A SNP array can also be used to generate a virtual karyotype using software to determine the copy number of each SNP on the array and then align the SNPs in chromosomal order. [10] SNPs can also be used to study genetic abnormalities in cancer. For example, SNP arrays can be used to study loss of heterozygosity (LOH). LOH occurs when one allele ...
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.
In order to perform SNP genotyping, Hardenbol et al. [3] modified padlock probes such that when the probe is hybridized to the genomic target, there is a gap at the SNP position. Gap filling using a nucleotide that is complementary to the nucleotide at the SNP location determines the identity of the polymorphism.

SVM based system to find genes using heterogeneous information: RNA-seq, tiling arrays: Eukaryotes [35] MORGAN: Decision tree system to find genes in vertebrate DNA: Eukaryotes [36] BioNIX: Web tool to combine results from different programs: GRAIL, FEX, HEXON, MZEF, GENEMARK, GENEFINDER, FGENE, BLAST, POLYAH, REPEATMASKER, TRNASCAN ...
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 ...
Single nucleotide polymorphism annotation (SNP annotation) is the process of predicting the effect or function of an individual SNP using SNP annotation tools. In SNP annotation the biological information is extracted, collected and displayed in a clear form amenable to query.
In the field of genetic sequencing, genotyping by sequencing, also called GBS, is a method to discover single nucleotide polymorphisms (SNP) in order to perform genotyping studies, such as genome-wide association studies . [1] GBS uses restriction enzymes to reduce genome complexity and genotype multiple DNA samples. [2]
