Because the differences are quite small, an extremely large sample size is needed to explore differences across groups. Comparing Blood TypesĢ3andMe researchers wanted to investigate this link with blood type, so we estimated the contribution to risk by comparing each blood group against each of the others. The preliminary findings from 23andMe’s data are also notable because of the link between COVID-19 blood clotting, and cardiovascular disease. This is because it serves as receptors, or coreceptors for microorganisms, parasites, and viruses. We know from other studies that the ABO blood group can play a direct role in other types of infections. Numerous other studies have reported that the ABO blood group plays a role in both susceptibility and severity for COVID-19 (refs: 1, 2, 3). The study in China looked at susceptibility, while the Italian and Spanish study found an association with blood type and severity of the illness. The P-value for the association is 1.4e-8, OR = 0.88).īoth the data on blood type and the preliminary genetic findings also appear to support at least two recently published pre-print studies - one by researchers in China and the most recent one by researchers in Italy and Spain - that look at the ABO gene’s role in COVID-19. (The single nucleotide polymorphism in the ABO gene is rs505922, a T at that location is associated with lower risk. Our researchers identified a variant in the ABO gene associated with a lower risk. We’ve compared the research participants who reported that they tested positive for COVID-19 to those who tested negative. While it is still very early in the study, 23andMe’s preliminary investigation into genetics seems to support these findings.

Among those exposed to the virus - healthcare and other front line workers - 23andMe found that blood type O is similarly protective, but the proportion of cases within strata is higher.Nor was this a factor in susceptibility or severity in cases.

Although one study found the blood group O only to be protective across rhesus positive blood types, differences in rhesus factor (blood type + or -) were not significant in 23andMe data.These findings hold when adjusted for age, sex, body mass index, ethnicity, and co-morbidities.There appeared to be little differences in susceptibility among the other blood types.Individuals with O blood type are between 9-18% percent less likely than individuals with other blood types to have tested positive for COVID-19, according to the data.The preliminary data suggest that O blood type appears to be protective against the virus when compared to all other blood types.A First Lookīut a first blush look at the information from the more than 750,000 participants in the study shows the following: are eligible to participate in this study.) 23andMe researchers have yet to finish looking at what the genetic data indicate. ( Note: Currently, only those living in the U.S. Compare our DNA tests to learn more about our services.Ģ3andMe is still recruiting for its massive study, most recently seeking 10,000 participants outside of 23andMe who have been hospitalized and diagnosed with COVID-19.

While 23andMe researchers continue to explore the implications of this data, we’re also continuing to provide important genetic health information to our customers. Preliminary data from 23andMe’s ongoing genetic study of COVID-19 appears to lend more evidence for the importance of a person’s blood type - determined by the ABO gene - in differences in the susceptibility to the virus. See the findings from our COVID-19 Study here. Please note, 23andMe does not currently offer a report on blood type, and our COVID-19 research is now complete. Editor’s note 9/5/23: Thanks to all our readers for their questions on this post.
