An SNP array is a useful tool for studying slight variations between whole genomes. The most important clinical applications of SNP arrays are for determining disease susceptibility [5] and for measuring the efficacy of drug therapies designed specifically for individuals. [6] In research, SNP arrays are most frequently used for genome-wide ...

SNP genotyping is the measurement of genetic variations of single nucleotide polymorphisms (SNPs) between members of a species. It is a form of genotyping, which is the measurement of more general genetic variation. SNPs are one of the most common types of genetic variation.
Data analysis for an array-based DNA copy number test can be very challenging though due to very high volume of data that come out of an array platform. BAC (Bacterial Artificial Chromosome) arrays were historically the first microarray platform to be used for DNA copy number analysis. This platform is used to identify gross deletions or ...
Technically the term SNP only refers to these kinds of variations, however in practice they are often used synonymously with SNV in the literature on variant calling. In addition, since the detection of germline SNVs requires determining the individual's genotype at each locus, the phrase "SNP genotyping" may also be used to refer to this process.
SNP-based arrays are preferred for virtual karyotyping of tumors and can be performed on fresh or paraffin-embedded tissues.

These types of arrays can help reduce the cost of identifying risk factors, since they allow researchers to screen for ancestry markers instead of the entire genome. This is due to the fact that these SNP arrays narrow the scope of the necessary screening from hundreds of thousands of SNP markers to a panel of a few thousands of AIMs.
SNPs are the most common genetic variant found in all individual with one SNP every 100–300 bp in some species. [4] Since there is a massive number of SNPs on the genome, there is a clear need to prioritize SNPs according to their potential effect in order to expedite genotyping and analysis. [5]
