List of Birth Defects

Results from our 2015 Registry report provides data on the most frequently reported birth defects.  This lists the structural and functional birth defects reported to the registry by frequency. Of course, the functional problems far outnumber the structural birth defects.

Since October of 2015, parents have completed 3983 questionnaires with case reports for 4529 children (more than one child in a family can be reported on a questionnaire) in the on-­‐line National Birth Defect Registry. We have reports for 2372 males, 2144 females and 13 cases where the sex was not entered.
