• Exome Sequencing Analysis of Cutaneous Squamous Cell Carcinoma

  The Exome Sequencing Analysis of Cutaneous Squamous Cell Carcinoma (SCC) study is a single-center cohort study. To identify recurrent genomic aberrations that might underlie the development of this malignancy, we performed whole exome sequencing on a series of SCC-normal pairs to distill a list of 336 candidate genes that were subsequently re-sequenced in 100 SCC-normal pairs with an average depth >1200X. This study also included whole-genome copy number analysis on 5 primary SCC with KNSTRN p.Ser24Phe and 5 histologically matched SCC with wild-type KNSTRN.

• Leveraging Extended Families for Cardiovascular Disease Genomic Discovery

  This study characterizes a large early onset atrial fibrillation family and identifies a rare causative mutation (R231H) in the KCNQ1 gene. The age of this mutation is ~5000 years, as estimated using IBD-coalescent methods. The geographic distribution and demographic history of the mutation is described. Induced pluripotent stem cell derived cardiomyocytes carrying the mutation have abbreviated action potential duration, indicating a gain-of-function. This data resource provides exome or whole genome sequencing data for six patients and RNA-seq data from the cardiomyocyte experiments.

• Genomic and Transcriptomic Markers Associated with Response to Immune Checkpoint Blockade

  The neoantigen presentation score (NEOPS) study was designed to better understand molecular determinants of response to immunotherapies, including pembrolizumab and nivolumab in stage III or IV melanoma patients. From this work, we developed a composite approach to predicting neoantigens (NEOPS), which takes into account additional escape mechanisms, including HLA LOH (human leukocyte antigen loss of heterozygosity) and the impact of deleterious mutations to the antigen presentation machinery (APM), yielding an improved prediction of response to immunotherapy compared to TMB (tumor mutational burden) or neoantigen burden alone.

• Genome Wide Association Study of Subjects with Myalgic Encephalomyelitis (ME)/Chronic Fatigue Syndrome (CFS)

  Myalgic encephalomyelitis, also known as chronic fatigue syndrome or ME/CFS, is a complex and heterogeneous disease that severely impacts the health and quality of life of those afflicted. Several lines of evidence support the possibility that ME/CFS development may involve a heritable component. In this pilot study, 42 cases that meet the diagnostic criteria of ME/CFS and 38 healthy controls were consented into this study. The goal of this study was to identify candidate polymorphisms that can be used for a large multi-center screening study.

• Next Generation Mendelian Genetics: Atypical Werner Syndrome

  Werner syndrome (WS) is an adult-onset progeroid syndrome characterized by accelerated aging. The International Registry of Werner Syndrome in the Department of Pathology, University of Washington, collects WS cases from all over the world. Classical WS is caused by WRN mutations. Those who do not carry WRN are categorized as "atypical Werner syndrome." A small subset of atypical WS is caused by LMNA mutations. There also are many cases whose causes are still unknown. The purpose of this study is to identify other causative gene(s) of atypical WS.

• Genome-Wide Characterization of Pancreatic Adenocarcinoma Patients Using Next Generation Sequencing

  In this study, we whole genome sequenced tumor/normal pairs from three pancreatic adenocarcinoma patients to separately characterize each patient with respect to somatic alterations. For 2 patients for whom tumor RNA was available, we also performed RNA sequencing to evaluate gene expression changes. While additional sequencing is needed to improve our understanding of the disease, the information acquired from this study contributes to our knowledge base on pancreatic cancer and helps to establish a foundation for identifying and developing more efficacious treatments for patients.

• Molecular Characterization of Response to Rectal Chemoradiation

  Pre-operative chemoradiation (CRT) followed by resection is the standard of care option for patients with locally advanced rectal adenocarcinoma. Pathologic downstaging after CRT is associated with improved outcomes, but molecular predictors of response are poorly understood. We performed whole exome sequencing, gene expression profiling, and immune infiltrate analysis on rectal adenocarcinoma tumors prior to neoadjuvant CRT (pre-CRT) and at the time of resection (post-CRT) in 17 patients to identify somatic mutations and derive molecular biomarkers distinguishing complete and excellent partial responders versus non-responders.

• A Prospective Study of Lifestyle, the Gut Microbiome, and Diverticulitis

  By leveraging a large-scale collection of stool specimens (Micro-N) within the Nurses' Health Study II, we performed shotgun metagenomic sequencing and untargeted metabolomics profiling among 121 case women with a diagnosis of diverticulitis requiring antibiotics or hospitalization, with each matched to a control woman without diverticulitis during the same time period accounting for age, race, and month of stool collection (total N=242). We found microbiome and metabolomic profiles differed in diverticulitis cases compared to controls. Data deposited include metagenomic sequencing data (after removing the human sequences) and metabolomics data.

• Subclonal diversification of primary breast cancer

  Cancers are ecosystems of genetically related clones, competing across space and time for limited resources. To understand the clonal structure of primary breast cancer, we applied genome and targeted sequencing to 295 samples from 49 patients’ tumors. The extent of subclonal diversification varied considerably among patients and encompassed many spatial patterns, including local growth, intraductal dissemination and clonal intermixture. Landmarks of disease progression, such as acquiring invasive or metastatic potential, arose within detectable subclones of antecedent lesions, suggesting that subclonal mutations could be relevant if actionable. No defined temporal order of mutation was evident, with the commonest genes, including PIK3CA, TP53, BRCA2, PTEN and MYC, mutated early in some, late in others, often exhibiting parallel evolution across subclones. Signatures of homologous recombination deficiency correlated with response to neoadjuvant chemotherapy. Thus, the interplay of mutation, growth and competition drives clonal structures of breast cancer that are complex, variable across patients and clinically relevant.

• Single-cell targeted DNA-sequencing and protein sequencing

  We performed single-cell targeted DNA sequencing (MissionBio) on 13 high hyperdiploid B-ALL patients at diagnosis to study the genetic heterogeneity. For a number of patients single-cell surface protein antibody sequencing was added (DAB-seq) to better characterize the different cell types. Furthermore, additional samples during treatment were collected and analysed for some patients. In this way we want to study the clonal heterogeneity of these B-ALL samples, based both on mutations and CNVs, and identify resistant clones that could be targeted after relapse.

• Molecular correlates for HPV-negative head and neck cancer engraftment prognosticate patient outcomes

  Head and neck squamous cell carcinoma (HNSCC) tumors were sampled from 88 patients. Samples were implanted subcutaenously into the flank of NOD/SCID/IL2R-/- mice. Mice were then monitored weekly for tumor growth and the time of initial palpation was recorded. Mice were euthanized when tumors reached 15 mm in diameter or after 6 months. If no tumor formed by 6 months, the patient tumor was defined as Non-engrafter (N). RNA-seq was performed on all primary tumor samples and successfully engrafted patient-derived xenograft (PDX) samples.

• Molecular counting enables accurate and precise quantification of methylated ctDNA for tumor-naive cancer therapy response monitoring

  Personalized cancer treatment can significantly extend survival and improve quality of life for many patients, but accurate and real-time therapy response monitoring remains challenging. To overcome logistical and technical challenges associated with therapy response monitoring via imaging scans or assays that track the variant allele fraction (VAF) of somatic mutations in circulating tumor DNA (ctDNA), we developed a tumor-naive liquid biopsy assay that leverages Quantitative Counting Template (QCT) technology to accurately and precisely quantify methylated ctDNA (Northstar ResponseTM).
