Abstract
The practice of genetic counseling for neural tube defects (NTD) has changed substantially over the past 15 years with the advent of three major developments, i.e., second-trimester prenatal diagnosis, mass screening of pregnant women for elevated serum α-fetoprotein levels, and vitamin supplementation around the time of conception. On the other hand, the principles on which recurrence risk estimates are based have changed little, the multifactorial model of inheritance being the one that still fits best the epidemiologic data.
