• Inherited T Cell Defects: Diagnosis, Mechanisms and Treatments

  Infants with abnormal newborn screen results for severe combined immunodeficiency (SCID) and their parents were enrolled in UCSF IRB approved protocols with informed consent to have molecular and immunologic investigation to determine the cause of the infant's low T lymphocytes. Studies included exome sequencing of DNA from the infant and both parents. Candidate variants were investigated in mouse and zebrafish model organisms.

• Temporal and Clonal Progression in Pediatric Ependymoma

  Whole genome and exome-based DNA sequencing of germline and tumor specimens from serial samples of a single patient's ependymoma. The findings reveal the extent to which treatment with radiation and chemotherapies resulted in the diversification of the tumor subclonal architecture and shaped the neo-antigen landscape, and provide new insights into possible molecular mechanisms of oncogenesis, treatment response and recurrence.

• Rearrangements of the MAST Kinase and Notch Gene Families in Breast Cancer

  Paired-end transcriptome sequencing was performed on a panel of breast cancer cell lines and tissues and a set of benign cell line and tissue controls. Analyses of the paired end sequences were performed and chimeric transcripts derived from gene rearrangement events were identified. Sequencing was performed on Illumina GAII and HiSeq 2000 platforms with read lengths from 40 to 100 bases.

• Novel Gene-Environment Regulatory Circuit in Chamber-Specific Growth of Perinatal Heart

  We report a case of hypertrophic cardiomyopathy and lactic acidosis in a 3-year-old female. Cardiac and skeletal muscle biopsies exhibited mitochondrial hyperplasia with decreased complex VI activity. Whole exome sequencing identified compound heterozygous variants, p.Arg333Trp and p.Val119Leu, in TSFM, a nuclear gene that encodes a mitochondrial translation elongation factor, resulting in impaired oxidative phosphorylation and juvenile hypertrophic cardiomyopathy.

• Developmental Dynamics of Translation in the Human Brain

  We performed ribosome profiling and RNA sequencing from a total of 43 adult brain and 30 prenatal brain samples. The age of adult brain donors ranged from 18 to 82 years (average 39.5 years), with an average post-mortem interval of 9.9 hours. The gestational age of prenatal cortex samples ranged from 12 to 23 weeks, with a mean of 19.9 weeks.

• Investigating Human Placentation and Pregnancy Using First Trimester Chorionic Villi

  Chorionic villus sampling (CVS) is routinely used for prenatal diagnosis of cytogenetic disorders, but also possesses great potential for studying placentation. To better understand villi biology, human placentation, and how these relate to pregnancy outcomes, we examined the morphology and transcriptomes of villi obtained via CVS from 10-14 weeks of pregnancy and correlated these with pregnancy attributes and clinical outcomes.

• Relapsed Acute Lymphoblastic Leukemia (ALL): Mutational Landscape

  Multi-agent combination chemotherapy can be curative in acute lymphoblastic leukemia (ALL). Still, patients with primary refractory disease or those with relapsed leukemia have a very poor prognosis. Here we report the mutational landscape of matched diagnostic and relapsed pediatric and adult ALL samples. Our data provides comprehensive annotation of genetic lesions acquired at relapse and reveals diagnostic and relapse-specific mutational mechanisms in ALL.

• Nanopore cDNA Sequencing of Chronic Lymphocytic Leukemia

  While splicing changes caused by somatic mutations in SF3B1 are known, identifying full-length isoform changes may better elucidate the functional consequences of these mutations. We have performed nanopore sequencing of full-length cDNA from CLL samples with and without SF3B1 mutation, as well as normal B cell samples. With long reads, we analyzed alternative splicing patterns associated with SF3B1 mutation at an isoform-level.

• Single Cell Omics Resolves Transcriptional Alterations in Sjogren's Syndrome

  Single cell omics resolves transcriptional alterations in Sjogren's Syndrome. This data compares the single cell transcriptional profiles of the minor salivary glands between Sjogren’s Syndrome patients and non-Sjogren’s Syndrome subjects. Portions of this data were reported in two separate publications: Huang & Perez, et al., 2021 Nature Medicine and Yin, et al., 2021, Frontiers in Immunology .

• Inhibiting DNA Methylation Causes an Interferon Response in Cancer via dsRNA Including Endogenous Retroviruses

  We show that DNA methyltransferase inhibitors (DNMTis) upregulate immune signaling in cancer through the viral defense pathway and re-expression of epigenetically silenced endogenous retrovirus. In melanoma patients treated with an immune checkpoint therapy, high viral defense signature expression in tumors significantly associates with durable clinical response and DNMTi treatment sensitizes to anti-CTLA4 therapy in a pre-clinical melanoma model.
