• Acquisition of additional mutations drives accelerated progression of NPM1 positive CMML to AML

  This data is part of a pre-publication release. For information on the proper use of pre-publication data shared by the Wellcome Trust Sanger Institute (including details of any publication moratoria), please see http://www.sanger.ac.uk/datasharing/ We performed exome sequencing on serial samples from a patient with CMML who progressed to AML. The exome sequencing suggests that NPM1, TET2 and DNMT3a mutations were present in the dominant clone in the CMML sample and that NRAS is a new subclonal mutation in the AML sample. Diagnostic data shows the presence of a FLT3-ITD mutation in the AML sample, which is likely to have driven progression. Here we are performing re-sequencing of the putative driver and some passenger mutations which appear to be in the same clone to validate these mutations and to verify the relative quantification of these abnormalities .

• Targetable NOTCH1 rearrangements in reninoma

  Reninomas are exceedingly rare renin-secreting kidney tumours that derive from juxtaglomerular cells, specialised smooth muscle cells that reside at the vascular inlet of glomeruli. They are the central component of the juxtaglomerular apparatus which controls systemic blood pressure through the secretion of renin. We assessed somatic changes in reninoma and found structural variants that generate canonical activating rearrangements of NOTCH1, whilst removing its negative regulator, NRARP. Accordingly, in single reninoma nuclei we observed excessive renin and NOTCH1 signalling mRNAs, with a concomitant non-excess of NRARP expression. Re-analysis of previously published reninoma bulk transcriptomes further corroborates our observation of dysregulated Notch pathway signalling in reninoma. Our findings reveal NOTCH1 rearrangements in reninoma, therapeutically targetable through existing NOTCH1 inhibitors, and indicate that unscheduled Notch signalling may be a disease-defining feature of reninoma.

• A common single nucleotide variant in T is strongly associated with chordoma

  Chordoma is a rare malignant bone tumor that expresses the transcription factor T. We conducted an association study of 40 patients with chordoma and 358 ancestry-matched, unaffected individuals with replication in an independent cohort. Whole-exome and Sanger sequencing of T exons reveals a strong risk association ( allelic odds ratio (OR) = 4.9, P = 3.3x10-11, CI= 2.9-8.1) with the common (minor allelic frequency >5%) non-synonymous SNP rs2305089 in chordoma, which is exceptional in cancer genetics.

• Targeted sequencing (paired) of HR genes in primary and metastatic patient-derived xenografts (PDXs) of colorectal cancer (CRC)

  The dataset includes DNA targeted paired-wise (2 FASTQ per sample) sequencing of a manually curated panel of 44 genes with a documented role in homologous recombination (HR), a pathway of DNA damage response. Sequencing was conducted in 69 tumors from patients with metastatic colorectal cancer after serial passaging in mice (patient-derived xenografts, PDXs). For each PDX model profiled for HR gene mutations, therapeutic annotation of response to FOLFIRI (a chemotherapeutic regimen consisting of the combination of 5-fluorouracil and irinotecan) is available.

• Metabolism and Genetics of Hypobetalipoproteinemia

  Hypobetalipoproteinemia is characterized by extremely low levels of low-density lipoprotein cholesterol. Familial hypobetalipoproteinemia (FHBL) is a monogenic form of hypobetalipoproteinemia caused by mutations in the APOB gene. There are cases of hypobetalipoproteinemia not caused by mutations in APOB, however. The purpose of this study is to identify novel genetic causes of hypobetalipoproteinemia.

• Breakfast trial transcriptomic profiles

  The dataset consists in fastq files generated with RNA sequencing of 55 samples from 29 patients with stage I-III TNBC treated with anthracycline-taxane chemotherapy plus fasting-mimicking diet plus/minus metformin in the context of the BREAKFAST trial (NCT04248998). Samples are fresh-frozen tumor samples at baseline and 14-21 days after the first treament cycle sequenced to identify early predictors of treatment activity. Each sample is sequenced in multiple lanes (four or eight lanes each) and in paired ends mode (R1 and R2 fastq files). Samples were sequenced by an Illumina Nextseq500 platform.

• SF3B1 splicing signature

  We describe individuals with de novo pathogenic variants in SF3B1. SF3B1 is a core component of the U2 snRNP complex that ensures accurate branchpoint and 3′ splice-site recognition, and its mutations induce aberrant splicing that contributes to tumorigenesis, notably in myelodysplastic syndromes. We aim to study splicing defects associated with constitutional pathogenic variants.

• Partially methylated domains across multiple cell types

  Partially methylated domains are extended regions in the genome exhibiting a reduced average DNA methylation level. They cover gene poor and transcriptionally inactive regions and tend to be heterochromatic. We present a comprehensive comparative analysis of partially methylated domains in human and mouse cells, to identify structural and functional features associated with them.
