Reference SNP cluster ID (rsID)

An Reference SNP cluster ID, commonly called an rsID, is a unique identifier assigned to a specific change in the DNA sequence known as a single nucleotide polymorphism (SNP). SNPs are tiny variations in our genetic code that can influence traits and health. The rsID helps scientists and researchers universally identify and study these genetic differences across different studies and databases. For example, rs123456 might refer to a specific variation in a gene linked to a health trait. This standard naming system helps organize and share genetic information efficiently.
