• Genomic features of renal cell carcinoma developed in end-stage renal disease and dialysis

  Patients with end-stage renal disease (ESRD) or receiving dialysis have 3 ���24-fold higher risk for renal cell carcinoma (RCC). Long-term hemodialysis cause acquired cystic disease (ACD) and RCC.���But its carcinogenic mechanism and genomic features are not so clear. In this study, we analyzed whole genome and transcriptome of 38 RCCs, which were developed in ESRD patients receiving dialysis and characterized their genomic features and associations with their histology and dialysis or end-stage renal diseases.

• Targeted exome sequencing identify compound heterozygous TYK2 mutations in patients with primary immunodeficiency who developed EBV-associated lymphoma

  In this study, we evaluated 2 siblings with primary immunodeficiency who developed EBV-associated lymphoma. Immunophenotyping of PBMCs revealed that both patients had significant T cell lymphopenia characterized by low na?ve CD4+ T cell counts. To identify the causative genetic mutations in the patients, we performed targeted exome sequencing using the Illumina MiSeq on the patients and their parents. The results showed a novel compound heterozygous mutations in the gene encoding tyrosine kinase 2 (TYK2) in the patients.

• Mutational Spectrums and Clinical Features of Patients with LOXHD1 Variants Identified in a 8,074 Hearing Loss Patient Cohort.

  Variants of LOXHD1 gene, which are expressed in hair cells of the cochlea and vestibule, have been reported to cause a progressive form of autosomal recessive non-syndromic hereditary hearing loss, DFNB77. In this study, genetic screening was conducted on 8,074 Japanese hearing loss patients utilizing the massively parallel DNA sequencing, to identify individuals with LOXHD1 variants and to assess their phenotypes. 28 affected individuals and 21 LOXHD1 variants were identified, among which 13 were novel variants.

• WES sequencing of metastatic colorectal cancer patient-derived xenografts with known response to irinotecan.

  Chemotherapy is the standard-of-care treatment for metastatic colorectal cancer (mCRC) and benefits some patients, but what distinguishes responders from non-responders is unclear. In this study, we expand a pre-existing collection (https://doi.org/10.1158/2159-8290.CD-24-0556) of molecularly annotated patient-derived xenografts to uncover functional predictors of response to 5-FU and irinotecan combination therapy (FOLFIRI) in mCRC. We complemented previous mutational profiles with whole exome sequencing for 46 xenografts with known response to irinotecan.

• Spatial Profiling of Patient-Matched HER2 Positive Gastric Cancer Reveals Resistance Mechanisms to Trastuzumab and Trastuzumab Deruxtecan Sequencing

  HER2-positive gastric cancer (HER2+ GC) exhibits significant intra-tumoral heterogeneity and frequent development of resistance to HER2-targeted therapies. This study aimed to characterize the spatial tumor microenvironment (TME) and identify mechanisms of resistance to HER2 blockade including trastuzumab and trastuzumab deruxtecan (T-DXd) in HER2+ GC, with the goal of informing novel therapeutic strategies. We performed spatial transcriptomics on pre- and post-treatment samples from patients with HER2+ metastatic GC who received trastuzumab-based therapy.

• A 3D genome atlas of breast cancer progression (BRCA3D)

  In this study, we aimed to understand how the 3D genome changes during breast cancer development and progression, in situ. Towards this goal, we collected cells from patient biopsies and performed Hi-C on four types of biopsies representing different stages of disease progression: healthy mammary tissue, primary breast tumours, liver metastasis and malignant pleural effusions. We survey the changes in the 3D genomes at the level of structural variation, compartments and TADs, as well as ERα associated distal interactions.

• Mutational spectrum of highly differentiated, fusion-negative rhabdomyosarcoma (set 1).

  Pediatric PAX-FOXO1 fusion-negative rhabdomyosarcoma represents a diverse spectrum of tumors. In this study, the mutational spectrum of 22 fusion-negative rhabdomyosarcomas with high, rhabdomyoma-like levels of differentiation was evaluated using OncoPanel v.2 (OPv2), an Agilent SureSelect custom designed bait set consisting of the coding regions of 504 cancer-relevant genes. Corresponding normal tissue was not available. Discarded normal human skeletal muscle, obtained from 7 donors without tumor history, were also included in the sequencing run.

• Combined targeting of BRD4-associated Promoter Activation and NFKB Immunomodulation in ARID1A-mutated Gastric Adenocarcinoma

  Gastric cancer (GC) a leading causes of cancer-related deaths worldwide, with ARID1A identified as the second most frequently mutated driver gene in GC. This study involves comprehensive genomic profiling of a Singaporean cohort of over 200 GC patients to characterize the mutational signatures associated with ARID1A inactivation across various molecular subtypes of GC. The findings highlight a potential therapeutic approach for ARID1A-mutated GCs, targeting both tumor-intrinsic mechanisms (BRD4-associated promoter activation) and extrinsic immunomodulatory pathways (NFKB signaling).

• Melanoma_TIL_Study_Exomes

  In this study, mutations present in a series of human melanomas (stage IV disease) will be determined, using autologous blood cells to obtain a reference genome. From each of teh samples that are analyzed, tumour-infiltrating T lymphocytes have also been isolated. This offers a unique opportunity to determine which (fraction of) mutations in human cancer leads to epitopes that are recognized by T cells. The resulting information is likely to be of value to understand how T cell activating drugs exert their action.

• Next generation sequencing of sporadic schwannomatosis samples

  Schwannomatosis (MIM #162091) is characterized by the development of multiple schwannomas without vestibular nerve involvement (which is a characteristic of neurofibromatosis type 2 - NF2). In an effort to detect novel genetic alterations predisposing to schwannomatosis, we sequenced eight tumor-blood DNA pairs from de novo schwannomatosis patients. The results of our study are present in the paper "Whole exome sequencing reveals that the majority of schwannomatosis cases remain unexplained after excluding SMARCB1 and LZTR1 germline variants" published in Acta Neuropathologica (PMID:25008767)

• Targeted sequencing of brain expressed miRNA genes

  As regulators of gene expression, microRNAs (miRNAs) are likely to play an important role in the development of disease. In this study we present a large-scale strategy to identify miRNAs with a role in the regulation of neuronal processes by screening 289 brain expressed miRNAs. Thereby we found variant rs7861254 located near the MIR204 gene to be significantly associated with schizophrenia. This variant resulted in reduced expression of miR-204 in neuronal-like SH-SY5Y cells.

• Hip OA Functional Genomics

  The aim of this work is to apply an integrated systems approach to understand the biological underpinnings of hip osteoarthritis that culminates in the need for total joint replacement (TJR). This study is a feasibility pilot that integrates functional genomics data from diseased and non-diseased tissues of OA patients who have undergone TJR. For each tissue, we characterised epigenetic marks (methylation), gene transcription (RNASeq) and expression (quantitative proteomics). We also generated genotype data on the HumanCoreExome array for each individual.

• Colorectal adenomas and carcinomas NKI-AvL TGO series Gut2009

  Colorectal cancer (CRC) develops from normal epithelium, through a benign precursor lesion called adenoma, by accumulation of genetic alterations affecting oncogenes and tumour suppressor genes. These CRC-related genomic alterations often result in specific RNA-expression patterns. RNA isolated from fresh frozen specimen of 32 adenomas and 29 CRCs was obtained from the previously published study (Carvalho et al. 2009) and RNA-sequencing was performed with the aim to examine RNA expression changes in colorectal adenoma-to-carcinoma progression.
