How far does the genetic apple fall from the tree?

Inevitably, once your child is diagnosed with an ASD, the question will arise as to whose got the faulty family tree.  In our case, we know both trees to be rotten.  Really!  There is sufficient evidence that indicates a genetic component to Asperger Syndrome.  I am not sure that either one of us would be clinically diagnosed as having an ASD, but between us we have a preponderance of traits.  As I mentioned earlier, my husband has a huge problem with forming and maintaining relationships.  We have had many discussions about this throughout our marriage.  Even though he has reiterated that he does not feel the need for friendships because he has enough interests to make up for the lack of social interaction (he loves to jog and is a wine enthusiast) he does occasionally complain that he feels isolated.  He tells me that he "has always had a feeling of not fitting in anywhere."  As for myself, I have struggled with anxiety my entire life and have had several episodes of panic attacks.  I also suffer an occasional bout of depression which typically last several months.  I have a huge problem with change in my life and I have hypersensitivity to sound.  Tristan's doctor was particularly interested in the panic attacks.  I am not sure why that is the case. 

My good friend tells me that "we all have our issues" and I couldn't agree more.  Most people I know do have their own set of issues.  I guess it really does not matter why our son has AS although you can't help but wonder.  I wonder if taking my prenatal vitamins would have made a difference.  I couldn’t take them because I would vomit immediately.  I wonder if it was the medication my doctor prescribed for morning sickness.  I guess we will never fully understand the why.  I do know that I love him just the way he is.
