5. CONCLUSIONS
We
conclude that the prevalence distribution of the risky alleles of the
gene defect that causes A1AT insufficiency, which is one of the most
important protective factors of lung tissue, is related to the
prevalence of COVID-19 pandemic data. More detailed studies are needed
on the relationship between A1AT and COVID-19 in order to confirm this
argument, which we think can contribute significantly to combating the
COVID-19 pandemic.
Limitations: Restriction of the source articles concerning A1AT
data should be considered as our limitations.
