Abstract: There is strong individual variability in both susceptibility and clinical response to covid-19 infection. People with chronic obstructive pulmonary disease (COPD) constitute one of covid-19 risk groups for poor outcomes upon infection. This study contributes to unveil the underlying reasons for such outcomes by looking at the genetic background of people with COPD. 255 people with COPD (66±9y; 72%♂; FEV1 53.01±20.31pp) and 243 controls (67±10y; 80%♂; FEV1 100.46±19.19pp) were clinically characterized and genotyped using saliva samples. Covid-19 associated SNPs from the literature (susceptibility: rs286914/rs12329760; severity: rs657152/rs11385942) were assessed and their allelic frequencies used to calculate the probability of having multiple risk alleles in both groups. Polygenic risk analysis was also conducted. No differences in genetic risk for covid-19 susceptibility or severity were found between groups (all p-values > 0.01), either considering individual risk alleles, allelic combinations or polygenic risk scores (Fig. 1). These results suggest a low genetic contribution for the poor covid-19 outcomes observed in people with COPD.
