CardioSURE is based on testing genetic markers called Single Nucleotide Polymorphisms commonly known as SNPs. A SNP is basically a change in our DNA code. These genetic markers are present in our DNA when we are born.
Most SNPs are harmless, but sometimes SNPs can occur in important functional regions of our DNA. Such SNPs can cause disease or be associated with an increase risk of developing a disease.
SNPs linked to an increased risk of heart disease were identified in a study carried out by researchers in Canada and Finland. This was published in the prestigious PLoS Medicine Journal in 2011**. The study was the largest ever carried out and was done on 19,129 people from Europe, Asia, China, Arab and South American population groups.
