Do you know your individual genetic SNIPS? If not, read on to learn more about how these can affect your health!
Genetic testing seems to be all the rage right now! If you have heard anyone talk about their “SNIPS” is casual conversation, here is some more context to what that actually means…
1. Single Nucleotide Polymorphisms means one base is substituted for another in the DNA sequence.
2. For example, this pattern should be replicated exactly the same, but now one base is substituted for another. Do you see it below?
3. ( A-A-G-C-T-G) is now (A-T-G-C-T-G).
4. What effect does this have?
5. SNPs occur normally throughout a person’s DNA.
6. They occur almost once in every 1,000 nucleotides on average, which means there are roughly 4 to 5 million SNPs in a person’s genome.
7. These variations may be unique or occur in many individuals; scientists have found more than 100 million SNPs in populations around the world.
8. Most commonly, these variations are found in the DNA between genes. They can act as biological markers, helping scientists locate genes that are associated with disease.
9. When SNPs occur within a gene or in a regulatory region near a gene, they may play a more direct role in disease by affecting the gene’s function.
