Researchers recommend population-wide screening for detecting mutation carriers — ScienceDaily

Tel Aviv University researchers suggest that carriers of the genetic mutations PiZ and PiS are at high risk for severe illness and even death from COVID-19. These mutations lead to deficiency in the alpha1-antitrypsin protein, which protects lung tissues from damage in case of severe infections. Other studies have already associated deficiency in this protein with inflammatory damage to lung function in other diseases.

The study was led by Prof. David Gurwitz, Prof. Noam Shomron, and MSc candidate Guy Shapira of TAU’s Sackler Faculty of Medicine, and published in The FASEB Journal on September 22, 2020.

The researchers analyzed data from 67 countries on all continents. Comparisons revealed a highly significant positive correlation between the prevalence of the two mutations in the population and COVID-19 mortality rates (adjusted to size of the population) in many countries, such as the USA, the UK, Belgium, Spain, Italy, and more.

Consequently, the researchers
