Mosaicism describes an individual composed of two or more genetically different populations of cells existing side by side within the skin. CPM was first described by Kalousek and Dill in 1983. This syndrome can cause low amounts of testosterone. In rare cases, intersex conditions can be caused by mosaicism where some cells in the body have XX and others XY chromosomes. Mosaicism is a condition where an individual’s cells are genetically variegated. 45,X/46,XY mosaicism may be detected in individuals with nearly normal male external genitalia. 1974;3(0):33-45. In a normal cell, the concentrations of active (dephosphorylated) merlin are controlled by processes such as cell adhesion (which would indicate the need to restrain cell division). Some one of these chromosome imbalances … Artificial Mosaicism. Surender Rawat Down syndrome is a genetic disorder that results in an extra copy of chromosome 21. … Abstract.

The latter mechanism is more likely in the present cohort, since mosaicism at similar frequency was detected in several cell types. Typically, a person with only germline mosaicism will not be affected with the disorder caused by the mutation because the mutation is not in the other cells of the body. Mosaicism and Chimerism of Models . M. Sc. The last two are gaining more attention and I’ll try to do a post on micro-chimerism (small numbers of cells from different zygote) to explore in more detail. Sponsored Links.
