New Genetic Link Tied to Autism

One of our biggest worry as parents is “WHY” our children have fallen on the spectrum. What caused something to happen to our child? Was it genetics, vaccinations, or could it have been something environmental?

Well, scientists at UCLA have recently published their findings that links a specific genetic variant to the disorder. The test focused on the speech delay of children, as the most common early symptom Autism is the lack of speech.

UCLA scientists have used language onset the age when a child speaks his first word as a tool for identifying a new gene linked to autism. The team also discovered that the gene is most active in brain regions involved with language and thought. Interestingly, evidence for the genetic link came from the DNA of families with autistic boys, not those with autistic girls.

Their findings have suggested that this gene, called contactin-associated protein-like 2 (CNTNAP2), likely plays a “key role in the development of autism.” They also found that the gene was most prevalent in families with autistic boys.

“Autism strikes boys three times as often as girls,” said Maricela Alarcon, first author and UCLA assistant professor in residence of neurology. “This finding may partly explain why.”

I’m very excited by this research, and will be following it closely. I highly suggest that you read through the entire article, which was written by UCLA Health Services.
