It is my job in society to prevent young and innocent lives from being lost and destroyed.  I have volunteered and worked for several different afterschool programs, helping agencies, and day camps.  I now have and internship with child services in my home state, and even though so far it&amp;#39;s been emotionally hardcore, I have no intentions of turning back.  &lt;br /&gt;My point is there may be some genetics involved in this disorder, but I really believe that people with Asperger syndrome and other forms of autism on the high functioning end can do things that many people believe they can&amp;#39;t or deliberately don&amp;#39;t do.  Don&amp;#39;t get me wrong, my own family, as well as many close others were shaming me into going back to the science field, and it made me feel very useless, but I simply refused to go back.  Their resistance and my own deficits together were just no match for my passion.  &lt;br /&gt;&lt;br /&gt;I&amp;#39;m not advising those out there to enter this field or not enter it, but if you feel passionate about a cause of some kind, there has got to be a way.</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/4499632980008833398'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/4499632980008833398'/><link rel='alternate' type='text/html' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html?showComment=1255366493869#c4499632980008833398' title=''/><author><name>simba222</name><email>noreply@blogger.com</email></author><thr:in-reply-to xmlns:thr='http://purl.org/syndication/thread/1.0' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html' ref='tag:blogger.com,1999:blog-22861867.post-1241849132747627477' source='http://www.blogger.com/feeds/22861867/posts/default/1241849132747627477' type='text/html'/></entry><entry><id>tag:blogger.com,1999:blog-22861867.post-8663722693862650994</id><published>2009-09-22T13:21:49.051-07:00</published><updated>2009-09-22T13:21:49.051-07:00</updated><title type='text'>Joseph,

It is not just a Mendelian trait with only two or three phenotypes. The reason it comes in such a broad spectrum is because it is polygenic, like height or skin color. Polygenic traits can be influenced by the environment as well. The argument against autism being genetic is the fact that sometimes only one identical twin develops it. It is the same principle as if one twin grows taller than the other, because he drinks milk while the other drinks soda. Whether one may develop autism or not is probably more complicated. It might not necessarily be triggered by chemical intake (from food or vaccines).&lt;br /&gt;&lt;br /&gt;BigTimeSynesthete</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/387602113602597551'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/387602113602597551'/><link rel='alternate' type='text/html' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html?showComment=1249333384787#c387602113602597551' title=''/><author><name>Anonymous</name><email>noreply@blogger.com</email></author><thr:in-reply-to xmlns:thr='http://purl.org/syndication/thread/1.0' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html' ref='tag:blogger.com,1999:blog-22861867.post-1241849132747627477' source='http://www.blogger.com/feeds/22861867/posts/default/1241849132747627477' type='text/html'/></entry><entry><id>tag:blogger.com,1999:blog-22861867.post-2599677539961163035</id><published>2009-07-29T03:48:38.676-07:00</published><updated>2009-07-29T03:48:38.676-07:00</updated><title type='text'>A very interesting blog and discussion.

The output is a non-linear function of the inputs.  &lt;br /&gt;&lt;br /&gt;There likely would be a statistical correlation between the genotype and the phenotype, but the environment can change that correlation in ways that are completely unpredictable from the genome.  &lt;br /&gt;&lt;br /&gt;We know that there are monozygous twins that are discordant for ASDs.  That is proof that there can be no precise diagnosis of autism from genes alone.  &lt;br /&gt;&lt;br /&gt;It is like the weather, why can't the weather be predicted months in advance?  It can't be because the parameters that are involved are non-linear and coupled.  The weather is inherently chaotic.  The weather is pretty simple, the fluid flow is understood, so is the heat and mass transfer.  The weather can’t be predicted because the coupling is non-linear.  Development is inherently chaotic too.  There are simply too many details to make deterministic predictions.  &lt;br /&gt;&lt;br /&gt;What the curebies want for autism is a test with a very low false negative rate.  Liability will force the providers of any such test to ensure that the number of false negatives is very low because the liability associated with a false negative will be high.  The only way you can decrease the false negative rate is by increasing the false positive rate.  If you call every test positive, there are no false negatives and no liability to support an ASD individual their entire life.  If we (arbitrarily) assign a cost of $1 million to each false negative and charge $1000 for each test, then there can be no more than 1 false negative per 1000 tests.</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/5489560642409285603'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/5489560642409285603'/><link rel='alternate' type='text/html' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html?showComment=1243978437154#c5489560642409285603' title=''/><author><name>daedalus2u</name><uri>http://www.blogger.com/profile/10416564922288784455</uri><email>noreply@blogger.com</email></author><thr:in-reply-to xmlns:thr='http://purl.org/syndication/thread/1.0' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html' ref='tag:blogger.com,1999:blog-22861867.post-1241849132747627477' source='http://www.blogger.com/feeds/22861867/posts/default/1241849132747627477' type='text/html'/></entry><entry><id>tag:blogger.com,1999:blog-22861867.post-6275797191395268316</id><published>2009-06-01T15:59:40.030-07:00</published><updated>2009-06-01T15:59:40.030-07:00</updated><title type='text'>I'm sure there's no gene for tallness, but if tall...</title><content type='html'>I'm sure there's no gene for tallness, but if tallness is highly heritable, I'm saying it should be possible to find a function f such that&lt;br /&gt;&lt;br /&gt;height ≈ f(genome)&lt;br /&gt;&lt;br /&gt;Or, in statistical terms, the association between observed height (at some age) and f(genome) should have a high correlation coefficient. &lt;br /&gt;&lt;br /&gt;If such a function cannot be found, it's simply because of computational complexity. &lt;br /&gt;&lt;br /&gt;Unless the heritability of height is explained by something other than DNA, I don't see how this could be incorrect.</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/6275797191395268316'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/6275797191395268316'/><link rel='alternate' type='text/html' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html?showComment=1243897180030#c6275797191395268316' title=''/><author><name>Joseph</name><uri>http://www.blogger.com/profile/11536734331366279894</uri><email>noreply@blogger.com</email><gd:extendedProperty xmlns:gd='http://schemas.google.com/g/2005' name='OpenSocialUserId' value='17264418446409199802'/></author><thr:in-reply-to xmlns:thr='http://purl.org/syndication/thread/1.0' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html' ref='tag:blogger.com,1999:blog-22861867.post-1241849132747627477' source='http://www.blogger.com/feeds/22861867/posts/default/1241849132747627477' type='text/html'/></entry><entry><id>tag:blogger.com,1999:blog-22861867.post-6155065143681380478</id><published>2009-06-01T15:03:38.217-07:00</published><updated>2009-06-01T15:03:38.217-07:00</updated><title type='text'>I fundamentally disagree.

You can't have a genetic test for "tallness" because everyone has the property of height, they are just on a spectrum.  &lt;br /&gt;&lt;br /&gt;Tallness is highly heritable.  Tallness does run in families.  If you did try to eliminate "tallness" from the human genome, you would be unsuccessful because having a height is an inherent property of being a human. &lt;br /&gt;&lt;br /&gt;Dogs have been bred to accentuate different properties of "dogness", but all dogs have a height, even though some breeds are very different than others.  Height is a property of a phenotype, not a genotype.  So is autism.  &lt;br /&gt;&lt;br /&gt;If you had 100 clones of an individual, they would have 100 different positions along the autism spectrum, just as they would have 100 different heights.  Some of those heights might be very similar, but none would be identical.  The more diverse the conditions during development, the more diverse the different phenotypes would be.  &lt;br /&gt;&lt;br /&gt;Development is a consequence of hundreds of thousands of non-linear coupled parameters.  The result (the phenotype) is fundamentally a result of chaos (in a mathematical sense).  It is fundamentally unpredictable.</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/6155065143681380478'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/6155065143681380478'/><link rel='alternate' type='text/html' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html?showComment=1243893818217#c6155065143681380478' title=''/><author><name>daedalus2u</name><uri>http://www.blogger.com/profile/10416564922288784455</uri><email>noreply@blogger.com</email></author><thr:in-reply-to xmlns:thr='http://purl.org/syndication/thread/1.0' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html' ref='tag:blogger.com,1999:blog-22861867.post-1241849132747627477' source='http://www.blogger.com/feeds/22861867/posts/default/1241849132747627477' type='text/html'/></entry><entry><id>tag:blogger.com,1999:blog-22861867.post-1941456849805597644</id><published>2009-05-28T14:46:14.883-07:00</published><updated>2009-05-28T14:46:14.883-07:00</updated><title type='text'>There's probably no genotype that exactly matches ...</title><content type='html'>There&amp;#39;s probably no genotype that exactly matches what we call autism.

Autism is a property of a phenotype, not a genotype.  &lt;br /&gt;&lt;br /&gt;Just like body size is a property of a phenotype.  There are genetic components to body size, but any individual can have a small body phenotype depending on the environment they developed in.  You can't make assumptions about body size from a genotype unless you make assumptions about development conditions.  &lt;br /&gt;&lt;br /&gt;I see ASDs as similar, but a lot more complex.  Many of the development conditions that are important are in utero and completely opaque and unavailable for measurement or analysis.</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/6133573277785492449'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/22861867/1241849132747627477/comments/default/6133573277785492449'/><link rel='alternate' type='text/html' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html?showComment=1243546585721#c6133573277785492449' title=''/><author><name>daedalus2u</name><uri>http://www.blogger.com/profile/10416564922288784455</uri><email>noreply@blogger.com</email></author><thr:in-reply-to xmlns:thr='http://purl.org/syndication/thread/1.0' href='http://autismnaturalvariation.blogspot.com/2009/05/why-is-it-so-difficult-to-find-autism.html' ref='tag:blogger.com,1999:blog-22861867.post-1241849132747627477' source='http://www.blogger.com/feeds/22861867/posts/default/1241849132747627477' type='text/html'/></entry><entry><id>tag:blogger.com,1999:blog-22861867.post-4686309171985773570</id><published>2009-05-20T23:52:08.846-07:00</published><updated>2009-05-20T23:52:08.846-07:00</updated><title type='text'>Autism, Dyslexia, Attention Deficit Disorder are a...</title><content type='html'>Autism, Dyslexia, Attention Deficit Disorder are all potential pitfalls when a child doesn't have proper &lt;A HREF="http://www.mmpp.com.sg/child-development.html" REL="nofollow"&gt; child development&lt;/A&gt;.
