Long-term COVID-19 symptoms
Here, Helix researchers make use of the Helix research community—consisting of people from many different cultures, socioeconomic backgrounds, and varying exposure to SARS-CoV-2—to assess the enduring nature of COVID-19.Helix Research
Innate immune signaling, inborn errors, and COVID-19 severity
In two studies recently published in Science Magazine, an international team of researchers—including multiple Helix scientists—make a strong case that type 1 interferons (IFNs) are essential to control SARS-CoV-2; that diminished IFN response is a cause of severe symptoms; and that auto-antibodies to cytokines can lead to immunodeficiencies.

Prevalence of exonic CNVs in ACMG 59 genes
Unlike SNVs and indels, CNVs are not always reported as part of a healthy population screen or secondary findings analysis. Here, we present evidence that they should be, as 0.4% of the ~30,000 healthy individuals enrolled in the Healthy Nevada Project (HNP) were found to have CNV variants in ACMG 59 genes—showcasing the potential clinical impact of adding a CNV analysis to a screening program.

Early onset of disease in individuals with a monogenic risk compared to individuals with high polygenic risk
How does the age of onset of disease for individuals with a high polygenic risk for breast cancer, colorectal cancer, or hypercholesterolemia compare to the age of onset of disease for individuals with monogenic risk—carrying a pathogenic variant—for these conditions? Here, we dive into this question using data from the Healthy Nevada Project cohort, including EHR and Exome+ for 40,000 unselected adults.

Scalable return of results for large scale population genomics programs
GWAS and COVID-19 severity
Data from the Exome+ assay as well as an ongoing phenotypic survey of research consented participants is contributing to studies done through the Host Genetics Initiative. One recent study leveraged this data to support the finding of an association between a specific gene cluster and COVID-19 severity.
