Host methylation predicts SARS-CoV-2 infection and clinical outcome.

ABSTRACT:

Background

Since the onset of the SARS-CoV-2 pandemic, most clinical testing has focused on RT-PCR¹. Host epigenome manipulation post coronavirus infection^2-4 suggests that DNA methylation signatures may differentiate patients with SARS-CoV-2 infection from uninfected individuals, and help predict COVID-19 disease severity, even at initial presentation.

Methods

We customized Illumina's Infinium MethylationEPIC array to enhance immune response detection and profiled peripheral blood samples from 164 COVID-19 patients with longitudinal measurements of disease severity and 296 patient controls.

Results

Epigenome-wide association analysis revealed 13,033 genome-wide significant methylation sites for case-vs-control status. Genes and pathways involved
