Birth defects are estimated to affect more than 120,000 children in the United States every year. An infant may be born with a birth defect caused by a problem in his or her chromosomes, metabolism, formation of external body parts (such as limbs) or internal organs, or all three.
To better understand the impact of birth defects, the California Environmental Health Tracking Program (CEHTP) portal contains data and information to help track 12 different birth defects in California.
