What Are Genetic What Are Genetic DefectsDefectsGenetic disorders are genes of a baby are Genetic disorders are genes of a baby are

corrupted. They occur when recessive and/or corrupted. They occur when recessive and/or dominant genes are passed down to the baby dominant genes are passed down to the baby

from generation to generation. A genetic disorder from generation to generation. A genetic disorder could also occur when a baby has too many, too could also occur when a baby has too many, too little, or damaged chromosomes. A baby with a little, or damaged chromosomes. A baby with a

genetic disorder has a certain problem such as a genetic disorder has a certain problem such as a disease that is either in its genes to pass down to disease that is either in its genes to pass down to

Genetic defects are abnormalities in a baby’s health particularly in its body’s abnormalities in a baby’s health particularly in its body’s function or structure. This is why the babies have mental or function or structure. This is why the babies have mental or physical problems. Did you know? When babies are living their physical problems. Did you know? When babies are living their first year of life, genetic defects are the leading cause of death. first year of life, genetic defects are the leading cause of death. Most babies experience a shortened life if they inherit a genetic Most babies experience a shortened life if they inherit a genetic defect. Most genetic defects cannot be stopped from happening defect. Most genetic defects cannot be stopped from happening in a baby. Babies are born with genetic defects because of in a baby. Babies are born with genetic defects because of genetic and environmental reasons or because of damaged or genetic and environmental reasons or because of damaged or more than enough chromosomes which babies inherit from their more than enough chromosomes which babies inherit from their parents. These genetic and environmental reasons impact how parents. These genetic and environmental reasons impact how the baby is born and produce genetic defects. It’s pretty hard to the baby is born and produce genetic defects. It’s pretty hard to believe that each year in the United States, 120,000 babies are believe that each year in the United States, 120,000 babies are born with genetic defects. Genetic defects affect 1 out of every born with genetic defects. Genetic defects affect 1 out of every 28 babies. Until a child grows, most genetic defects aren’t clear. 28 babies.

Genes in parents affect how babies are born. There is a 3 to Genes in parents affect how babies are born. There is a 3 to 4% chance that parents will have a baby with a genetic 4% chance that parents will have a baby with a genetic defect. The percentage rises if the baby has a family history of defect. The percentage rises if the baby has a family history of genetic defects. If both parents are carriers to a certain genetic defects. If both parents are carriers to a certain disease, their child has a 25% chance to have the disease disease, their child has a 25% chance to have the disease when born. There are recessive and dominant genes in when born. There are recessive and dominant genes in everybody. For example, brown eyes are dominant over blue everybody. For example, brown eyes are dominant over blue eyes. These genes determine how severe or if the baby will eyes. These genes determine how severe or if the baby will have the genetic defect. There are many different types of have the genetic defect. There are many different types of genetic defects and the 70% of them don’t have a known genetic defects and the 70% of them don’t have a known cause. Examples of genetic defects include spina bifida, cause. Examples of genetic defects include spina bifida, cystic fibrosis and Down syndrome.

Screening TechniquesScreening Techniques There are a variety of 3 screening techniques to detect birth defects. There are a variety of 3 screening techniques to detect birth defects.

The first one is ultrasound, which uses sound waves that can’t be The first one is ultrasound, which uses sound waves that can’t be heard by the human ear to detect genetic defects. It is a non-invasive heard by the human ear to detect genetic defects. It is a non-invasive way to detect big problems in growth development. The downside is way to detect big problems in growth development. The downside is that is that you cannot check for genetic defects because the that is that you cannot check for genetic defects because the ultrasound doesn’t zoom in unless we upgrade the ultrasound greatly. ultrasound doesn’t zoom in unless we upgrade the ultrasound greatly. The second technique amniocentesis, which uses a large needle to The second technique amniocentesis, which uses a large needle to collect 20 ML of amniotic fluid. It is an invasive once the fetus has collect 20 ML of amniotic fluid. It is an invasive once the fetus has been carried for 16 weeks and it takes 2-4 weeks to get the results. been carried for 16 weeks and it takes 2-4 weeks to get the results. After deciding to use amniocentesis, you cannot consider to abort the After deciding to use amniocentesis, you cannot consider to abort the birth though it can detect all abnormalities by mapping up birth though it can detect all abnormalities by mapping up chromosomes and gives a 0.5% of miscarriage. Miscarriage is the risk chromosomes and gives a 0.5% of miscarriage. Miscarriage is the risk of damaging the fetus with the needle. An amniocentesis can also of damaging the fetus with the needle. An amniocentesis can also produce infection, leakage, and other complications such as produce infection, leakage, and other complications such as preterm preterm labor and delivery, respiratory distress, postural deformities, fetal labor and delivery, respiratory distress, postural deformities, fetal trauma and alloimmunisation (rhesus disease)trauma and alloimmunisation (rhesus disease). The final technique of . The final technique of testing is CVS. It is also invasive but it works 8-12 weeks of carrying testing is CVS. It is also invasive but it works 8-12 weeks of carrying the fetus. It can detect the same things as an amniocentesis but the the fetus. It can detect the same things as an amniocentesis but the risk of miscarriage is 1%. Not only there is a chance in miscarriage, but risk of miscarriage is 1%. Not only there is a chance in miscarriage, but there is a chance of infection and amniotic fluid leak. The result of the there is a chance of infection and amniotic fluid leak. The result of the leaking fluid causes leaking fluid causes olighydramnios which can end up as a baby having olighydramnios which can end up as a baby having underdeveloped lungs (Hypoplastic lungs). If the baby develops underdeveloped lungs (Hypoplastic lungs). If the baby develops hypoplastic lungs, the lungs don’t have a chance to mature, and the hypoplastic lungs, the lungs don’t have a chance to mature, and the baby can die shortly after birth.baby can die shortly after birth.

What we studied Our group studied X-DNA, Quantum Dots, the Circulatory System forming in a baby inside a mother’s body, DNA, Genetics, Viruses, about the baby’s surroundings in a mother’s body.

X-DNA is wider than regular DNA by 20%!

Can Quantum Dots make the genetic defect in a cell light up?

Will injecting a virus into a mother’s bloodstream be successful one day?

Just the little risk of miscarrige in the tests for genetic defect testing that are already Just the little risk of miscarrige in the tests for genetic defect testing that are already developed, (amnio. = .5% and CVS = 1%) is enough to scare the parents so they do developed, (amnio. = .5% and CVS = 1%) is enough to scare the parents so they do the genetic defect testing. So if we did use very powerful microscopes, genetic the genetic defect testing. So if we did use very powerful microscopes, genetic testing would work without the risk of miscarrige, also at an earlier time than CVS and testing would work without the risk of miscarrige, also at an earlier time than CVS and amniocenthesis. This encourages most people to get themselves checked and make amniocenthesis. This encourages most people to get themselves checked and make sure their kids will not inheret a genetic defect.sure their kids will not inheret a genetic defect.

Possible solution #3: Non-Possible solution #3: Non-Invasive Method To Test For Invasive Method To Test For Genetic DefectsGenetic Defects

Invasive methods of testing fetuses for genetic defects Invasive methods of testing fetuses for genetic defects could cause a small risk in miscarriage that could have could cause a small risk in miscarriage that could have some people change their minds about testing. Other some people change their minds about testing. Other methods can be used that are non-invasive and pose no risk methods can be used that are non-invasive and pose no risk of miscarriage at all, especially a blood test for the mother. of miscarriage at all, especially a blood test for the mother. In the first five weeks of the baby’s development, the In the first five weeks of the baby’s development, the placenta starts to lose and shed its cells, which contain the placenta starts to lose and shed its cells, which contain the baby’s DNA, into the mother’s bloodstream. If we take the baby’s DNA, into the mother’s bloodstream. If we take the mother’s blood and search for those cell fragments, we can mother’s blood and search for those cell fragments, we can find the baby’s DNA and test that for any genetic defects find the baby’s DNA and test that for any genetic defects without using the invasive methods. But these fragments without using the invasive methods. But these fragments cannot determine the final gene set of the baby, because cannot determine the final gene set of the baby, because the gene activity in various organs can slightly change the gene activity in various organs can slightly change without reflecting that change in the placenta’s DNA. So for without reflecting that change in the placenta’s DNA. So for this reason this method would not substitute the invasive this reason this method would not substitute the invasive and alternate methods, since it will not determine the and alternate methods, since it will not determine the baby’s resulting DNA set, compared to getting the original baby’s resulting DNA set, compared to getting the original set from the baby’s own cells. set from the baby’s own cells.

Final SolutionFinal Solution

For this method we will take a non For this method we will take a non pathogenic virus, which will target a pathogenic virus, which will target a specific cell, and insert it into the specific cell, and insert it into the mother’s bloodstream. It will then mother’s bloodstream. It will then pass through to the baby and into one pass through to the baby and into one of its cells.of its cells.

Description of the Description of the ProcessProcessThis new method for testing for genetic defects in fetuses will be done by using a non-This new method for testing for genetic defects in fetuses will be done by using a non-

pathogenic and harmless Virus Vector, which will target a specific cell in the body of pathogenic and harmless Virus Vector, which will target a specific cell in the body of the fetus. This virus will contain polymerase to break apart the strands of DNA on the fetus. This virus will contain polymerase to break apart the strands of DNA on the needed gene, artificial RNA that would render a translated protein useless, and the needed gene, artificial RNA that would render a translated protein useless, and possibly Ribozyme (an enzyme that can join two segments of RNA). To transport the possibly Ribozyme (an enzyme that can join two segments of RNA). To transport the virus to the fetus, it will be injected into the mother’s bloodstream where it will, in virus to the fetus, it will be injected into the mother’s bloodstream where it will, in about 30 minutes, pass through the mother’s placenta unnoticed (because the virus about 30 minutes, pass through the mother’s placenta unnoticed (because the virus will be a kind that can’t be detected by the immune system) and enter one of the will be a kind that can’t be detected by the immune system) and enter one of the cells in the fetus. Upon entrance the virus will completely break apart in the nucleus cells in the fetus. Upon entrance the virus will completely break apart in the nucleus and release all of its components. The Polymerase will separate two strands of DNA and release all of its components. The Polymerase will separate two strands of DNA of a specific gene, and with the use of one of the DNA strands and free nucleotides, of a specific gene, and with the use of one of the DNA strands and free nucleotides, it will build one complementary strand called RNA (which in comparison to DNA will it will build one complementary strand called RNA (which in comparison to DNA will have Uracil in its sequence instead of Thymine). Meanwhile the artificial RNA from have Uracil in its sequence instead of Thymine). Meanwhile the artificial RNA from the virus will attach to the newly finished RNA right before the stop codon, possibly the virus will attach to the newly finished RNA right before the stop codon, possibly with the help of the Ribozyme from the virus. This altered RNA will mature into with the help of the Ribozyme from the virus. This altered RNA will mature into messenger RNA, which will then transport itself outside the nucleus and to the messenger RNA, which will then transport itself outside the nucleus and to the nearest ribosome. This ribosome will translate the mRNA sequence and gather nearest ribosome. This ribosome will translate the mRNA sequence and gather specific amino acids based on it, until it encounters the stop codon in the sequence. specific amino acids based on it, until it encounters the stop codon in the sequence. When the chain of amino acids is finished it will separate from the ribosome and fold When the chain of amino acids is finished it will separate from the ribosome and fold itself into a protein. Since this protein was translated from the specifically altered itself into a protein. Since this protein was translated from the specifically altered RNA, it will be dysfunctional and be ejected from the cell and into the bloodstream. RNA, it will be dysfunctional and be ejected from the cell and into the bloodstream. Afterwards it can be detected by simple blood tests and decoded back into the Afterwards it can be detected by simple blood tests and decoded back into the original RNA sequence (of course you would also have to exclude the decoded original RNA sequence (of course you would also have to exclude the decoded sequence of the attached artificial RNA). Lastly, the RNA can be analyzed and sequence of the attached artificial RNA). Lastly, the RNA can be analyzed and checked for any genetic defects, and you can finally know if the fetus has any checked for any genetic defects, and you can finally know if the fetus has any genetic defects on a specific gene. genetic defects on a specific gene.

I like to play tennis, piano, and study science and mathematics. I go to Old Orchard Junior High School as an eighth grader, where I also participate in Science Olympiad. Sometimes I enjoy writing narrative essays and just writing poems in my spare time. My favorite sports in the summer are playing tennis, soccer, and swimming. In the winter, I go skiing on snowy hills in Kenosha, Wisconsin. I have enjoyed this wonderful school year so far, and it has been a pleasure being in TechXplore.

Hello Everyone,Thank you for contacting me for the project. I am happy to know all ofyou and excited about being a part of TechXplore project.

At the moment, I don't have answers to all your questions however I willtry to help address each as quickly as I could.

I can answer your one question below:5)What do you do for a living and how long have you been doing you job?I am an electrical engineer working for Hewlett-Packard (HP) for almost13 years. I have 20 years of experience as Hardware design engineerdesigning laptop computers.

Genetic is new topic for me so I will need to research before I can helpyou with all the questions.

These are very good questions!

I like to know following:1) Do you have any timeline or project guideline defined for thisproject?2) Do you have focus statement for the project?3) Have you put any material on TechXplore website that I can getfamiliarizes with?

Please reply back with the answers to my question and any additionalquestions you may have.

Thank you!Rahul Lakdawala

ii) There are many different genetic defects that can be detected beforebirth, but very few can be cured. One condition, Rh incompatibility canbe treated through Rh-immune globulin injections.Some of the questions that parents need to ask themselves with geneticresults are:-How accurate are the test results? (is it possible there is a mistake?)-Can the baby survive this condition? How long will he live?-What problems might be caused by the condition?-What is involved in caring for the child with this condition? etc

4)Could we test the umbilical cord for a genetic defect instead oftaking a sample of amniotic fluid from the amniotic sac?

i) Yes, there are cells from the child in the umbilical cord (like stemcells). But I think it is much more difficult to remove cells from theumbilical cord then amniotic fluid.

ii) Percutaneous umbilical blood sampling is used when rapid chromosomeanalysis is needed, particularly toward the end of pregnancy whenultrasonography has detected abnormalities in the fetus. Often, resultscan be available within 48 hours.

There are greater risks to mother & fetus than testing amniotic fluid.

5)What do you do for a living and how long have you been doing you job?

6)Are there any alternate ways instead of sampling amniotic fluid totest for genetic defects?

i) For inheritable diseases, yes. The genetic make-up of each parentcan be determined and the risk of the child having the disorder can beobtained (I think a lot of couples do this to test for tourettessyndrome). Or after the child has been born, there can be genetictesting to determine if there are any genetic defects.

ii) Another common method takes a biopsy of the placenta (called CVS).The risks were thought to be higher in the past, but are proving to beequivalent to sampling amniotic fluid.


i) We can probably test for any genetic disorder that scientist know thecause of, for example which gene is defective in CF or which chromosomeis extra in down syndrome patients, then they can test for it. But inorder to test for these diseases they must have cells from the baby,which is usually taken from the amniotic fluid or umbilical cord.Genetic disorders are not curable. Genetic disorders are caused by adefect in every single cell in your body, it is at the genetic level.There has been some research attempts trying to use gene therapy to"cure" genetic disorders, but there are many challenges that researchersare trying to overcome. One area of intense research is with diabetespatients (One type - I believe type II - is a genetic disorder). Yetthere is still no current therapy on the market. There are medicinesout there to help reduce the symptoms or side effects of some geneticdisorders.

Sent: Friday, November 09, 2007 12:55 PM Hi, I am Anosh replying for my team. One question my team had for youis: Do you know if laser or microscope techonology can zoom into celllevel so we can look at genes and check for genetic defects that way?Thank you so much for your answers so far.Sincerely, Anosh

Sent: Saturday, November 10, 2007 3:15 PM Hi Anosh,Thanks for responding to my email.I am still checking on one more thing on your question but so far this is what I have.Laser is used for destroying cell and can't be applicable to zoom in to view the cells.Microscopic technology can be used to view chromosome is possible but I don't believe at the level of genes. I am confirming that but at this point this is what I think.

Let me know if this helps answer your question or not.

How is project going?Are you on track?How can I find out more about the project status and what the team has developed so far?Please let me know....


Hi Everyone,I tried looking for different microscope technology however I didn't find anything that can meet this application.

Please let me know your response to the questions I asked in last email. Thanks and let me know if I could be of any assistant.

Happy Thanksgiving to all!
