SINGLE NUCLEOTIDE POLYMORPHISM Meaning and
Definition
-
Single nucleotide polymorphism (SNP) refers to a common type of genetic variation that occurs within a population at a single nucleotide position in the DNA sequence. Specifically, it denotes a variation in a single DNA building block, known as a nucleotide, which may vary among individuals within a species. SNPs can manifest as a substitution of one nucleotide with another, including transitions (purine to purine or pyrimidine to pyrimidine) or transversions (purine to pyrimidine or vice versa).
SNPs are valuable tools in genetic research as they have the potential to affect an individual's susceptibility to diseases, response to medications, and overall biological traits. These genetic variations can be located within genes or in the non-coding regions of the genome, and they can have different effects on an organism, from being benign to causing a significant impact on phenotypic traits.
The occurrence of SNPs is a result of natural genetic variations that arise due to errors in DNA replication, exposure to mutagenic agents, or recombination events. These variations can be inherited by offspring, leading to a diverse genetic composition within a population. Due to the abundant occurrence of SNPs in the human genome, they have become the focus of numerous studies aiming to unravel their relationship with diseases and phenotypic traits.
Through statistical analyses and genome-wide association studies (GWAS), scientists can identify SNPs associated with particular conditions or traits, providing valuable insights into the underlying genetic factors contributing to complex human diseases and individual differences.
