• Fragmentomics analyses of urinary cfDNA for urologic cancers

  This dataset contains sequencing data of human urinary cell-free DNA. Whole-genome sequencing (WGS) and whole-genome bisulfite sequencing (WGBS) was performed after DNA extraction from the urine samples. All samples were pair-end sequencing on Illumina system and were aligned to human genome GRCh37 (hg19). WGS and WGBS reads were aligned by SOAP2 and Methyl-Pipe, respectively. The dataset includes samples from healthy subjects, haematuria (non-cancer), and patients of bladder, kidney, or prostate cancer. Pair-end FASTQ files were provided for all the samples mentioned above.

• A higher ctDNA fraction decreases survival in regorafenib-treated metastatic colorectal cancer patients

  The predictive effect of circulating tumor DNA (ctDNA) in colorectal cancer (CRC) treatment is still highly discussed. The primary objective of this study was to investigate a possible prognostic/predictive value of ctDNA under regorafenib treatment. This prospective multicenter translational biomarker phase II pilot study enrolled 30 metastatic CRC patients (67% men, 33% women) treated with regorafenib. ctDNA was assessed in plasma before treatment start and at defined time points during administration. Measurement of tumor fraction as well as mutation and copy number analysis of CRC driver genes were performed by next generation sequencing approaches. Multivariate analyses for survival and treatment efficacy were adjusted to age, gender and ECOG. Disease control rate was 30%. Median tumor fraction at baseline was 18.5% (0-49.9). Mutations in CRC driver genes or genes involved in angiogenesis were identified in 25 patients (83.3%). KRAS mutations were detected in 13 out of 14 KRAS positive tumors, in three patients without KRAS mutation in the respective tumor acquired mutations as a consequence of prior anti-EGFR treatment were detected. In a subset of patients, novel occurring mutations or focal amplifications were detected. A tumor fraction of 5% and higher at baseline was significantly associated with a decreased OS (p=0.022; HHR 3.110 (95%CI: 1.2-8.2). ctDNA is detectable in a high proportion of mCRC patients. Higher ctDNA levels are associated with survival among regorafenib treatment. Moreover, our data highlight the benefit of a combined evaluation of mutations and somatic copy number alterations (SCNA) in advanced cancer patients.

• Fragmentomic features of individuals with different cfDNA concentrations

  The goal of this study is to explore fragmentomic patterns that vary between individuals of different concentrations of total cell-free DNA in plasma. We have selected a large cohort of individuals (ethnically Chinese men with a median age of 54 years, IQR 49-57) who were part of a screening of a large-scale clinical study to screen for nasopharyngeal carcinoma. Differences in fragmentomic features provided insights into the modulation of cfDNA levels in blood circulation. Fragmentomic and machine learning systems adopted in this study have also been applied to assess the quantity of cfDNA species of clinical interest, including the fraction of circulating fetal and tumor DNA, from pregnancy cases and individuals with hepatocellular carcinoma, respectively.

• Transrenal DNA Analysis

  The current sequencing dataset consists of 91 whole genome sequencing data files (Fastq files) of human cell-free DNA (cfDNA) obtained from plasma and urine samples. Specifically, we extracted 20 ucfDNA and 17 plasma DNA samples from healthy pregnant women, 11 ucfDNA samples from pregnant women with preeclampsia, 19 ucfDNA samples from healthy controls, and 24 ucfDNA samples from patients with proteinuria. These extracted cfDNA samples were then constructed into DNA libraries using the TruSeq Nano DNA Library Prep Kit (Illumina) and subsequently sequenced on the Nextseq2000 platform (Illumina).

• WGS data of pediatric T-ALL acute lymphoblastic leukemia (set3)

  The dataset includes FASTQ and CRAM files from diagnostic and matched remission (control) samples of two T-ALL patient (ALLK-126, ALLT-503). ALLT-503 sample has two diagnostic samples one extracted from the BM (ALLT-503D) and from the lymph node (ALLT-503lympD). Sequencing library was made using PCR free-based WGS library preparation (PCR-), using Novogene NGS DNA Library Prep Set (Cat No. PT004). Both diagnostic/relapse (90x) and remission (30x) samples were sequenced using Illumina NovaseqX Plus.

• Papua New Guinean Lowlanders dataset

  The Papua New Guinean Lowlanders dataset includes 41 whole genome sequences for Papua New Guinean individuals sampled in Daru. DNA was extracted from saliva samples (Oragen kit). Sequencing libraries were prepared using the TruSeq DNA PCR-Free HT kit. 150 bp paired-end sequencing was performed on the Illumina HiSeq X5 sequencer. The PGAP dataset provides Fastq, mapped cram files (GRCh38) and phenotype measurements.

• Whole genome sequence of monozygotic twins

  We generated whole genome sequence data from a family of monozygotic twins. DNA was obtained from blood, buccal epithelial cells, placenta, and umbilical cords of monozygotic twins. DNA from the parents were also obtained. Libraries were generated using Truseq-PCR free, Truseq nano, and NEBnext Ultra II depending on the availability of DNA. Data was generated on Illumina NovaSeq platform. Raw sequence data was aligned to the human reference genome GRCh38 using bwa mem aligner.

• RNA sequencing in blood samples of cluster headache patients

  Cluster headache is a relatively rare headache disorder, typically characterized by multiple daily, short-lasting attacks of excruciating, unilateral (peri-)orbital or temporal pain associated with autonomic symptoms and restlessness. To better understand the pathophysiology of cluster headache, we used RNA sequencing to identify differentially expressed genes and pathways in whole blood of patients with episodic (n = 19) or chronic (n = 20) cluster headache in comparison with headache-free controls (n = 20).

• Study of Controlled Human Malaria Infections to Evaluate Protection After Intravenous or Intramuscular Administration of PfSPZ Vaccine in Malaria-Naive Adults

  The study was performed to evaluate whole-blood transcriptomic profiles via RNA-seq before, during, and after immunization with the PfSPZ Vaccine in malaria-naïve, health adults enrolled in VRC 314 (NCT02015091). VRC 314 was designed as an open-label evaluation of the safety, tolerability, immunogenicity, and protective efficacy of the PfSPZ Vaccine. This study was designed to substantiate the initial results with the IV vaccination route for protection against CHMI that was observed in VRC 312 (NCT01441167). Based on the potential importance of dose and schedule in optimizing sustained immunity with this vaccine, an increase in PfSPZ IV dosage on schedules of 3 to 5 vaccinations was evaluated for protection against CHMI conducted early (about 3 weeks) and late (about 24 weeks) after completion of vaccinations. To assess if a higher dose given by another route confers protection, one group received PfSPZ IM, with half of the amount administered in each arm on a schedule with 4 vaccination. The primary objectives of the study were related to the safety and tolerability of vaccinations by the IV and IM routes of administration and protection against Plasmodium falciparum (Pf) challenge performed via a well-established CHMI procedure early (2-4 weeks) after completing schedules of 3 to 5 vaccinations. The secondary objective was related to the durability of protection at 20-26 weeks after the last vaccination, and exploratory objectives were related to the immunogenicity of the PfSPZ Vaccine and identifying potential immune correlates of protection. To further determine potential molecular correlates of immunogenicity and/or protection, RNA-seq was performed on whole blood collected from subjects in all dose groups at time points before, during, and after immunization.
