• The Genomic Landscape of Tuberous Sclerosis Complex (TSC)

  In this study, we characterized the genomic landscape of tuberous sclerosis complex (TSC), a rare genetic disease causing multisystem growth of benign tumors and other hamartomatous lesions. We analyzed 127 human tissues, including 111 TSC-associated samples and 16 non-TSC negative controls, using multiple genomic platforms including whole exome sequencing, targeted sequencing of known disease-causative loci (TSC1 and TSC2), mRNA sequencing, high-density SNP arrays, and DNA methylation arrays.

• Identification of Structural Variants Relevant to Autism by Pacific Biosciences HiFi Whole-Genome Sequencing

  The purpose of this research study was to perform long-read whole-genome sequencing on a family with autism. This family had no known genetic cause based on clinical array and whole-exome sequencing analysis. Utilizing PacBio HiFi long-read whole-genome sequencing, we identified a relevant missense variant in the KCNC2 gene. This variant was likely to be a germline mosaic in the paternal germline.

• ZRSR2 Mutant Myelodysplastic Syndromes

  Mutations in splicing factor genes are common in myelodysplastic syndromes but the reason for selection of these mutations remains incompletely understood. This study aimed to identify the effect of minor intron retention due to ZRSR2 mutations in myelodysplastic syndromes. Nine samples from patients with myelodysplastic syndromes bearing ZRSR2 mutations and ten samples from patients with myelodysplastic syndromes not bearing any splicing factor mutations were subjected to transcriptomic analysis for mis-splicing events after RNA-sequencing.

• Improved T Cell Immunity Following Neoadjuvant Chemotherapy in Ovarian Cancer

  This study characterized the evolution of the peripheral immune cell function and composition across the course of standard of care platinum and taxane chemotherapy in ovarian cancer using bulk and single cell transcriptomic approaches. Serial blood samples were collected from ten patients with advanced high-grade serous ovarian cancer treated with chemotherapy. Single cell sequencing was performed on five patients' samples collected before the initiation of chemotherapy and after the third cycle of chemotherapy.

• The PUWMa (

  The PUWMa GWAS of ADHD is a multi-site collaboration initiated to conduct a family-based association study from existing research samples. The source sample of ADHD families was ascertained at Massachusetts General Hospital (MGH, N=309 trios), Washington University at St. Louis (WASH-U, N=272 trios), and University of California at Los Angeles (UCLA, N=156 trios). All offspring met criteria for DSM-IV-TR attention-deficit hyperactivity disorder with childhood onset.

• Prospective Procurement of Solid Tumor Tissue to Identify Novel Therapeutic Targets

  Recent advances and insights into the molecular pathogenesis of cancer have led to the development of novel molecular and biologic targeted therapies for the treatment of advanced cancer patients. A critical challenge in extending these studies involves the identification and validation of new therapeutic targets for future cancer therapies. In this study, we performed whole exome and RNA-Seq analysis metastases to determine the nature and frequency of somatic mutations.

• Discovery, Biology, and Risk of Inherited Variants in Breast Cancer (DRIVE) - germline whole genome sequencing

  This study consists of whole genome sequencing (target: average 30x coverage) of 110 European-ancestry (EA), early-onset, family-history-positive breast cancer cases, 21 Asian cases, 25 African-American cases, and 24 controls from six studies participating in the Discovery, Biology, and Risk of Inherited Variants in Breast Cancer (DRIVE) consortium, part of the NCI's Genetic Associations and Mechanisms in Oncology (GAME-ON) initiative ( http://epi.grants.cancer.gov/gameon/ )

• Germline Sequencing for Aggressive Prostate Carcinoma

  This study aims to elucidate the genetic determinants of susceptibility to aggressive prostate carcinoma. To this end, germ line whole exome sequence has been generated from patients with aggressive prostate cancer. Whole genome sequence for a representative subset of tumors from patients whose cancer was resistant to primary therapy is included as well. This deep genomic interrogation will allow the identification of rare, functionally disruptive variants that may play a role in disease progession and response to treatment.

• Correlates of Human Nerve Repair

  This is a longitudinal prospective cohort study in patients with carpal tunnel syndrome undergoing decompression surgery. Phenotypic data and skin biopsies were collected before and 6 months after surgery to determine molecular and cellular correlates associated with neural regeneration and neuropathic pain. RNA sequencing was performed in the skin samples and differential gene expression was determined post compared to pre surgery. The molecular changes identified in skin were correlated with the clinical phenotype representing neural regeneration.

• Extracellular microRNA Biomarkers for Diagnostic and Prognostic Assessment of Preeclampsia at Triage

  This study is comprised of samples from 123 donors (71 cases and 52 controls) undergoing evaluation for preeclampsia. All samples were collected between 20 and 40 weeks of gestation. Small RNA sequencing was done on serum RNA obtained from donors. We were able to identify 3 bivariate extracellular miRNA biomarkers that can enable early diagnosis of preeclampsia. The raw fastq small-RNA sequencing fastq files will be submitted to dbGaP.
