Preliminary study: nutrigenomics analysis results of COVID-19 survivors

Numerous attempts have been made at both prevention and treatment of COVID-19. Specific genotypes carry a risk of causing clinical symptoms that can be beneficial or detrimental. We performed nutrigenomics testing on COVID-19 survivors who were on ventilators during their treatment and mild COVID-19 survivors who did not require ventilators to determine the risk of genetic variation through nutrigenomic testing regarding COVID-19 incidence. DNA was isolated from saliva and genotyped for genetic markers using a commercially available nutrigenomics test. We compared genotype frequencies between those with severe symptoms (cases) and those with mild symptoms (controls). Sequencing results showed that the distribution from pattern of the Sankey diagram included an ultra risk category in the control group, but not in the case group. None of the subjects in the case group were in the ultra risk category for resilience. A descriptive pattern of risk-level distribution was observed in both the control and case groups. One subject in the ultra risk category was in the control group, indicating a lower risk factor for severe COVID-19. From this study, a uniqueness begins to emerge, revealing the discovery of ultra-category patterns in the endurance of the control group. The vitamin E risk deficiency is significantly higher in the severe COVID-19 group compared to the mild group, categorized as "typical."
