cells were obtained from CD34+ stem cell harvests or CD3+ T cells. DNA was extracted and processed using the HyperPlus library prep kit (KAPA Biosystems) and sequenced using 75 bp paired end reads on an Illumina NextSeq500.

• High Sensitivity ctDNA Analysis Using a Novel Panel and NOIR-SS Technology for Monitoring Advanced Urothelial Carcinoma

  This dataset contains sequencing data generated by targeted amplicon analysis using the NOIR-SS method in 15 patients with advanced urothelial carcinoma. Formalin-fixed paraffin-embedded (FFPE) tumor tissues (15 samples) and plasma cfDNA (50 samples) were analyzed. Tumor tissues were subjected to targeted panel sequencing to identify mutations in TP53, FGFR3, TERT, and KRAS/HRAS. Plasma cfDNA was analyzed using a tumor-informed approach focusing on the mutations identified in matched tumor tissues. Sequencing was performed on the Ion PGM or Ion S5 XL platform. Raw sequencing data are provided in FASTQ format under controlled access.

• Multiomic characterization of clonotypic B cells

  DNA was purified using AMPure XP magnetic beads (Beckman Coulter [BC] Life Sciences, Indianapolis, IN) and its quality was evaluated in an Agilent 4200 Tapestation using the Genomic DNA ScreenTape system (Agilent, Santa Clara, CA). DNA was quantified using the Qubit System (Invitrogen). Extracted DNA from AL patients was fragmented to 200bp by a Covaris S220 ultrasonicator (Covaris, Woburn, MA) and used to generate and capture libraries following the manufacturer’s indications from Twist Bioscience’s Human Core Exome Enrichment Kit (Twist Bioscience). Extracted DNA from MM patients and HA was fragmented to an average size of 225 bp using a Covaris S220 ultrasonicator (Covaris, Woburn, MA) and subjected to DNA library construction using Chromium Genome Reagent Kit V2 for Exome Assays (10X Genomics). Target enrichment was performed with SureSelectXT Human All Exon V6 Capture Library (Agilent) or SureSelectXT2 Human All Exon V5+UTRs (Agilent), and sequence targets were captured and amplified in accordance with the manufacturer’s protocol. Final libraries were combined with standard Illumina sequencing primers and paired-end sequenced (150bp) on a HiSeq X platform (Illumina, CA) or in a NovaSeq 6000 (Illumina).
