Additional file 1 of Rare predicted loss-of-function variants of type I IFN immunity genes are associated with life-threatening COVID-19

Additional file 1: Supplementary Methods. Fig S1. Luciferase assay on HEK293T cells transfected with the pGL4.32 luciferase reporter construct and an expression vector for Renilla luciferase together with no vector (mock), EV, WT, or 4 TLR7 variants found in our cohort. After 24 h, transfected cells were left untreated or were treated by incubation with 1 μg/mL R848 for 24 h. These data were established from two independent experiments. The y-axis represents NF-κB transcriptional activity as a percentage of the WT. The x-axis indicates the alleles used for transfection. Fig S2. Age distribution as boxplot and violin plot of the critical COVID-19 cases according to the carrier status of pLOF/bLOF at 15 type I IFN-related loci. Mean age of the patients for each category is shown in red. T-test was used to compare the means, showing a significant difference between non-carriers and carriers of heterozygous or homozygous/hemizygous variants (P = 2.2 × 10−6) and between heterozygous carriers and homozygous/hemizygous carriers (P = 0.008). Fig S3. Empirical power of our sample to detect an association at the 2.5 × 10−6 exome-wide significance threshold for various relative risks and proportion of carriers of at least one disease causing variant in the general population (PD), as estimated by simulation study (N = 1000 replicates).
