• Genomic analysis Nasopharyngeal cancer through whole exome sequencing and whole genomic sequencing.

  Nasopharyngeal carcinoma (NPC) is a squamous-cell carcinoma and has remarkable ethnic and geographic distribution, with a high prevalence in southern China, southeast Asia, northern Africa and Alaska. Although there are previous studies implicated NF-κB pathway play an important role in NPC. Newer research also found several important cellular processes and pathways in NPC, including chromatin modification, ERBB-PI3K signaling and autophagy machinery. Put these studies together, although, NPC is still poorly understood at the genetic level. Here we determined the mutational landscape of 553 cases with NPC using whole-genomic and whole-exome sequencing. These approaches revealed a distinct mutational signature and significantly mutated genes.

• Hepatitis B virus integrations promote local and distant oncogenic driver alterations in hepatocarcinogenesis

  Infection by Hepatitis B Virus (HBV) is the main risk factor for Hepatocellular Carcinoma (HCC) worldwide. HBV can directly drive carcinogenesis through integrations in human genome. This integrative analysis of a French cohort of 190 patients mainly coming from Europe and Africa provides a deep characterization of HBV integrations, in relation with viral and host genomics and clinical features. Clonal HBV integrations directly contribute to HCC development through alterations of cancer driver genes, either at distance when co-localizing with copy number alterations, either locally through viral Enhancers. Together, this analysis gives new insights on HBV-associated driver mechanisms involved in hepato-carcinogenesis.

• Ethiopia Genome Project (low coverage)

  The Ethiopian area stands among the most ancient ones ever occupied by human populations and their ancestors. Particularly, according to archaeological evidences, it is possible to trace back the presence of Hominids up to at least 3 million years ago. Furthermore, the present day human populations show a great cultural, linguistic and historic diversity which makes them essential candidate to investigate a considerable part of the African variability. Following the typing of 300 Ethiopian samples on Illumina Omni 1M (see Human Variability in Ethiopia project, previously approved by the Genotyping committee) we now have a clearer idea on which populations living in the area include the most of the diversity.This project therefore aims to sequence the whole genome of 300 individuals at low (4-8x) depth belonging to the six most representative populations of the Ethiopian area to produce a unique catalogue of variants peculiar of the North East Africa. Furthermore 6 samples (one from each population) will also be sequenced at high (30x) depth to ensure full coverage of the diversity spectrum.The retrieved variants will be of great help in evaluating the demographic dynamics of those populations as well as shedding light on the migrations out of Africa.

• Nature and Contribution of Noncoding, Regulatory Mutations in Neurodevelopmental Disorders

  This dbGaP study contains variant call files generated from whole-genome sequencing data of families with autism. The variant callers include FreeBayes, GATK, Platypus, and Strelka2. A family-level VCF file, from each caller, is provided for each family in the study. The families included in this study are from the Simons Simplex Collection (SSC), the Study of Autism Genetics Exploration (SAGE), and The Autism Simplex Collection (TASC); sequencing was performed at the New York Genome Center, as part of the Centers for Common Disease Genomics (CCDG) Consortium. The analysis to generate the variant callsets was supported by a K99 Pathway to Independence grant to Dr. Tychele Turner (1K99MH117165-01). *Access to phenotype data at the individual level for Simons Simplex Collection (SSC) subjects can be requested from SFARI Base: https://www.sfari.org/resource/sfari-base/.

• Rapid Acceleration of Diagnostics - Digital Health Technologies (RADx-DHT): NIH Digital Health Solutions for COVID-19: IBM Covid19 Contact Tracing and Data Exchange Tools

  The goal of this project is to develop both contact tracing and secure data exchange tools. The contact tracing solution securely combines data from a variety of sources (including manual self-report data and mobile device surveys) to enable tracing of contacts with individuals that have tested positive for COVID-19 or have been exposed to COVID-19. The data exchange solution is a secure mechanism that empowers users to control the data they share in the course of their return to work, including the ability to provide a verifiable health status claim. These tools are being used by an employer to evaluate the risk of allowing individuals to return to normal activities, and also the ability to trace user contact with individuals diagnosed with or suspected of having contracted COVID-19.

• Rapid Acceleration of Diagnostics - Digital Health Technologies (RADx-DHT): Covidseeker and COVID-19 Citizen Science: Leveraging Citizen Science and Real-Time Geospatial Temporal Mobile Data for Digital Contact Tracing and SARS-CoV-2 Hotspotting

  The Covidseeker and COVID-19 Citizen Science Study integrates a retrospectively-determined geolocation digital program into an established digital infrastructure housed within the NIH-funded Eureka platform to enroll SARS-CoV-2 positive and negative individuals. The solution also leverages the ongoing COVID-19 Citizen Science Study cohort both in-person and remotely to test and implement existing technology to enhance readily accessible contact tracing methods and identify “hot spots” of transmission of SARS-CoV-2. The tools are designed to alert users regarding overlap with SARS-CoV-2 infected individuals, identifying businesses that were visited by someone who later tested positive for COVID-19, and working with those businesses and public health departments on strategies to reduce the spread of the virus.

• RODAM

  The RODAM study assesses the health and wellbeing of Ghanaian residents in Ghana and Europe and follows them up over time. With this unique approach the RODAM study attempts to unravel the causes of cardiovascular disease and its risk factors among African migrants in Europe and non-migrants sub-Saharan Africa. Data are available upon reasonable request. These requests can be made to de RODAM-Pros cohort coordinator (rodamcoordinator@amsterdamumc.nl) or principal investigator, Professor Charles Agyemang (c.o.agyemang@amsterdamumc.nl).
