Autism is a disorder marked by impaired social interaction and communications. Researchers are using the genetic findings as the beginning,then followed up by studies to see how and where the products of how genes work in the brain. Scientist are searching for single changes in the DNA, called individual point mutations, scientists hope to fill in the rest of the genetic components that contribute to autism risks. Other scientists are looking at differences in gene activity to find biochemical markers for early treatments.the irregular gene activity patterns can be used to help find high-risk children as when their babies, instead of at age 2 or 3, we can allow early therapies to be initiated. Studies show that the younger the child, the more flexible the brain. With intense behavioral interventions, new mental pathways can be created to overcome some of autism’s effects.
ReplyDeleteAutism is thea pervasive developmental disorder of children, characterized by impaired communication, excessive rigidity, and emotional detachment. To try to untangle these complications, researchers are using the genetic findings as a starting point, followed up by studies to see how and where the products of these potentially rogue genes work in the brain. Other laboratories are using new technologies to sequence all protein-coding regions and even all of a person’s DNA to identify parts of the genome that diverge in people with autism and healthy subjects. Researchers then began looking for rare variants in autism — and found them.
ReplyDeleteAutism is a very common symptom you see in many people these days. Autism might just seem that it would simply come from genetics, but it is a far bigger mystery then just that. Scientists have still not found a pure significant reason for what truly causes autism. Although there may be some clues on what may cause it (genetic mutations, genes, etc.) there is no real reason. So far scientists have discovered many DNA factors/notices in autistic kids that they also have found in regular people. They will usually run tests on them through blood samples and other forms of that matter.
ReplyDeleteAutism is a spectrum of socially inept disorders, in which some signs are the inability to read social cues, over reactions to certain things, and they often times have trouble keeping eye contact. Scientists are testing which genes or gene mutations are responsible for autism. They are testing both healthy subjects and ones with a form of autism, by looking at their genes and seeing what the differences are. They are using DNA to observe the codons that are responsible for autism. So far, there are many different genetic modifications that could be linked to autism somehow, but only a few are actually present in most cases of autism. This is causing some confusion so scientists are plaining on going deeper on the subject. Knowing what genetics are responsible might allow scientists to flag a predisposed person, allowing early intervention, almost an infant, rather then having to wait for signs of autism later on.
ReplyDeleteAutism is a disorder that is somewhat common and it's when someone has issues with speaking and social interactions. Scientists have found that 90% of autism comes from your genes. Some of the genes that are in autistic kids and adults are also in non-autistic people. Autism comes from a unlikely mutation in a persons genes. Since scientists have found new reasons for the cause of autism they are coming up with new ways to help with autism at an earlier stage. Some things that stands out about people with autism is that they have a hard time keeping eye contact, they have a hard time talking, and they are distracted by things easily. The ratio for autism is about 1 to every 110 kids in the United States. Scientists who have been researching autism have found that many genes can bring up the chances of having autism.
ReplyDeleteIn the past year, scientists have found rare genetic mutations that may contribute to autism. Scientists are using new DNA sequencing technologies to track clues in the brain for signs of autism. Researches know that genes play a role in autism and many different genetic and biological mechanisms are mostly likely to be involved. However, scientists have found some genetic mutations in an autistic child and is also found in a normal child and one with disorders. Recent findings show that the rare mutations link to genes in common biological pathways and networks-which help control the way the brain develops and functions. Some genes help with communication or growth of a cell. Scientists are conducting many labs and experiments to hopefully find a cure and explanation for autism.
ReplyDeleteThis relates to what we are learning because it talks about genetic mutations. I learned that mutations can have a great impact on a cell and lead to disorders. I thought this article was really interesting because my brother is autistic, and it would be really cool if scientists discovered a cure and an explanation for autism!

This article is explaining about children and autism and its a high chance that you get autism.When doctors know that a child has autism.They react different like they cant keep eye contact with a person to long or cant communicate,or speak at times and kinda just be in there own world at times. Its a disorder in the brain and does not let you do normal things and causes problems and happens most of the time. All these scientists are still trying to see what causes these disorders in children even in children without autism. This article just gives you the main point about autism and hopefully they find more things about these disorders that kids have. That it changes the way kids behave thats what i learned and what i think.
ReplyDeleteAutism is a disorder of neural development characterized by impaired social interaction and communication, and by restricted and repetitive behavior. Scientists are using new DNA sequencing technologies to find clues inside the brain and determine the causes of autism. The issue that scientists are encountering are that the mutations they are discovering in autistic children are occasionally also found in children without autism. They use DNA to examine the codons that cause autism. Scientists will continue on their quest to explain autism.
ReplyDeleteAutism is a spectrum of disorders that affect a person’s ability to communicate and interact with others. The disorders in the autistic spectrum include conditions with many symptoms that range in severity and combinations. Researchers are using genetics to try to figure out the cause of autism. However, they are finding in all of the many tests that are being conducted, that there are many different genes that could be causing the autism. But when the look at the DNA of people without autism, some of those genes are also found in the DNA of people with autism. So at this point, scientists have multiple genes that may or may not contribute to autism. Hopefully, they will be able to continue their research and find out what is causing autism.
ReplyDeleteAutism is a social disability for one to react with other. Scientist have found thousands of smaller dissorders that may contribute to autism. scientist have found that just over 1/100 kids are autistic. scietist are still investigating in to the details of Auism and hope to find more!
ReplyDeleteAutism is a "spectrum" of disorders. People with autism usually have a really hard time communicating and social interaction. The symptoms can range from mild to severe. The research/tests scientists are doing includes focusing on finding normal differences in a quantity of genes. Researchers found that a few genetic differences linked to autism and the increasing results were disappointingly small. After that, researchers began looking for rare variants in autism and found them. Researchers also are working to find even more subdued mutations. Scientists are working to recognize all the genes involved and create an index of autism risk genes. Other scientists are looking at differences in gene activity to find "biochemical markers" for premature diagnosis. Researchers have found dozens of genes over the past few years that appear to increase the risk of autism. Using practical MRI, the scientists look to see whether the brains of people with/without autism operates differently in particular sections during "language-related tasks".
ReplyDeleteAutism is a disorder that gives people a hard time with speaking and social interactions. Scientists have turned to new DNA sequencing technology methods to find the who,where, and hows of autism. To untangle all the complications, researchers are using the genetic findings as a start and then see the products of the genes work in the brain. Other laboratories are using new technologies to sequence all protein-coding regions and also are identifying a person’s DNA to find parts of the genome that are in people that have autism. In the end, researchers found the rare variants in autism that they were looking for.
ReplyDeleteThis artile talks about the genetic disorters called autism. Autism is not one disorter but many disorters in one. People with autism often have problems with social activities. Symptoms can be small or large, and about half of kids with autism have an intellectual disability. In the United States,one in 110 children has an autism disorder. Scientists stated that most of the reasons for autism comes from your genes. Scientists are still trying to solve how to find a cure for autism and they have found some reasons but some were more rare than others. Scientists are working hard for finding a cure and the reason why it happens. my uncle is autistic so if they found a cure it would be cool!
ReplyDeleteAutism is a disease that usually affects children and causes impairment in their speech and social skills. Scientists are doing many different tests/studies to see how and what is possibly tied in with autism. They have found many DNA mutations which they believe to be related to autism. However, the information is not truly proven as the mutations have appeared in non-autistic people - as well as other diseases like manic-depression. The scientists are using various methods and advanced DNA sequencing machines to find these mutations the believe are linked to autism. Yet there is still another problem: the scientists don't know what to do with the information. They have found the hundreds of mutations that they believe to be related to autism, but are unsure what is the best way to use those findings/further explore them. It is now a time to wait and see what they will decide.
ReplyDeleteAutism is a disorder marked by impaired social interaction and communication. Scientists are looking for mutations in genes, hoping to find a recognizable pattern in autism. Scientists want to find a way to treat autism at an early stage. So far, scientists have found out that variants of autistic genes had either duplicated DNA or missing DNA. Genetic changes were inherited from the parents or were new alterations of DNA in the egg or sperm of one of the parents or the baby itself. Now scientists believe autism is a collection of rare syndromes that affect the growth of the mind.
ReplyDeleteAutism is a disability/disorder, that makes interacting socially and communicating difficult. Researchers are looking into genetic information, to see how affected people's gene's work. While scientists are for indiviual point mutatuions. Scientists are hoping to find the right DNA genes that are supposed to fix the mutations.They have found that the younger the child is, the more flexible their brain is. Also, they found that several genes can come up with the chances of having Autism.
