What's more, researchers have a pretty good handle on what this gene does. It plays a role in calcium metabolism at the cellular level. This offers the promise of identifying the fundamental mechanisms of autism, which thus far have been elusive.
I trust you've noticed that “genesis” and “genetics” have a common root -- gen -- which means to create. Our chromosomes are not so much a blueprint of our bodies, but a recipe book: The steps involved in building a particular body with its various strengths and vulnerabilities are written there. Much is determined -- for good or for ill -- by aspects of the particular kitchen in which that recipe is followed, or in other words, by the environment in which genes convey their messages. Often, that environment is my focus. But today, it is the genes themselves -- because they do, indeed, matter.
Unfortunately, there is no immediate practical application of the new research. But while the timeline can at times be frustratingly protracted, knowledge, ultimately, is power. Every parent dealing with or concerned about the challenges of autism should be encouraged that our knowledge is clearly advancing. As we get to the genetic origins of autism, we get closer to effective treatment, or cure, or perhaps, ultimately, consistent prevention.
We have a ways to go -- but on behalf of us all, thanks to these researchers who have clearly moved us along in the right direction.
