• Solve-RD multi-omics data chud-faivre cohort

  The dataset includes short-read whole-genome sequencing (SR-WGS) data, SR-RNAseq data, OGM (Bionano) data, LR-WGS data, Epigenetics (RBSS) data and deep-WES data generated within the project Solve-RD from biosamples submitted by the group chud-faivre. The cohorts consists of 111 individuals recruited as part of Solve-RD cohorts 2-4 and aligns with ERN-ITHACA related disease entities (for a description of the Solve-RD cohorts see www.solve-rd.eu/fact-sheet-solve-rd-cohorts).

• On-target mutations confer resistance to WRN helicase inhibitors in Microsatellite Unstable Cancer Cells

  This study investigates genetic dependencies and resistance mechanisms to Werner helicase inhibitors (WRNi) in microsatellite-unstable (MSI) cancer models. To define determinants of WRN dependency and acquired resistance, we performed genome-wide CRISPR-Cas9 knockout screens, CRISPR base-editing mutagenesis screens targeting WRN, targeted sequencing of resistance-associated variants, bulk RNA sequencing, and whole-genome sequencing. The datasets deposited in EGA comprise raw sequencing files from CRISPR-Cas9 knockout screens, CRISPR base-editing screens, targeted DNA sequencing, RNA-seq experiments, and whole-genome sequencing of parental and drug-treated cell populations, including models with spontaneously acquired resistance. These data enable investigation of WRN synthetic lethality, genetic modifiers of WRNi response, and genomic alterations emerging under selective pressure.

• Molecular QTLs of Human umbilical vein endothelial cells (HUVECs)

  We aim to characterise the range of phenotypic variation in gene expression, epigenetic regulation and intermediate functional phenotypes and its underlying genetic determinants in primary Human umbilical vein endothelial cells (HUVECs) samples We will measure gene expression by RNA sequencing (RNA-seq), genome functionality by ATAC-sequencing (ATAC-seq, to determine which regions are in an open chromatin state) and by determining H3 lysine 27acetylation (H3K27ac), a marker of active transcriptional enhancers, localisation genome wide by chromatin immunoprecipitation coupled with sequencing (ChIP-seq).

• Association of OXTR and AVPR1A Genetic Variation with Empathy and Dark Triad Traits in a Non-Clinical Human Sample

  This study investigates associations between variation in OXTR and AVPR1A, empathy, and Dark Triad personality traits in 506 participants from a non-clinical human sample. OXTR rs53576 and rs2254298 were genotyped using TaqMan assays, while AVPR1A RS1 and RS3 microsatellites were characterized by capillary electrophoresis and fragment-length analysis. Empathy was assessed using the Interpersonal Reactivity Index (IRI), and Machiavellianism, narcissism, and psychopathy were assessed using the Short Dark Triad (SD3). The study evaluates direct genotype–phenotype associations and indirect associations involving specific dimensions of empathy.

• Genomic evolution and natural history of myeloproliferative neoplasms on therapy - triple-negative-ET

  Philadelphia-negative myeloproliferative neoplasms are chronic blood neoplasms. Treatments control blood counts but disease can progress to myelofibrosis or acute myeloid leukaemia. We performed longitudinal whole-genome and targeted sequencing in 30 patients, integrating clonal dynamics with 7,986 blood counts and clinical histories. Distinct evolutionary patterns distinguished stable from progressive disease, with leukaemic transformation arising via TP53 loss, stepwise driver mutation acquisition within complex clones, or emergence of independent leukaemic clones. In contrast, stable disease showed long-term clonal equilibrium without new drivers. Phylogenetic analysis using 203 whole-genomes of haematopoietic colonies revealed age-appropriate polyclonal haematopoiesis in triple-negative essential thrombocythaemia and germline predisposition to thrombocytosis, supporting non-neoplastic origins. Therapy-associated mutagenesis was observed, including C>G mutations following azacitidine and characteristic T>A/T>G after hydroxycarbamide exposure in blood cells, although not in skin where UV damage predominated. These findings demonstrate progression is genomically encoded years in advance and support serial monitoring and further study of treatment-related mutagenesis.
