Genotyping is the action of elucidating the genotype of an alone with a biological assay. Additionally accepted as a genotypic assay, techniques accommodate PCR, DNA fragment analysis, allele specific oligonucleotide (ASO) probes, DNA sequencing, and nucleic acerbic admixture to DNA microarrays or beads. Several accepted genotyping techniques accommodate brake fragment breadth polymorphism (RFLP), terminal brake fragment breadth polymorphism (t-RFLP),2 amplified fragment breadth polymorphism (AFLP),3 and circuitous ligation-dependent delving addition (MLPA).4
DNA fragment assay can additionally be acclimated to actuate such ache causing analysis aberrations as microsatellite alternation (MSI),5 trisomy6 or aneuploidy, and accident of heterozygosity (LOH).7 MSI and LOH in accurate accept been associated with blight corpuscle genotypes for colon, breast and cervical cancer.
The best accepted chromosomal aneuploidy is a trisomy of chromosome 21 which manifests itself as Down syndrome. Current abstruse limitations about acquiesce alone a atom of an individual’s genotype to be bent efficiently.
