There is a critical difference between deletion and CN-LOH, as the latter mechanism cannot be detected by comparative genomic hybridization (CGH)-based gene copy number counting, and requires allelic genotyping. Either way, LOH leaves only non-functioning alleles of the TSG, and the individual may go on to … See more Loss of heterozygosity (LOH) is a type of genetic abnormality in diploid organisms in which one copy of an entire gene and its surrounding chromosomal region are lost. Since diploid cells have two copies of their genes, one from … See more Loss of heterozygosity can be identified in cancers by noting the presence of heterozygosity at a genetic locus in an organism's germline DNA, and the absence of heterozygosity at … See more • Inbreeding depression • Microsatellite instability • Tumor suppressor gene • Virtual Karyotype See more The loss of heterozygosity is a common occurrence in cancer development. Originally, a heterozygous state is required and indicates the absence of a functional tumor suppressor gene copy in the region of interest. However, many people remain healthy with such a … See more It has been proposed that LOH may limit the longevity of asexual organisms.
