Strangely, the baby does not have mother's DNA

The Iliad depicts the monster Chimera with a snake's tail, a goat, a lion's head; Chimera also became the name for a genetic phenomenon called genetic chimerism or tetragametism. In DNA tests to determine parents' offspring, a Chimerism case was discovered when the child was not biologically connected to the mother - it carried another DNA. The young mother in Washington state struggled with the court to keep the baby she was carrying heavily because it was not her biological child.

'Who are you? What are you plotting with the kids? '

Lydia Fairchild, 26, gave birth 3 times. After the third child was born, she was unemployed. Due to inadequate economic conditions for raising three children alone, Lydia must write a monthly government grant application at the local residence, Washington state. Everyone in her family was summoned to the Department of Social Services to prove some relevant information. At first, Fairchild thought it was simply a summoning as usual with a social worker. But she did not expect a strict questioning like a criminal suspect. She was dead when the court announced her boyfriend was the father of the children. And she, who gave birth to them, is not her mother, because her DNA does not coincide with them.

Lydia Fairchild will remember that day forever. The court staff called out to her suspiciously: 'Who are you? What are you plotting with the kids? ' Surprised, Lydia answered, " They are my children, why is there a plot here?". The person replied coldly: 'They are not your children. We tested DNA. Her DNA and the children are not the same '. From the court back, Lydia seemed to be going crazy. Apparently she was the mother of three children. She was pregnant and gave birth normally. All family members, neighbors and doctors at the maternity home know. Even the father's DNA samples are consistent with the DNA of the three children. But all those are meaningless in court. Medical theory has confirmed that mother and child DNA must be similar. 100% of cases are like that. The opposite can only be fake.

Sister Lydia Fairchild

Doubting that the trial of the court was flawed, Lydia asked for a repeat of it in some independent laboratories of her own choosing. The results are still the same, there are no errors. She - who gave birth to them is not her mother. Although all three children insisted that their mother was Lydia Fairchild - the person standing in front of them. However, that is not a convincing evidence. Thus, from just wanting to apply for a monthly social allowance to raise children, Lydia faces the risk of committing crimes: She could be accused of falsifying and abusing children, even kidnapping children. you In that case, the children will be taken to the social protection center and Lydia will never see her children again.'You know that. We can pick up the kids at any time , 'a social worker told Lydia before she left the room.

There is confusion?

After long, skeptical 'interrogations' , Lydia started to panic, she staggered. Lydia hurried back home to find ultrasound pictures during her pregnancy of each child. While trying to search, Lydia told her parents about the result of that 'weird' DNA test. Lydia's parents did not believe. 'At first, I thought, she was joking. There must be some confusion! I was the one who took Lydia to the hospital. Then all three births, my own eyes saw the children of Lydia carrying heavy pain. I also picked them up gently, showing off to everyone in the family and some friends' , Carol Fairchild, Lydia's mother recounted in amazement and suffering. Dr. Leonard Dreisbach, obstetrician, is the first to receive three assertions for Lydia, and Lydia is the mother of all three children. He also said that Lydia's strange case certainly had some confusion in DNA test results. He is also very willing to testify in court about this 'truth' .

In terms of love, the panel members also believed that Lydia Fairchild was the mother of all three children. But logically, Lydia Fairchild has no proof that she and her children have the same blood. Lydia had hired a lawyer to defend her, but no one received it. Because they knew for sure, they couldn't win, the DNA results showed that. Finally, Lawyer Alan Tindell 'bravely' accepted the invitation. Because of his hunch, Lydia is not their kidnapper, but she is her mother.

People have DNA from various sources (Genetic Chimerism)

In that gloomy moment, a ray of hope suddenly flashed. Attorney Alan Tindell found an article in the New England Journal of Medicine , referring to a case in Boston similar to Lydia's. He applied to the court to postpone the trial when these tests could be done. That is the case of Karen Keegan, a 52-year-old mother with two sons in Boston. Testing before Karen's kidney transplant also showed that her DNA and children were not the same. The doctor there, despite knowing that there was no fake, could not explain what had happened. They performed tests in blood, hair, and oral tissues, but all did not have her son's DNA.

The doctors had a better understanding of Karen's thyroid. The reason doctors choose thyroid to test DNA because of 100ml of normal human blood, 2 - 2.5mm of calcium (100mg / l) and exist in 3 forms: 40% protein binding, 5 - 10 % is in the form of salt combined with phosphate, bicarbonate, citrate . and the remaining 50% exists in the form of ionization, to ensure the electrophysiological activity of the cells. Each day, the body absorbs into 25mmol calcium and eliminates 20mmol of + 5 mmol excretion into the urine. Thyroid hormones play a role in mobilizing calcium from the bloodstream and vitamin D helps absorb calcium into the body, leading to bone. Karen Keegan encountered a rare problem in medicine called chimerism .

This phenomenon occurs in humans or animals when two fertilized eggs or embryos combine together in the early stages of pregnancy. Each zygote carries a copy of the parent's DNA, so the new zygote has a different set of genes. Basically, the born child is the twin of itself. Human chimerism is very rare. In DNA tests to determine parents' offspring, a Chimerism case was discovered when the child was not biologically connected to the mother - it carried another DNA. Lydia Fairchild is a typical case that gave birth to a chimera. The young mother in Washington state struggled with the court to keep the baby whom she was carrying heavily.

Worldwide, only about 30 such cases are recorded. In fact it is the case that two twin individuals exist in one body. The reason is because two eggs are fertilized together, but when in the womb, they should be developed into two twins, they 'mix' together and become a single perfect fetus, but There are two different genetic codes - two different DNA sequences. In other words, Karen is two people in one body and that cannot be observed with the naked eye but can only be detected if genetic material is tested . That's why DNA around her body is different from her DNA, but her thyroid DNA is the same.

Karen's story prompted Lydia to convince the judge to give her more time. Finally, after a series of tests, the doctor concluded that Lydia was also a case of chimerism. The case file is closed with a happy ending: Lydia is recognized as the mother of her children and receives monthly benefits. Each time she remembered what had happened, Lydia still silently thanked Karen: 'Without her, I lost my child.'

Lydia's story is very well preserved in Washington state court court records. They see this as a rare 'medical case' . And the medical side and scientists especially are the research expertise on AND both in humans and animals, considering it a new step.
