Genes, Blood Type Tied to Risk of Severe COVID-19
NIH Director's Blog, June 18, 2020 Brand
The analysis identified two places, one on chromosome 3 and covers a cluster of six genes with potentially relevant functions such as a protein known to interact with angiotensin converting enzyme 2 (ACE2). The other association signal popped up on chromosome 9, right over the area of the genome that determines ABO blood type.
We conducted a genomewide association study involving 1980 patients with Covid-19 and severe disease (defined as respiratory failure) at seven hospitals. We identified a 3p21.31 gene cluster as a genetic susceptibility locus in patients with Covid-19 with respiratory failure and confirmed a potential involvement of the ABO blood-group system.
COVID-19 and Blood Type: 'May Be Something Here'- Evidence is mounting that people with Type A blood could be at higher risk for COVID-19 infection and mortality, according to three recent studies. At the same time, Type O blood may be somewhat protective.
