Brief summary
Background: Coronavirus 2019 (COVID-19, or SARS-CoV-2) is a serious public health problem, and genetics may play a role in how serious the illness becomes in certain people. Genes are the instructions that our body uses to grow and develop. Variations in our genes can cause medical conditions and may be the reason why some people get sicker than others. Objective: This study aims to learn more about the genetic contributions to the severity of COVID-19. We hope to use this information to develop therapies that reduce the severity of COVID-19 symptoms in some people. Eligibility: Anyone located in the United States who has tested positive for SARS-CoV-2 infection may be eligible to join (including NIH staff). Design: Participants will complete a questionnaire about their health history and COVID-19 symptoms. Participants will give a blood or saliva sample. It will be about 2 tablespoons of blood, or we will send a saliva collection kit. Researchers will use this blood or saliva sample to study the participant s DNA. The data about participants genes will be stored in a large database. The database will be shared with other qualified researchers who are trying to learn about COVID-19. Participants names and other personal details will not be shared. Instead, the data will be labeled with a code. Participants may be contacted by study team members for up to a year after they join the study.
Detailed description
The current SARS-CoV-2 pandemic presents a serious challenge to public health. Individuals infected with SARS-CoV-2 experience extremes in symptomatology ranging from a complete lack of symptoms to rapidly worsening end-stage pulmonary disease. The explanatory mechanism underlying susceptibility to severe disease remains unknown. We hypothesize that underlying genetic factors are at least partially explanatory. We aim to employ a phenotypic extremes approach to rapidly ascertain severely and mildly affected COVID-19 patients for genomic interrogation to identify germline and somatic variants that may play a role in host susceptibility to disease to correlate those phenotypic extremes with genetic variants. We will employ both a rare and common variant approach, using both genome sequencing and SNP chip analysis and B and T cell repertoire interrogation.
