• Sequencing data from a phase II study of nivolumab and ipilimumab in recurrent or refractory cancer of unknown primary (CheCUP trial)

  Sequencing data from a phase II study of nivolumab and ipilimumab in recurrent or refractory cancer of unknown primary (CheCUP trial). Panel sequencing data from baseline FFPE biopsies were used to perform a comprehensive genomic profiling of CUP metastases. Combined targeted next-generation sequencing of patient-specific hotsport mutations and shallow whole genome sequencing of baseline and follow-up liquid biopsy samples were used to analyze ctDNA and to evaluate response to immunei checkpoint inhibitor treatment. In some cases, whole exome sequencing of peripheral blood mononuclear cells was performed to screen for potential CHIP and germline mutations.

• Direct transcriptional consequences of somatic mutation in breast cancer

  The disordered transcriptomes of cancer encompass direct effects of somatic mutation on transcription; co-ordinated secondary alterations in transcriptional pathways; and increased transcriptional noise. To catalogue the rules governing how somatic mutation Overall, 59% of 6980 exonic substitutions were expressed. Compared to other classes, nonsense mutations showed lower expression levels than expected with patterns characteristic of nonsense-mediated decay. 14% of 4234 genomic rearrangements caused transcriptional abnormalities, including exon skips, exon reusage, fusion transcripts and premature poly-adenylation. We found productive, stable transcription from sense-to-antisense gene fusions and gene-to-intergenic rearrangements, suggesting that these mutation classes may drive more transcriptional disruption than previously suspected. Systematic integration of transcriptome with genome data therefore reveals the rules by which transcriptional machinery interprets somatic mutation.

• DAC for Breast Invasive Lobular Carcinoma CDH1 study

  We developed an artificial intelligence (AI)-model applied to histological images trained using CDH1 biallelic mutations, pathognomonic for breast invasive lobular carcinoma (ILC), as ground truth. We evaluated the performance of the AI-model to predict the presence of CDH1 biallelic mutations and to diagnose ILC. Subsequently, we investigated the molecular underpinning of cases predicted by the model to harbor a CDH1 biallelic mutations but lacking these alterations according to targeted sequencing. We then subjected one ILC lacking CDH1 biallelic mutations and lacking CDH1 promoter methylation to whole genome sequencing (WGS) to determine the molecular basis of its lobular phenotype.

• Human CMV-specific CD8+ T cells

  In this study we established a comprehensive workflow to collect multi-omics single-cell data using a commercially available micro-well based platform. This included whole transcriptome, cell surface markers (targeted sequencing-based cell surface proteomics), T cell specificities, adaptive immune receptor repertoire (AIRR) profiles and sample multiplexing. With this technique we identified novel paired T cell receptor sequences for three prominent human CMV epitopes. In addition, we review the ability of dCODE dextramers to detect antigenspecific T cells at low frequencies by estimating sensitivities and specificities when used as reagents for single-cell multi-omics.

• NGS-Based Mutational Analysis of 87 PMBL Patients from the GAINED Cohort (Subset of 382 Sequenced Patients)

  Targeted DNA sequencing was performed on DNA extracted from 87 formalin-fixed paraffin-embedded (FFPE) samples, representing a subset of the 382 sequenced patients from the GAINED cohort. A custom “Lymphopanel” was used to identify mutations in 70 genes associated with lymphomagenesis. Library preparation, exome capture, sequencing, and analysis were conducted by IntegraGen SA (Evry, France). Sequencing was performed on an Illumina HiSeq4000 platform, with variant calling and annotation using established bioinformatics tools such as MuTect and VEP.

• Whole-genome sequencing data of poorly differentiated thyroid carcinomas and matched blood from six patients

  This dataset contains raw sequencing reads in FASTQ format from 12 samples, comprising paired tumour and matched blood DNA from six patients diagnosed with poorly differentiated thyroid carcinoma (PDTC). Genomic DNA was extracted from fresh-frozen tumour tissue and peripheral blood using standard protocols. Whole-genome sequencing was performed on the Illumina HiSeq X Ten platform, generating paired-end reads at an average depth of approximately 20X. These data support investigations into the somatic mutational landscape and genomic alterations associated with PDTC.

• Sanger sequencing analysis data using cfRNA from plasma samples in 6 cases, 10 samples, all from sarcoma.

  We examined the levels of cfRNA in the blood of patients with malignant bone and soft tissue tumours harbouring specific fusion genes, to explore the relationship between fusion gene expression in the blood and therapeutic response and disease status, and to validate the clinical utility of liquid biopsy.

• Emirati Haploid Single-Sample-Assemblies (30 Individuals, 60 Assemblies)

  This dataset provides 27 phased diploid genome assemblies for Emirati trios, delivered in FASTA format. Assemblies were built with hifiasm (trio mode) from PacBio HiFi reads at ≥25× coverage for each parent and offspring, then scaffolded with NTLink and reference-guided merging using RagTag against CHM13v2. As part of the same program, a complementary set of single-sample diploid assemblies for 30 individuals (yielding 60 haplotypes) is being generated from deep PacBio HiFi data to expand a population-matched pangenome reference. Together, these resources capture Emirati genomic diversity and support downstream variant discovery and annotation.

• WES for 42 patients with pleural mesothelioma (Not matched)

  The dataset contains WES data (bam files) for 42 pleural mesothelioma samples. Nextera Flex for Enrichment solution (Illumina, San Diego, CA) in combination with SureSelect Human All Exon V7 probes (Agilent, Santa Clara, CA) was used for library preparation and generated libraries were sequenced on NovaSeq 6000 (Illumina, San Diego, CA) in 150 pair-end mode. Quality control of the raw data was conducted using fastQC (v. 0.11.8) (https://www.bioinformatics. babraham.ac.uk/projects/fastqc/). WES data were then analyzed with the DRAGEN Bio IT platform 49 (version 4.2.4) and the human GRCh38 as reference genome.
