<\/a>chimerism<\/p><\/div>\n
by Graham J. Noble<\/em><\/p>\n Thanks to a rare medical condition, a Washington state woman found out that pregnancy was not enough to prove motherhood; DNA testing indicated that she was, in fact, not the mother of her own children \u2013 so who was? During the course of a desperate battle to retain custody of her three children, it was discovered that her twin was the real biological parent. The twist? She, 26-year-old Lydia Fairchild, was her own twin.<\/p>\n By the time Fairchild was 23 years old, she had given birth to two children and was pregnant with a third. Her relationship with the father had been rocky. They separated \u2013 not for the first time \u2013 and she found herself, at 26, a struggling, single mother; out of work and unable to support her kids. When she applied for government assistance, however, her world was shattered by an incredible revelation \u2013 one that led to criminal accusations and the impending prospect of losing her children to the state.<\/p>\n In order to qualify for financial assistance in supporting her young family, Fairchild was required to undergo DNA testing to prove that she was the mother of children for whom she was claiming. Jamie Townsend, the father of all three children, was also required to submit to testing. Having twice been through pregnancy and childbirth and now in the middle of a third pregnancy, this test, Fairchild assumed, was merely a formality. It turned out not to be, however; In December, 2002, Fairchild was contacted by the Washington state prosecutor\u2019s office and told to come in to discuss the test results. To her horror, the young mother was informed that she would be the subject of an investigation into possible welfare fraud as the DNA tests had revealed no genetic link between her and the children she claimed were hers.<\/p>\n Lydia Fairchild<\/p><\/div>\n Townsend\u2019s biological link to the children had been confirmed, but the test came up with no evidence that Fairchild shared any DNA with the three children. She found herself being interrogated by Social Services; who was she? Who was the real mother of the children? Jamie Townsend was also questioned and accused of fathering the children with another woman. \u201cI knew that I carried them, and I knew that I delivered them. There was no doubt in my mind,\u201d Fairchild later recounted. Fairchild\u2019s obstetrician, Dr Leonard Dreisbach, was equally stunned by the accusation against the mother. \u201cI\u2019ve been doing this long enough to recognize when someone is giving birth right in front of you.\u201d he said.<\/p>\n The desperate mother soon found herself facing a summons and impeding legal battle to prove that she was the mother of the children to whom she had given birth and even to the one she now carried.<\/p>\n In another part of the country, another woman was facing a similarly bizarre situation; 52-year-old Karen Keegan, from Boston, Massachusetts, had discovered that DNA testing \u2013 carried out to find a genetic match in the search for a potential kidney donor \u2013 indicated no genetic link between her and two of her own three sons. After confirming a match between Keegan and her youngest son, her doctors sought further advice and were informed that Keegan might have a very rare genetic condition know as chimerism. Derived from the name of a strange hybrid creature, the Chimera of Greek legend, this condition had been documented just 30 times throughout the world. Those rare individuals, dubbed \u201cChimeras\u201d, had started out as twins; in the early stage of pregnancy, one of the twins had merged with \u2013 been absorbed by, one could almost say \u2013 the other twin.<\/p>\n The cells of the consumed twin, however, did not disappear and remained alive in one concentrated area of their sibling\u2019s body. In essence, a human chimera is one person made up of two separate sets f genetic material; they are, in fact, their own twins.<\/p>\n Baffled doctors conducted a number of tests on Karen Keegan but drew a blank; unable to find any genetic material in her body that matched that of her sons. Eventually, Keegan mentioned to her doctors that she once had a thyroid nodule removed. Determined to solve this medical mystery, the doctors tracked down material from the removed nodule to a medical lab in Boston. DNA extracted from the nodule matched that of her children.<\/p>\n Lydia Fairchild and Jamie Townsend\u2019s three children<\/p><\/div>\n Chimerism, however, was completely unknown to anyone dealing with Lydia Fairchild. Now in an advanced state of pregnancy, Fairchild found herself in court and about to lose custody of her children. The presiding judge ordered that blood samples be taken from her third child the moment Fairchild gave birth. Despite a court-appointed witness to the birth, tests on the blood samples, once again, showed no genetic link between the baby and its mother.<\/p>\n Fate, however, was on Lydia\u2019s side when one of the prosecutors in her case stumbled upon an article in the New England Journal of Medicine. That article had been written by Karen Keegan\u2019s doctors and chronicled the incredible discovery they had made. Further exploration of the mystery of Fairchild\u2019s DNA was ordered and a genetic link between her mother and her own children was confirmed. When Fairchild later had a cervical smear, DNA from it was tested and found to match that of her children. Fairchild\u2019s lost twin, it appeared, had lived on as cells only found in her ovaries; she was her own twin \u2013 and the twin was the biological mother of her children.<\/p>\n Some sixteen months later, after enduring the harrowing prospect of even pregnancy being no proof of motherhood, Lydia Fairchild found the case against her dismissed. Her attorney, Alan Tindell, reflected on the dire consequences of oversight in the testing of DNA. \u201cPeople go to death row because of DNA tests,\u201d he said, \u201cpeople are released from death row because of DNA tests.\u201d As for Karen Keegan and Lydia Fairchild \u2013 two women separated by thousands of miles but linked by a rare genetic condition \u2013 their separate, but bizarre tales, may well have inspired the medical community \u2013 and the justice system \u2013 to think again about the potential shortcomings of DNA testing.<\/p>\n","protected":false},"excerpt":{"rendered":" Pregnancy No Proof of Motherhood; Woman Was Her Own Twin-and the Twin Was the Mother of Her Children In an era of cloning, surrogate motherhood, turkey baster babies, and the potential for being ones own grandpa\/ma, the injustice of arrogant … Continue reading ![\"Lydia](\"http:\/\/amicuscuria.com\/wordpress\/wp-content\/uploads\/2014\/01\/Lydia-Fairchild.jpg\")
