Method UK Biobank Axiom Array. Imputed SNPs used to perform a GWAS using super variants in statistical genetics to identify potential risk loci contributing to the COVID-19 mortality.
Bioinformatics Local ranking and aggregation used to identify super variants using a four step method which included two modes of transmission (recessive and dominant). This method was used in a discovery and validation identification. Logistic regression, replicated 10x for stability, was then used to investigate super variant associations with the death outcomes of COVID-19. Cox regression was used to futher validate supervariants verified in multiple runs.
Imputation details Haplotype Reference Consortium and UK10K and 1000 Genomes reference panels
Limitations Role of super variants in COVID-19 susceptibility not validated. Comorbidities were not accounted for in the association analysis eventhough UKB COVID-19 hospitalised patients had comorbidities. Study was restricted by sample size. Environmetal influencers not factored. No other ethnicities were included in this study.
