Abstract
All the known or conjectured environmental causes of congenital malformations in human beings consist of positive factors, chemical, infectious, etc. (Kalter and Warkany 1983) – with two exceptions. The only two instances of malformations being attributed to negative conditions are deficiency of iodine, described earlier in this work, and deficiency of the vitamin folic acid. The latter, a major subject, is told here.
