Genome-wide SNP arrays

Genome-wide SNP arrays are laboratory tools used to analyze many small genetic variations called single nucleotide polymorphisms (SNPs) across a person’s entire genome. These variations can help identify genetic predispositions to diseases, traits, or responses to medications. The process involves extracting DNA, applying it to a specialized chip with known genetic markers, and then using technology to detect which variants are present. This approach allows researchers and clinicians to quickly and cost-effectively examine numerous genetic differences simultaneously, providing valuable insights into an individual’s genetic makeup.
