Say a prayer for Jonathan !!!
Hi
The University of Washington Autism center just put out a new research paper that says the chances are 1 in 20 that you will have another child with Autism. You can go onto their autism website and get all the new research data at: http://depts.washington.edu/uwautism/
Hope this helps
1 in 20 amounts to 5%.... the studies I have read are 5% - 10%..... However I dont think any can completely agree....

| Genetic Factors |
At least 16 of every 10,000 babies is born with autism or one of its related disorders. Since autism was first identified in 1943, scientists have made great strides in describing its symptoms. The biological basis for autism, however, has been elusive -- an unfortunate circumstance, because such an understanding could enable researchers to identify the leading risk factors for autism and possibly to design new treatments for the condition.
By examining the inheritance of the disorder, researchers have shown that autism runs in families, thought not in a clear-cut way. Siblings of people with autism have a 3 to 8 percent chance of being diagnosed with the same disorder. This is much greater than the 0.16 percent risk in the general population but much less than the 50 percent chance that would characterize a genetic disease caused by a single dominant mutation (in which one faulty gene inherited from one parent is sufficient to cause the disorder) or the 25 percent chance that would characterize a single recessive mutation (in which a copy of the faulty gene must be inherited from each parent). The results fit best with models in which variants of several genes contribute to the outcome. To complicate matters further relatives of people with autism may fail to meet all the criteria for the disorder but still have some of its symptoms.

Furthering suspicion of autism’s genetic origins is its occurrence among siblings. Parents of autistic children have a 6 percent chance of giving birth to another child with autism. Fraternal twins have a 10 percent chance of sharing autism, and identical twins share a 90 percent chance of autistic concordance.

Genetics plays an important role. Overall, about 1 child in 500 has autism or a closely related disorder. However, within a particular family, if one child has autism, the chances of a second child having the disorder are dramatically increased, to about 10 to 20 percent.
On average, biological siblings have about half their genes in common. This is also true of non-identical twins. Identical twins, on the other hand, share all their genes. In identical twins, if one has autism, there is a 60 to 70 percent chance that the other will, too.
If genes told the whole story, of course, 100 percent of these identical twins also would have autism. The fact that there are some identical twin pairs in which one has autism and the other doesn't means that there must be other causes. In many cases, however, these causes are unknown.

Who usually gets autism?
Current figures show that autism occurs in all racial, ethnic and social groups. These statistics also show that boys are three-to-four times more likely to be affected by autism than girls are. In addition, if a family has one child with autism, there is a 5 to10 percent chance that the family will have another child with autism. In contrast, if a family does not have a child with autism, there is only a 0.1 to 0.2 percent chance that the family will have a child with autism.

For a couple with one autistic child, the chance of having a second child with autism is estimated at around 5% to 10%: "Genes play a role in the cause of autism. If a family has one child with autism, their chance of having a second child with autism is 1 in 20, approximately 50-100 times more likely than the general population." University of Washington Autism Center http://depts.washington.edu/uwautism/giving/ "Scientists estimate that, in families with one autistic child, the risk of having a second child with the disorder is approximately five percent, or one in 20, which is greater than the risk for the general population." National Institutes of Health Autism Fact Sheet http://people.sca.uqam.ca/~sqa/nih_fact.html "When parents have one autistic child, they have a higher risk of having a second child with the disorder - a 5 percent to 10 percent chance versus the 0.1 percent to 0.2 percent chance for unaffected families." Vaccination News http://www.vaccinationnews.com/DailyNews/January2002/FEATDai lyNewsletter1-06-02b.htm "Scientists have known for some time that autism often runs in families. Studies suggest that if one child is autistic, there's a 5% to 10% chance that any sibling will be autistic, and a 30% to 40% chance that the sibling will have milder, but related, problems."

::: warning long:::
I don't know the odds on another spectrum child but I have been told that my daughters epilepsy and son's autism goes hand in hand with a lot of families. You might want to do some research in this area also. Epilepsy can be just as debilitating and even harder to deal with at times than autism.
My oldest is NT Amberly, Libby is my epileptic who started having seizures at 4 months of age. She's been on several medications, ton's of testing. Hurt herself during seizures and had to have stitiches in her face. I won't let her spend the night at other houses unless they know what to do for her seizures. Medication daily from age 1. Pills, pills and more pills. Neuro visits every 3-6 mo. depending on how often she is seizing. Blood work every visit for medication levels. Drs. calls in between visits for medication changes, I am over protective of her in some ways that I am not with Zach. This year she will be riding her bike to school by herself. I'm scared to death! She has always had her sister with her. School is very scarry for her and me. In preschool she seized several times and it scared the other kids. One time wetting on a para pro (who didn't follow directions and take her to the bathroom after the seizure) In kindergarden she seized and fell and busted out all of her front teeth out and damaged others that had to be pulled. She has memory issues and loss.
Then I had Zachary, his list has been just as bad. Heart condition, hypoplastic, rt. ventricle large, lft. ventricle small, ear infections from birth, pink diaper syndrome, jaundice, brain bleed, tubes in ears at 4 mo., chordee-surgically fixed with a skin graft, hearing loss, autism, severe speech delay, comprehension at 9-12 mo., sensory probs., and now he has shortened heal cords from toe walking which PT will start next mo. for. He runs away from home without a care, very un emotional, climbs like a monkey, can't ride a bike or peddle at all, but can run my computer better than I can and play video games adults can't play!
My list is long and I havn't even gone into dh's and my health that's a whole other story LOL.... My hands are full but so is my heart! I wouldn't trade or swap or give away any of my kids for anything they are mine and I love them beyond life itself. If you are unsure of bringing a child into this world who might have a disability then you don't have another child. It's not like buying a car, life gives you a precious child to love no matter what. Would you love another child less for a disability? I worried about another epileptic child but got a wonderful little boy who has health problems in a whole different way. I may biotch and whine and moan because I am having a bad day and am unsure how to cope. But that's a reality of life. I'm not a perfect mother and don't always know what to do.
Ultimately the choice is yours, make it wisely and don't whine about what you are given. I have been given great gift's and am close to all my children for who they are not what they are. I look beyond the "dis" abilities and look at all their ablities. Libby this year ran 5 miles! Zach 2 miles! My oldest is on the honor roll, and learned how to swim and dive this year. Libby is starting ballet this year (again lol we tried when she was 3 and that was just too young) Zach is finishing a parent tot swim class tonight which he has loved. I scrapbook all their accomplishment and even their boo boo's. Life is all about the experiences.
Ok if I remember correcly from what I read, it's 5-10% increase in chance w/ siblings? Someone correct me if I'm wrong I haven't looked that up in awhile.
Amber
That's what I heard too Amber...although if your child has the gene...I think I read it's a 50-100% chance. Broad range I know! I don't think there's anything definitive there though...still researching that?Hi everyone! Well i had a question! Does anyone know what the chances are that after you have one child on the spectrum that any child born with of the same two parents will be on the spectrum?? I looked around tonight a little but i havent found anythin useful! Id appricate any information on it! I plan on requesting the blood work for the single gene answer to see if our daughter has it! Has anyone else had that blood work done?
