Maternal mosaic sex chromosome aneuploidy detected by cfDNA screening has been described in the literature.1-2 Chimerism is a rare form of mosaicism where an individual has two distinct cell lines with different cellular origins; it may occur if one twin “absorbs” its other twin in utero.

Human Chimerism and mosaicism shows us that an individual can have a biological sex that is not binary, but exists on a spectrum. Different types of mosaicism exist, such as gonadal mosaicism (restricted to the gametes) or tissue mosaicism; one of them is chimerism , where two or more genotypes arise from the fusion of more than one fertilized zygote in the early stages of embryonal development. Visit our FAQ page! 0000013990 00000 n NOT TO BE CONFUSED WITH MOSAICISM Mosaicism is the presence of two or more related cell lines in an individual organism. Mosaicism originates by intrinsic genetic variations caused, among other processes, by somatic mutations, while chimerism originates from allogenic fusion or grafting.

Bone marrow cells also divide quickly, so when someone is undergoing chemo, their bone marrow cells are often seriously depleted.

The continuous harvesting of kelp along the Chilean coast is likely to reduce, fragment and isolate natural populations. As neither line could have derived from the other, chimerism and not mosaicism was suspected, with the 47,XY, + 9 cells deriving from a co‐twin whose demise was the result of the autosomal trisomy.

The pigmentary anomalies are pleomorphic, and the chromosomal anomalies involve autosomes and sex chromosomes. The literature contains at least 36 similar examples of an association between pigmentary anomalies and chromosomal mosaicism, as well as five examples of an association with chimerism.

Human Chimerism and mosaicism shows us that an individual can have a biological sex that is not binary, but exists on a spectrum. Different types of mosaicism exist, such as gonadal mosaicism (restricted to the gametes) or tissue mosaicism; one of them is chimerism , where two or more genotypes arise from the fusion of more than one fertilized zygote in the early stages of embryonal development. Visit our FAQ page! 0000013990 00000 n NOT TO BE CONFUSED WITH MOSAICISM Mosaicism is the presence of two or more related cell lines in an individual organism. Mosaicism originates by intrinsic genetic variations caused, among other processes, by somatic mutations, while chimerism originates from allogenic fusion or grafting.

Bone marrow cells also divide quickly, so when someone is undergoing chemo, their bone marrow cells are often seriously depleted.

The difference between them is that a genetic mosaic develops their second set of DNA later on in their life, while a genetic chimera is born with both sets of DNA. Laura Conlin, et al.
