A study has shown that people with A blood group are more likely to have a stroke before the age of 60.
Blood types reflect different chemistry on the surface of our red blood cells.
The best known of these blood groups are A and B, which can be referred to together as AB. Individually they are identified as A or B and if they are not present, the blood is identified as O group.
Even in these major blood types, subtle changes occur due to variations in the genes within them.
In a study published in 2022, genomics researchers discovered a clear link between the A1 subgroup gene and early stroke risk.
In the latest study published in the journal Neurology, researchers pooled data from 48 genetic studies. About 17,000 people affected by stroke and about 600,000 people who were not affected were studied in this study. The age of all these people was between 18 to 59 years.
Genome-wide research has shown that there are two opportunities that are strongly associated with early stroke risk. One of them is where the genes that determine blood type are located.
Later, another analysis of specific variants of the blood type gene found that people whose genomes were coded for group A variants were more likely to suffer a stroke before age 60 than people with other blood types. I was 16 percent higher.
Participants who had the O1 gene had a 12 percent lower stroke risk.
