Genetics
Detecting SNPs in Human DNA
Description
SNPs, or single nucleotide polymorphisms, are the most common form of genetic variation in humans. They are changes at a single DNA base. In many cases, these differences do not directly affect gene expression. Even so, they can help scientists locate disease-associated genes or support patient diagnosis.

Transcript
Genetic variation occurs both within and between different populations, and it contributes to the variation in traits, including disease susceptibility, among individuals. The most common variations are single nucleotide polymorphisms, or SNPs. SNP genotyping involves determining the specific sets of variants, in this case SNP...
