Specifically, rare variants were predicted to be loss-of-function (LOF) at 13 human loci known to govern TLR3- and IRF7-dependent type I interferon (IFN) immunity to influenza virus in patients with life-threatening COVID-19 pneumonia, relative to subjects with asymptomatic or benign infection. These genetic defects display incomplete penetrance for influenza respiratory distress and only manifested clinically upon infection with the more virulent SARS-CoV-2. </p> <h2>Display Conventions</h2> +<p> +Unlike a regular genome browser track, the <b>COVID-19 Immunity Variants</b> track displays all +affected genes in <a href="https://genome.ucsc.edu/goldenPath/help/multiRegionHelp.html">multi-region view</a>, +showing the variants within the coordinates of the gene, but hiding all the intergenic bases.

The proportion of individuals carrying at least one pLOF variant was compared between cases and controls by means of logistic regression with the likelihood ratio test. The first three principal components of the PCA were included in the logistic regression model to account for ethnic heterogeneity of the cohorts. Analysis of enrichment in rare (MAF < 0.001) synonymous variants of the 12 genes was performed to check the calibration of the burden test. PCA was conducted with Plink v1.9 software on whole exome and genome sequencing data and 1000 Genomes (1kG) Project phase 3 public database as reference, using 27,480 exonic variants with a minor allele frequency >0.01 and a call rate >0.99. The odds ratio was also estimated by logistic regression and adjusted for ethnic heterogeneity. @@ -54,17 +67,16 @@ particular to Qian Zhang at the Rockefeller University for review and input during browser track development. </p> <h2>References</h2> <p> Zhang Q, Bastard P, Liu Z, Le Pen J, Moncada-Velez M, Chen J, Ogishi M, Sabli IKD, Hodeib S, Korol C <em>et al</em>. <a href="https://www.ncbi.nlm.nih.gov/pubmed/32972995" target="_blank"> Inborn errors of type I IFN immunity in patients with life-threatening COVID-19</a>. <em>Science</em>. 2020 Sep 24;.
