    The ongoing pandemic caused by severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2, COVID-19) has an estimated overall case fatality ratio of 1.38% in China, being 53% higher in males TRANS and increasing exponentially with age TRANS. Mosaicism for X chromosome monosomy MESHD (XCM) shows a similar increase in aging population mostly driven by loss of chromosome Y in males TRANS (LOY), and is associated with a raise in all-cause mortality. Using comparative transcriptomic data, we have defined that XCM/LOY is associated with abnormal peripheral blood SERO cell counts with decreased progenitor cells and multiple biomarkers of immune system dysfunction, pro-coagulation activity and increased cardiovascular risk. Several differentially down-regulated genes in XCM/LOY individuals are involved in the initial immune response to SARS-CoV-2 (OR of enrichment=7.23, p=1.5x10-7), mainly interferon-induced genes that code for inhibitors of viral processes. Thus, our data suggest that XCM mosaicism underlies at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential relevance for modulating prognosis and therapeutic response, we propose that evaluation of LOY and XCM by currently established methods should be implemented as biomarkers in infected patients, including currently ongoing clinical trials with different medications and vaccines for COVID-19. Testing for LOY/XCM at large scale among elderly TRANS people may also be helpful to identify still unexposed people who may be especially vulnerable to severe Covid-19 disease MESHD.
