Study Notes
Causes and Risk Factors for Birth Defects
- Known causes of birth defects include genetic factors, environmental exposures, maternal conditions, and teratogenic drugs.
- Specific maternal conditions such as diabetes, obesity, and infections during pregnancy can elevate the risk of birth defects.
Chromosomal and Single Gene Defects
- Approximately 20-25% of birth defects are attributed to chromosomal abnormalities or single gene defects.
Maternal Conditions Impacting Birth Defects
- Conditions like uncontrolled diabetes, advanced maternal age, and exposure to certain infections (like rubella or Zika virus) during pregnancy pose increased risk for birth defects.
Genetic Syndromes and Heart Defects
- Down syndrome is notably associated with a heightened incidence of congenital heart defects in infants.
Common Causes of Birth Defects
- The most common cause of birth defects are genetic anomalies, which include both chromosomal and single gene defects, alongside environmental influences.
