Scientists warn of chemical-autism link
...Studies have strongly suggested a genetic component in the cause of autism, but it's becoming clear that genetics alone isn't the whole story; there could be interactions between susceptibility genes and environmental chemicals.
Recent research from her group, appearing in the journal Epidemiology, showed that prenatal vitamins taken prior to conception seem to interact with certain metabolizing genes that are inherited. Those women who did not take the vitamins, and had the high-risk genotypes, were more likely to have a child with autism. Still, this was a small study limited in scope, and more research should be done to confirm these findings.
The central nervous system of the fetus is sensitive to a wide range of chemicals, Hertz-Piccotto said. Hormones, such as estrogens and androgens, are essential for proper brain development. Endocrine-disrupting compounds need more research, she said. Flame-retardant chemicals called PBDEs interfere with the body's hormones. Even though many of them are no longer used in manufacturing, they can hang around in the environment and the human body for a long time. The Environmental Protection Agency (EPA) is aware of concerns about these chemicals and is working on accessing substitutions (see the action plan)....
