Relationship between the Prevalence of ACE1 I/D Polymorphism Genotype II and Covid-19 Morbidity, Mortality in Ukraine and in Some Europe Countries

Coronavirus disease (COVID-19), which was first recorded in China in December 2019, quickly spread to other countries and in a short period of time, the local outbreak escalated into a pandemic. There are significantly more cases of COVID-19 morbidity and mortality in European countries than in East Asia, where the disease was first detected. Such population differences are unique, especially for SARS-CoV-2 and are due to both socio-behavioral differences and features of the gene pool of the population of different countries. For infectious diseases, such as COVID-19, an important point is the genetic characteristics of individuals, which can determine its resistance or susceptibility to infection. Therefore, studies of the factors of hereditary predisposition to SARS-CoV-2 infection, as well as severity and mortality are extremely relevant. After genotyping among the healthy population of Ukraine and collecting relevant data from some European countries, we determined the correlation between morbidity, mortality from COVID-19 and the prevalence of genotype II (ACE1, I/D polymorphism) in the populations of Ukraine and several European countries. There was a negative correlation between the carrier of genotype II and susceptibility to SARS-CoV-2 infection per one million population (R = –0.53, p < 0.05), so individuals with genotype II can be considered more resistant to infection SARS-CoV-2. Further study of the role of allelic variants of the ACE1 gene in the development of severity and complications affected patients of COVID-19, are promising for identified of genetic markers for development of personalized therapy.
