dbSNP

dbSNP, or the Database of Single Nucleotide Polymorphisms, is a freely accessible database that catalogues variations in DNA sequences across different individuals. These variations, known as SNPs, often involve a change in a single DNA building block (nucleotide) and can influence traits, disease risk, and response to medications. Researchers and healthcare professionals use dbSNP to study genetic diversity, understand the genetic basis of diseases, and improve personalized medicine. By providing a comprehensive resource of genetic variations, dbSNP plays a crucial role in advancing genomics and biomedical research.
