CDC estimates that birth defects occur in about 1 in every 33 infants born in the United States each year. Birth defects can occur during any pregnancy, but some factors increase the risk for birth defects.
Q. What are some common birth defects?
- Anophthalmia / Microphthalmia.
- Anotia / Microtia.
- Cleft Lip / Cleft Palate.
- Congenital Heart Defects. Atrial Septal Defect. Atrioventricular Septal Defect. Coarctation of the Aorta. D-Transposition of the Great Arteries.
- Craniosynostosis.
- Diaphragmatic Hernia.
- Down Syndrome. Data and Statistics. Growth Charts.
- Esophageal Atresia.
Q. What can cause anomalies in an infant?
Approximately 50% of congenital anomalies cannot be linked to a specific cause. However, known causes include single gene defects, chromosomal disorders, multifactorial inheritance, environmental teratogens and micronutrient deficiencies. Genetic causes can be traced to inherited genes or from mutations.

Q. What are congenital abnormalities?
Congenital anomalies comprise a wide range of abnormalities of body structure or function that are present at birth and are of prenatal origin. For efficiency and practicality, the focus is commonly on major structural anomalies.
Q. What are the most common congenital anomalies?
The most common, severe congenital anomalies are heart defects, neural tube defects and Down syndrome. Although congenital anomalies may be the result of one or more genetic, infectious, nutritional or environmental factors, it is often difficult to identify the exact causes.
Minor anomalies are unusual external physical features which do not inhibit a major function of the body. Most of the normal population has one or two minor anomalies inherited from a parent.
Q. What are the chances of having a baby with abnormalities?
Q. What are some anomalies?
The most common, severe congenital anomalies are heart defects, neural tube defects and Down syndrome. Although congenital anomalies may be the result of one or more genetic, infectious, nutritional or environmental factors, it is often difficult to identify the exact causes. Some congenital anomalies can be prevented.
Q. What are the symptoms of chromosomal anomalies in children?
Pallister Killian syndrome – duplication of the 12th chromosome, resulting in intellectual disabilities, seizures and poor muscle tone (hypotonia). What are the signs and symptoms of Pediatric Chromosomal Anomalies?
Q. Which is an example of a structural anomalies?
Structural abnormalities include missing sections or duplications of chromosomes. Transfers (translocations) occur when sections move to another chromosome. Inversions occur when a chromosome breaks off and reattaches upside down. Rings will form when a chromosome section breaks off and forms a separate circle with or without the loss of material.
Q. What kind of chromosomal anomalies occur in males?
Klinefelter’s syndrome or XXY – occurs when there is an additional X chromosome in males, which impacts the testosterone hormone. Turner syndrome – occurs when there is a single X chromosome in females, which impacts the estrogen hormone. Structural abnormalities include missing sections or duplications of chromosomes.
