MSH: The loss of one allele at a specific locus, caused by a deletion mutation; or loss of a chromosome from a chromosome pair, resulting in abnormal HEMIZYGOSITY. It is detected when heterozygous markers for a locus appear monomorphic because one of the ALLELES was deleted.,CSP: genetic phenomenon due to deletion or mutation in one allele of a polymorphic gene, as detected by expression after cell fusion; used as a test for tumor-promoting mutations; do not confuse with "loss of heterogeneity" which applies to diverse cell populations within a tissue.,CHV: a kind of genetic abnormality associated with cancer,CHV: a kind of genetic abnormality associated with cancer,CHV: a kind of genetic abnormality associated with cancer,NCI: If there is one normal and one abnormal allele at a particular locus, as might be seen in an inherited autosomal dominant cancer susceptibility disorder, loss of the normal allele produces a locus with no normal function. When the loss of heterozygosity involves the normal allele, it c
