Heterozygous refers to having inherited different forms of a particular gene from each parent.

. Loss of heterozygosity LOH in cancer frequently results from copy number alterations CNAs that can alter dozens to thousands of genes in cancer genomes 910. Forty-two percent of the 101 cancer cases analysed were found to possess alterations of the microsatellites manifesting with allelic loss. In practice therefore pure loss of an allele is rarely seen in LOH studies because of the contaminating normal tissue and studies rely on equating allelic loss to allelic imbalance.
