Study reveals possible genetic risk for fetal alcohol disorders
Date:9/21/2007

and stress responsiveness in infants can themselves lead to problems, she says.

"If a baby is very irritable and stress reactive, one of the things this can interfere with is the caregiver-infant interaction," she says. "In real life, negative events tend to cluster. So if there's alcohol in the environment, there may also be stress. And then if you have an irritable baby, this all could have cascading effects on the child's psychological development."

Recognizing that complex behaviors are seldom, if ever, governed by a single gene, Schneider and her colleagues are also investigating other gene alleles for their potential to interact with fetal-alcohol exposure and put children at risk.

"Genetics by themselves rarely tell us much, because life experiences may trigger the actual effects of our genetic vulnerabilities," says Schneider. "So the more knowledge we have about the ways that genes interact with environmental factors, the more we can envision interventions early in life to help a vulnerable child."
