It divides into two, making copies of these chromosomes, and we think that every cell down the line ends up with the same genetic bundle. A bone marrow transplant which comes from an outside donor (often used in cases of blood cancer) will also create chimerism, as the bone marrow is the birthing and nurturing ground for blood cells. We concluded that the patient is a parthenogenetic chimera, which is composed of two paternal alleles and one duplicated maternal allele (Fig. This United States biographical article is a stub. All microsatellite markers showed a single maternal allele. Whereas tetragametic chimeras are known as the most common subtype of XX/XY chimeras, which are derived from the simple fusion of two different zygotes, parthenogenetic chimeras and androgenetic chimeras [8, 11] undergo endoreplication of one of the gametic genomes.

To confirm chimerism, we carried out SNP microarray analysis using a CytoScan 750K Array (Affymetrix, Santa Clara, CA). Two weeks later, DNA tests seemed to indicate that she was also not the mother of that child.

As in Keegan's case, DNA samples were taken from members of the extended family. David Madden $430,400 To investigate the parental origin of the genome in the patient, we performed microsatellite marker analysis, as known as short tandem repeat (STR) analysis. Following evidence from another case of chimerism documented in The New England Journal of Medicine in a woman named Karen Keegan, Fairchild was able to secure legal counsel and establish evidence of her biological maternity. Chimera resulting from the fusion of XX- and XY-embryos are the most likely to be discovered because mixed gonads can result in abnormalities of the external genitalia. However, once they took a sample from Fairchilds cervix, the narrow tube that connects the vagina to the uterus, they finally found a second DNA lineage that matched those of her children. Transfusion 45:698703, Yu N, Krushall MS, Yunis JJ et al (2002) Disputed maternity leading to identification of tetragametic chimerism.
