The initial signs of fetal alcohol syndrome are slight but classic: facial malformations such as a flat and high upper lip, small eye openings and a short nose.
Researchers want to know if those facial clues can help them figure out how much alcohol it takes during what point in development to cause these and other lifelong problems.
They have good evidence that just a few glasses of wine over an hour in the first few weeks of fetal life, typically before a woman knows she's pregnant, increases cell death. Too few cells are then left to properly form the face and possibly the brain and spinal cord.
