Chromosome Abnormality Linked to Autism

A study published in the New England Journal of Medicine links an abnormality in Chromosome 16 to Autism. While the study found this evidence in a very small number of subjects, researchers claim this finding is evidence that our genes are one of the causes of Autism and could lead to the discovery of other genetic links as well. The specific defect is a deletion or duplication of a section of Chromosome 16. And not necessarily directly inherited from either parent - instead developed spontaneously sometime after conception. Possibly due to interplay of various genetic factors inherited from the parents, although having family history of Autism puts fetuses at higher risk of developing the defect. Doctors believe that approximately 90% of all cases of Autism are inherited. Researches claim a pre-natal test for the deletion is years away.

Even though we don't know of anyone with Austism in our family history, this study confirms my long-held belief that Jaden is a product of our family's DNA. Of course I admit, I've had that thought - "Could I have done something differently? Was there something I did/ate/didn't do when I was pregnant with Jaden that caused this?"....but I've always known in my heart that God created Jaden just the way he is. He's a true blessing, and I wouldn't change anything about him!!!

Do I think potentially autistic babies will be aborted? Probably not. If, as the study states, 90% of Autism is genetically linked, then those who face raising children with the abnormality are likely already dealing with it in themselves or other family members. Education is key - the earlier the diagnosis, the earlier the families can become educated about kids on the Autism spectrum & their needs - the better off our children's lives will be!

Autism is a quirk, not a death sentence. Let's keep it in perspective.
