Baby's DNA constructed before birth

Mom gave a blood sample. Dad spit. The entire genome of their fetus was born.

Researchers at the University of Washington have, for the first time, done a near-total genome sequence of a fetus in this way.  Scientists published the results of this study in the journal Science Translational Medicine, suggesting that thousands of genetic diseases could be detected in children while they are still in the fetal stage.

Everyone has two copies of the human genome: One inherited from their biological mother and one from the biological father. With technology that's being used for genetic sequencing these days, it's not possible to say which variants on the chromosome you inherited from which parent.

Scientists also sequenced the cell-free component of the mother's blood - called the plasma - where about 10% of the DNA circulating is from the child, and the other 90% is from the mother. That introduces some difficulty, since it's hard to tell exactly what comes from the child.

Currently at least some component of diagnosis for genetic disorders in certain circumstances is done using technologies such as amniocentesis, which involves taking a sample of the fluid in the sac that surrounds the fetus in the womb - the mother has to have a needle inserted into her uterus, which is a lot more complicated than a simple blood test and carries some health risks.

"This might reduce the need to do invasive testing for fetuses," said Jay Shendure, associate professor of genome sciences at the University of Washington.

The focus of the study was the genome of a fetus whose mother's blood sample was taken at 18 weeks. The analysis of her blood, the father's saliva and the plasma contributed to a nearly full picture of the fetus's genome.  This model showed that the fetus had 39 mutations that it had not inherited from either parent.

To confirm, researchers looked at the baby's umbilical cord blood after it was born. In comparing the constructed DNA (from mom & dad's samples) and this cord sample,  researchers found five additional mutations that hadn't come from the mother or the father.  On the whole, the baby's artificially constructed genome using material from the parents was more than 98% accurate.

Researchers repeated the procedure on a different couple. This time the mother was only eight weeks pregnant when she donated her sample, and the father submitted a blood sample, which was processed in the same way that the other father's saliva was. This resulted in a fetal genome sequence that was 92% accurate.

"We could have brought it higher just by sequencing her plasma more deeply," said Jacob Kitzman, lead study author and graduate research fellow at the University of Washington.

There are also parts of the genome that technology available today just cannot measure very well, Kitzman says, so that's partly why there's not a 100% accuracy here.

Is gender selection of a fetus ethical?

Eight weeks are, however, well before mothers are able to get amniocentesis, which is often used at around 16 weeks.

It took more than a month to get the results from the sequencing, which is a lot longer than would be ideal in a clinical situation, Kitzman noted. In order to become more widespread, the technique would have to be easier to administer, quicker and less expensive.

So how much does this cost? Right now, in the ballpark of $50,000, Shendure says - and while that seems like a lot, keep in mind that this whole process involved sequencing the genomes of the mother and the father, separately analyzing the plasma and then double-checking the result with a sequence from the child's umbilical cord.

The price tag for sequencing has dropped by 10,000 fold in the last five years, Shendure says, so he expects this fetal genome technique will also become less expensive over time.

In the long-term, the technique may even help garner new insights about genetic diseases, but more immediately it would be restricted to identifying the genetic disorders that we already understand, he said.

"Whether this is the sort of thing we would do on a widespread basis for all pregnancies, that’s an open question and a complex one," he said.

The complexity comes, of course, from the ethical issues that arise concerning parents who would selectively abort fetuses that are predestined for certain conditions.

The technology worries medical ethicist Harriet Washington, who fears parents could use genome sequencing to predict and selectively abort children that don't meet certain standards - not just for diseases, but for things like hair and eye color.

“If we don’t look at the dangers, if we adopt this Pollyanna attitude and only look at the benefits, then it’s really easy to end up in a situation where we are blindsided,” Washington said.

Perhaps one day, even intelligence scores or skills could be forecasted, creating a situation akin the movie "Gattaca" where babies are basically custom-created to suit the needs of parents who can afford the technology.

      God's hand is not in every little thing. God no more decides if an ant will be born with the right number of legs than he does a human baby. According to scripture, God gave man free will so he had the right to choose the path of good or not. Deciding for someone that they will have a crippling physical or mental disease is not free will. It is meddling. God does not make retarded babies. It is simply something that happens.

    To some people the ethics underlying this kind of research are horrifying. I think it makes sense to limit (by law) the information doctors can share once a genome has been sequenced then analyzed. Anything unrelated to the health or future health of an individual should be strictly off-limits. It will take some time and expertise to decide what is relevant and what is not. If they are only given the ability to share information regarding specific diseases then we don't even need to contemplate an entire generation of hand-picked babies. There are ways to navigate through the new information that genomic sequencing gives us without destroying the diversity that makes us human.

      I tend to think that people that think that "disease" is easily defined, and thus easily weeded out, are those that have only ever experienced "diseases" like the common cold. Is a fetus with Trisomy 21 "diseased" such that it should not be carried to term? What about fetuses that have explosions of neural growth associated with Autisim? I'd bet that those who have only ever had experience with those with Down Syndrome or Autism who were raised before these kids were treated like human beings (let alone given their best chance) fail to see the possibilities of the fetuses they are determining are diseased.

      What is frightening is that young medical students and doctors, without any idea of what a child or adult who is not typical can provide, are being taught that there is value in weeding these people (or fetuses) out (why else the push to identify the "imperfect?") For so long babies who were not typical were hidden away, not given the chance at just being kids, and not educated, such that everyone – including those who are doctors or medical students now – have no idea what these people have to offer and what they can be. At what point will the people, who aren't like everyone around them, have the chance to show what they can do for themselves, and what they can do for others? The truth is that these people not only suffer from the harm of stereotypes, but ones created by the fact that their parents and the doctors that could have actually helped them, were so selfish and heartless, that they conspired to lock these people away from anything and everything that would give them a chance.

      Just once, I would like a medical person to acknowledge the truth. The push to identify the "imperfect" before it is an embryo, fetus, or child, is because of the medical belief that there is a "perfect" and that anything less has less value. The Nazi's may personify it, but the medical establishment seems to embrace it without ever acknowledging that it is really just biological (as opposed to ethnic) cleansing.

      @ Sara – Assuming that it is "biological cleansing" (your arguments are in fact illogical, but I'll ignore that for now), so what? A fetus is not a person. The fact that it MAY become a person is irrelevant. I MAY win the lottery or get hit by a car tomorrow, but I do not treat those possibilities as facts. If we could create embryos free of genetic defects, I don't see the downside in that.

    As a physician I can tell you that whatever they actually did, the information in this article is so garbled in the reporting that it's incomprehensibe. Typical lousy CNN reportage. My best guess is that they looked at the father's and mother's DNA, compared it with what they found in the plasma that was different from either parent, and concluded that these were new mutations in the fetus. You absolutely cannot "construct" the genome of a fetus, which happens in the process of meiosis that creates the sperm and eggs and at the time that a particular egg and sperm unite at conception. Because of the recombination of each parent's chromosomes at meiosis, every egg and every sperm produced by each parent will have a different combination of those parents' genes, and thus each child that results will be different in a way that cannot be predicted (identical twins are simply clones, one product of conception split into two individuals). Thus, no one is creating something here; this is a garbled report of an attempt to look at genetic defects early on.

      They constructed it in the sense that they figured out the genomic sequence of the fetus, including haplotyping, which is REALLY hard. The trick is figuring out what fraction of the DNA free-floating in the mother's bloodstream is different from the mother's own DNA, then map the haplotypes of that DNA back to the mother and the father.

    I'm still uncertain how this test has anything to do with the fetus. They take blood from mom, spit from dad... why does mom even have to be pregnant? And how is this predictive of the individual child? Brothers and sisters would have identical results. So this test to me seems to only predict the genetic makeup of all of a couple's potential offspring, not a specific individual.

      Spit from the father is for differentiating mother's genes and the fetuses. Basically what happens when a child is in the womb cells from the fetus while it is growing expire and then the mother's body then recycles them (essentially breaks them down for nutrients) The same process that happens within us all the time. This blood test picks them up when they are in the mother's plasma. Of course then what happens is that there is no "filtration" of the DNA, the cells from the sample are all burst and any DNA is removed, which includes the DNA from the fetus and the mother. The doctor's know the mother's genome. Anything that is in there that is not from the mother must be from the fetus, different regions can be from the mother, and others can be from the father. The father's DNA in combination with the mother and fetuses DNA is analysed to construct the fetuses genome, this is why there is a loss of accuracy.

      Brothers and sisters will NOT have identical results. Each gamate (sperm and egg) contains a unique genome, when a sperm cell fertilizes the current egg, the fetus consists of chromosomes from the father, and the mother. Each gamate contains a unique mix of the parents the mother, and the parents of the father.

      Except they don't actually know the mother's DNA, since they didn't sequence it before she got pregnant. They had to deconvolute what came from the mother and what came from the fetus based on sequencing their DNA pooled together.

      Second of all, all birth defects have man-made causes? Yes, some do. But not all. Some are caused by spontaneous genetic mutations. But then, maybe you think we should go back to the time when there were no antibiotics to treat diseases that used to kill millions, and no treatments for cancer, in fact, no treatments that kept pre-maturely born babies alive! God's will and all that. OR, maybe if God does exist (I don't know for sure), he made humans with thinking minds that could come up with these treatments.

    I would pose a question: What about the parents that would welcome a child regardless of disease or deffect? Would this information not allow them to make choices in terms of finance, logistics, etc that might mitigate the difficulty posed by thier child?

    Its not a simple problem and won't have a simple solution but keeping information from people, regardless of intent, often does more harm than good.

    "G-A-T-T-A-C-A, give me a G-A-T-T-A-C-A!" or "KHAANNN"!!!!!-Anyway, I have always thought that genetic engineering and desinger genes would become a huge thing in this century and onward, but we should be careful to keep this science in reason. The science is a tool, but it is only our actions that will cause damage not just on an ethical scale, but on our evolution as a species as well...so the best answer is that we at least elimanate some deadly genetic diseases, but we should be careful beyond that. When does genocide occur if no one is getting killed but we are tweaking ourselves so much that it backfires and we elimante things that could be beneficial to humanity? It is not that we shouldn't do this, but we have to be careful and realize we are walkng a very fine line with this as well...but I have to say, it is an amazing problem to have in reality today, isn't it?

    This discovery should keep the religious right nut cases busy for awhile.
    Too bad that they can't grasp the concept that God gave us brains and He hopes that we can now use this gift to prevent the misery of bringing damaged children into the world.
    Oh wait, if we prevented the births of brain damaged children, then there would be no religious right.

    One Step Forward for Parents to be....Two steps back for Humans to be.

    I think this can be deadly for unborn fetus'....remember the case of the parents who sued the doctor for misdiagnosing their baby with down's syndrome, where they said they would have aborted the baby otherwise. The doctor accidentally took blood samples from the placenta and not the fetus. There's good and bad implications in this.

    what i found interesting is the fetus had 39 mutations that it had not inherited from either parent, with 5 more being found after birth. having had a child who died of a rare immune deficiency–with no known family history and two siblings who continue to be healthy–I often wondered if his mutation was a mix up in utero. our DNA was also sequenced but what good did that do us when science hasn't caught up yet? Doctors and researchers have no idea what all the mutations mean so its hard to say where his came from. Waiting for the day science catches up so we'll have an answer. Doesn't bring our boy back but maybe it'll help other families so they don't share our same fate.

      Mutations can be good, bad, or neither. When they throw around a number like that it is just a way to just how different something is. In entertainment they have done a great job of making mutations seem like something that is always bad.

    Did these parents KNOW that their cord blood was being used in this experiment? I was told even if you save your childs cord blood and pay for it they (the hospital) can still use it without your consent when my son was born. Coincidentally my wife who got temporary state assistance and is a stay at home mother was sent to the geneticist and was told it was because she was 40 years old when we had our first child. How many other pregnant women getting government aid has this happened to? What are the peoples names who participated? I question the ethics for sure.

      clearly the parents participated in the study... unless, of course, they stole the dad's spit and the mom's blood without them knowing. You really think a major research university is going to publish a study where they stole umbilical cord blood? This isn't HELA cells we're talking about.

      It is standard practice for anyone over 35 to be referred to a genetic counselor. she had the option of saying no.

      Tracy, in TX, they do forcefully withdraw blood from each baby born in a hospital for general research. Much of that blood is sent to the US military (scary). A piece of my baby was stolen, without my consent. They do this, you are not allowed to refuse consent.

    This will prevent a whole lot of heartbreak, or 98% of heartbreak. If the information is provided to parents only for serious diseases, I'm OK with that. If parents use it to selectively abort fetuses who will not be not tall enough or won't have the desired hair color, that needs to be a firm NO.

    In fact, I can see this becoming a part of eHarmony-type of match-making websites, where people hook up only with "genetically healthy" partners. And that's fine too.

    I totally agree with using this informatin to make human lives better, to make life longer and healthier. However, I also feel we need to look at birth control if we are going to meddle with the human genome and human longevity. Otherwise we are just pouring water into a full pitcher.

    For those religious people out there: "God" has entrusted us with these gifts and we have a responsibility to use them wisely. If we don't we will be punished...or whatever. Either way...GOD will determine what is right or wrong...not some zealot fundamentalist Christian who read a 2000 year old book and thinks they have all the answers. (And by "God" I mean budda, allah, Set, mother nature, the giant purple spaghetti monster, monday night football...whatever "thing" you look to for answers when you are to scared to seek them out yourself...)

    TYPE ALEF:
    The man who had received the five talents brought the other five. 'Master,' he said, 'you entrusted me with five talents. See, I have gained five more.' "His master replied, 'WELL DONE, good and faithful servant! You have been faithful with a few things; I will put you in charge of many things. Come and share your master's happiness!'

    TYPE GIMEL:
    "Then the man who had received the one talent came. 'Master,' he said, 'I knew that you are a hard man, harvesting where you have not sown and gathering where you have not scattered seed. So I was afraid and went out and hid your talent in the ground. See, here is what belongs to you.'" His master replied, 'You WICKED, lazy servant! So you knew that I harvest where I have not sown and gather where I have not scattered seed?

    Which of the following is the type Alef servant and which is type Gimel?

    1.

We will divest our obligations and isolate our riches from the undeserving because biblically speaking each of us should take care of our own sickness and health.

    This technology is amazing and should be developed for all. No one is going to abort a fetus for eye color or hair color. But, it will allow parents to make informed decisions to would keep a child from being born with debilitating diseases or conditions.
    And, if anyone thinks that's 'playing God', doctors said the exact same thing about organ transplants and artificial hearts once. Now, we consider them without negative connotations. We as a species must move forward, even if that means redefining our own definition of humanity along the way. We have been playing God since the day we invented novacain and aspirin....

    As the father of a child with a rare Genetic Disorder resulting from a spontaneous mutation in a single gene, I can tell you that even being 98% or better in accuracy doesn’t mean a lot when it only takes 1 little change to have drastic consequences.

    I don't see any value in this and would rather people focus on just being happy to be able to have a health baby.

    Since chimps and humans are, on average 96% the same, the, "more than 98% accurate" sequencing of the first case and the, "92% accurate" sequencing in the second case leave quite a bit to be desired.

    My issue is whether or not parents have a right to know everything about a child's genetics before the child knows. I'm not sure that putting parents in the position of having to decide when to reveal something to a child is a good idea. What if, in the future we are able to know before birth that a child will have a good chance for getting ovarian cancer. When do parents tell that to their child? Do they tell her in an attempt to get her to having children early, or do they tell her in an attempt to get her to never have children? Or do they tell her just because they should? Or not tell her because they shouldn't? I wouldn't want to be put in that position.
