Definitions for "LOH"
OH-6 Light Observation Helicopter. Sometimes written as Loach. It was small, maneuverable and carried two pilots and three passengers.

In 1960, the Department of Defense (DoD) requested proposals for the LOH program, a small, maneuverable, personnel transport, cargo, MedEvac, light ground attack, artillery, and photo reconnaissance helicopter. The LOH program was won by the Hughes OH-6A Cayuse.
Loss Of Hire.
(Loss of Heterozygosity) Very large deletion or chromosomal loss (non-matched recombination event) results in hemizygote
The loss of a portion of a chromosome in somatic cells. Since only one of the two copies of the affected chromosomal region originally present in an individual's genome will remain in cells which have undergone LOH, all polymorphic markers within the region will appear to be homozygous; i.e. these cells will have lost heterozygosity for these markers. Comparison of marker genotypes in a population of cells that are suspected of having undergone LOH with genotypes of normal tissue from the same individual allows for the identification of LOH, and for mapping the extent of the loss. LOH is frequently seen in cancer calls, where it is thought to contribute to the process of tumorigenesis due to the loss of tumor suppressor genes.
