NPR: Clinic Claims Success In Making Babies With 3 Parents’ DNA

Nadiya Clinic in Kiev, Ukraine, is creating babies using the DNA of three people. The procedure can help women who are infertile have children.

In a clinic on a side street in Kiev, the capital of Ukraine, doctors are doing something that, as far as is publicly known, is being done nowhere else in the world: using DNA from three different people to create babies for women who are infertile.

"If you can help these families to achieve their own babies, why it must be forbidden?" Dr. Valery Zukin, director of the Nadiya Clinic, asks as he peers over his glasses. "It is a dream to want to have a genetic connection with a baby."

I traveled to Ukraine because Zukin promised unusual access to his private fertility clinic, including the first demonstration for a U.S. journalist of how scientists create "three-parent" babies — a procedure prohibited by the U.S. Food and Drug Administration.

Zukin also arranged the first-ever interview with a mother of a 15-month-old boy who is one of the four children he says he has produced this way.

Three more of his patients are pregnant, Zukin says, including a woman from Sweden. Women from several other countries including Britain, Brazil and Israel are going through the process, he says.

Leading ethicists and genetics researchers criticize the clinic for rushing ahead to use this method for infertility. No one knows whether children produced this way will be healthy, they say. And some worry the procedure may open the door to "designer babies."

"This is pretty troubling," says Marcy Darnovsky, who heads the Center for Genetics and Society, a U.S.-based watchdog group.
But Zukin dismisses those criticisms.

"As a doctor I understand only one thing: We have parents who couldn't have children and now they have their own biological child. That's all," Zukin says.

Zukin has helped form a company, Darwin Life-Nadiya, with a New York clinic to market the service to U.S. women willing to travel to Ukraine. Ukrainian women pay about $8,000 for the procedure; for foreigners, it's about $15,000.

Moving too fast?

Some scientists are welcoming this as a potentially exciting new option for some women.

"It is pioneering work," says Dietrich Egli, an assistant professor of developmental biology at Columbia University Medical Center in New York. The procedure is technically known as "pronuclear transfer."

"What we can learn from their work is that pronuclear transfer may be useful for some cases of infertility," says Egli.

But critics say it's far too soon to be attempting this procedure to create children.

"This is really an irresponsible kind of human experimentation," Darnovsky of the Center for Genetics and Society says.

Not nearly enough laboratory and animal research has been done to know if the procedure is safe, Darnovsky and others say.

"We just don't know what's going to happen to these children," Darnovsky says.

In the 1990s, a doctor in New Jersey injected fluid from healthy eggs into the eggs of infertile women, and some babies were born with mitochondrial DNA from three people. But that was discontinued after the FDA intervened.

Only one other baby is known to have been produced using a technique similar to the one being used by Zukin. John Zhang of the New Hope Fertility Center in New York performed a related procedure for a Jordanian couple to try to prevent their child from having Leigh syndrome, a disorder caused by defects in mitochondrial DNA.

That's why the procedure was developed — to help women carrying mitochondrial disorders have healthy children. In severe cases, these disorders can be fatal.

A U.S. National Academy of Sciences panel concluded it could be ethical to attempt the procedure for this purpose. But because the FDA won't allow it at all in the United States, Zhang went to Mexico as part of his effort to create the baby for the Jordanian couple in 2016.

Doctors in the United Kingdom have started trying the technique to prevent mitochondrial disorders. But the British doctors are being allowed to try to make only one baby at a time as part of a tightly regulated research program.

Zukin says he received approval for a five-year research program from the Ukrainian Postgraduate Medical Academy, which is under the auspices of the Ukrainian Ministry of Public Health. But Zukin concedes the procedure is far less regulated in his country. Nevertheless, he makes sure all the women understand they are undergoing an experimental procedure.

"We explain everything to the families. And not all families give permission for providing this experimental procedure," he says.

Because mitochondrial DNA can be inherited, Darnovsky worries the procedure is crossing a line that long has been considered taboo: making changes in human DNA that can be passed down to future generations. One fear is that a mistake could create a new disease that could be inherited.

Mitochondrial DNA is inherited from the mother. Zukin already has used the procedure to produce one baby girl — a girl who could one day pass the mitochondrial DNA to her own children.

Darnovsky worries the procedure could also open the door to creating babies who are genetically modified for other reasons.

"What we're seeing is a fast slide down a very slippery slope toward designer babies," Darnovsky says. "We could see parents feeling eager to give their children traits like greater strength, needs less sleep. Some people are saying that, 'Yes, there are genes for IQ and we could have smarter babies.' "

Zukin dismisses speculation about designer babies. He says he's interested only in helping women who are infertile have genetically related children or prevent mitochondrial diseases. And so far, all the babies he has created appear to be perfectly healthy, he says.

The only way to know whether the procedure works and is safe is to try it, he argues. He hopes to figure out how to make the procedure work for women suffering from age-related infertility as well, which would help far more women.

"If you would like to swim," he says, "then, first of all, you must jump in the water."


NPR: Її син один з небагатьох, хто має ДНК від трьох батьків

Marina Muun for NPR

Лікарі у Клініці НАДІЯ допомогли організувати зустріч із Тамарою, мамою першого малюка від трьох батьків. Тамара, це не справжнє ім’я. Вона попросила змінити її ім’я, щоб зберегти конфіденційність.

Сидячи за столом у тісній, але дуже затишній квартирі у Харкові, Тамара почала розповідати свою історію.

«Шість років тому я зустріла свого чоловіка, і через півроку ми почали наші спроби народити дитину», - каже вона.

Але завагітніти не могла. І тому з року в рік, цикл за циклом вона проходила процедуру екстра корпорального запліднення. Це було виснажливо, емоційно. І нічого не виходило.

«Мені було дуже сумно, і в деякі моменти я навіть втрачала надію», - говорить вона. «Але тоді ви знаходите в собі сили. Тому що мати дитину - це мета, яку ви не можете втратити».

Потім вона дізналася про клініку в Києві. Лікарі розповіли їй про щось нове. «Вони показали нам фотографії про те, скільки генів буде мати дитина «від трьох батьків», - говорить вона.

Лікарі запліднюють одну з її яйцеклітин спермою чоловіка. Потім вони  використовую сперму її чоловіка, щоб запліднити яйцеклітину іншої жінки-донора. І тоді науковці видаляють більшу частину ДНК із заплідненого яйця іншої жінки-донора і заміняють її ДНК Тамари та її чоловіка.

«Моя перша реакція була:«Вау, як наука так далеко дійшла?», - говорить вона. «Неймовірно, що вони можуть зробити такий матеріал. Це чудово і неймовірно».

Ідея полягає в тому, що щось в яйцеклітини від іншої жінки може відігравати визначну роль. Це може бути крихітна частина генетичного матеріалу, відомого як мітохондріальна ДНК. Ці 37 генів є така собі схема мітохондрій, силових структур всередині клітин, які забезпечують енергію для яйцеклітини та ембріонів.

Цей метод був спочатку розроблений, щоб допомогти жінкам, які переносять руйнівні генетичні порушення, викликані дефектами в мітохондріальній ДНК, уникнути передачі цих генів їх нащадкам.

Дитина Тамари матиме ДНК від трьох різних людей: Тамари, її чоловіка і жінки, яка пожертвувала яйцеклітину. Але це не турбувало пару.

«Я знала, що ця маленька частина ДНК не вплине на такі важливі речі, як колір очей, колір волосся, характер та все інше», - говорить вона про ДНК донора.

Тому пара вирішила це зробити. І це спрацювало. Вперше у своєму житті Тамара змогла отримати здоровий ембріон, завагітніти, почути, як серце її дитини б'ється в її утробі і в кінцевому підсумку народити дитину.

«Було багато посмішок, багато сліз щастя, я не можу описати це», - говорить вона. «Це як ... щастя відчуває». Її синові зараз 15 місяців.

У той час як Тамара в захваті від результату, є великі побоювання з приводу процедури і її довгострокових ефектів. Найбільший: чи безпечно це? Сьогодні її син виглядає абсолютно здоровим. Але хто знає, що може з'явитися через кілька місяців або років? Де може рутинне використання цього методу?


NPR: Her Son Is One Of The Few Children To Have 3 Parents’ DNA

Marina Muun for NPR

On the third floor of a big Soviet-era apartment building in Kharkiv, Ukraine, the mother of one of the world's first babies created with DNA from three different people cracks open her door.

"Hello; my name is Tamara," she whispers, to avoid waking her son from his nap.

Her name isn't really Tamara. She asked me to call her that to protect her family's privacy. She knows how unusual — and controversial — her baby might be to some people.

Doctors at the Nadiya Clinic in Kiev, which created her baby, arranged for Tamara to become the first mother of a "three-parent baby" to give an interview to a journalist.

After settling down at the kitchen table in her cramped, tidy apartment near the Russian border, Tamara starts telling her story. She's 31 and always wanted kids.

"Six years ago, I met my husband and in six months we started our tries to bring a child," she says, speaking through an interpreter.

But she couldn't get pregnant. So she went through round after round of in vitro fertilization, year after year. It was a grueling, emotional roller coaster. And nothing worked.

"I was quite sad. And at some moments I even lost my hope," she says. "But then you find some forces in yourself and some emotions. Because to have a child is a goal which you couldn't drop."

Then she heard about the clinic in Kiev. Doctors there told her about something new. "They showed us pictures for how many genes the child would have" from the three parents, she says.

The doctors would fertilize one of her eggs with her husband's sperm. Next, they would use her husband's sperm to fertilize an egg from another woman paid to donate eggs. And then the scientists would remove most of the DNA from the other woman's fertilized egg, and replace it with Tamara's and her husband's.

"My first reaction was: 'Whoa! How [has] science got so far?' " she says. "It's unbelievable that they can make such a stuff. It's wonderful and unbelievable."
