would be to contact a major autism research group, such as the Transcend Center at Harvard/Mass General.
Unfortunately, I don't think there's a one-size-fits-all answer -- the research seems to be showing a multitude of causes/contributers to autism, interacting with the child's own physiology.
Here is a link to the Harvard/Mass General center. It lists other centers across the country.

Mission
TRANSCEND’s mission is to improve outcomes in autism and other neurodevelopmental disorders (NDDs) by using sophisticated and coordinated objective measures to characterize what can be changed in these conditions.
By looking at brain problems at several integrated levels and in a whole body systems context, we aim to maximize understanding and maximize our ability to find ways to help.
By applying cutting-edge science, measurement technologies and informatics to treatment research and clinical-behavioral practice, TRANSCEND aims to minimize suffering, optimize quality of life for individuals and families, and maximize chances for individuals to reach their full potential - now.
Unique, Whole Body Approach
TRANSCEND’s partners work from a model of autism that describes a complex whole body condition with many treatable facets.
Brain as part of the body
We look at the brain not just as an information-processing computer but also as a physical organ that is part of the body.
We think that the way the brain processes sensory, emotional and social information is related to the health of the cells of the brain, which can be related to the health of cells in the body.
We think that changes in the way the brain processes sensory, emotional and social information might come from physical changes in the cells of the brain related to some kinds of physical illness in the body (especially immune problems), and not just from the brain developing differently before a baby is born.
Brain and body problems in autism and other neurodevelopmental disorders and how they develop
We suspect that the relationship of health problems and brain/behavior problems may develop in close relationship to each other.
Therefore we look at how brain and body problems develop early in autism and how these brain and body problems may relate to each other early on
