Autism Gene Found

Post Reply New Topic

More than one gene has to be responsible. If Neurotypical was dominant:



N n

N NN Nn
N Nn Nn - this couple wouldn't be able to have Autistic children.


N n
N NN Nn

n Nn nn - this couple would get roughly a quarter of their children being autistic, in theory.



N n

n Nn nn

n Nn nn - this would produce an even spilt.



n n

n nn nn
n nn nn - it would mean that autistics can't produce Nt kids but it happens.


Ignoring the overwhelming majority of NTs if autism was domiant it would look like this:


Homozogous autistic parent x Hoap.


A A
A AA AA
A AA AA - autistics can't produce nts but we know it happens.



Hoap x Heap

A a

A AA Aa
A AA Aa - not producing nt kids.


Heap x Heap.


A a

A AA Aa
a Aa Aa - so about half of their children should be nt.


A A
a Aa Aa
a Aa Aa with this genotype, all the kids'd have to be autistic.


a a
a aa aa
a aa aa so Nt + Nt would have to equal NT but that doesn't always work.


Also, given that the majority of diagnosed aspies are males, if we take that as a fact - then I submit the genes responsible for Autism - or at least one of them - are X-linked.

I think the main benefit of the new genetic research is fore knowledge. If you know that you are pregnant with an autistic child then you can spend [6 months?] reading up and educating yourself about what to expect.

I hope it won't alter people's ultimate decision, afterall I was warned that one of my boys might be deaf - they couldn't tell me in advance to what degree of deafness and only statistical.

I read all I could about the subject - now if they'd told me that he was going to be autistic I'd have been in a different section of the library.
