SNPs (Single Nucleotide Polymorphisms)

Single Nucleotide Polymorphisms (SNPs) are tiny variations in our DNA, specifically where a single building block (nucleotide) differs among individuals. Imagine DNA as a long string of letters; if one letter changes in a specific spot, that’s a SNP. These variations can affect how we look, how our bodies respond to diseases, and how we react to medications. SNPs are important in genetics and medicine because they help researchers understand genetic diversity and the factors influencing health and disease in different populations.

    Single nucleotide polymorphisms (SNPs) are the most common type of genetic variation among people. They occur when a single building block (nucleotide) of DNA is changed, such as switching an 'A' for a 'C'. These tiny differences can influence how we look, how our bodies function, and even our risk for certain diseases. While most SNPs do not affect health or development, some can play a significant role in how individuals respond to medications or their susceptibility to illnesses. SNPs are valuable in genetic research, helping scientists understand complex traits and personalized medicine.
