These conditions and disabilities vary a lot, from mild to severe. Some mean that the pregnancy miscarries in its early stages.

What is the most common genetic birth defect?

If a baby is born with a part of the body that is missing or malformed, it is called a structural birth defect. Heart defects are the most common type of structural defect. Others include spina bifida, cleft palate, clubfoot, and congenital dislocated hip.

Can birth defects be seen on ultrasound?

Ultrasound can detect some types of physical birth defects. Examples of physical birth defects that may be found at 19 – 20 weeks are most cases of spina bifida, some serious heart defects, some kidney problems, absence of part of a limb and some cases of cleft palate.

What race has the most birth defects?

The risk of infant death from birth defects varied among racial/ethnic groups, but for all ethnic groups, the risk was higher than for white infants. American Indians had the highest rates of lethal birth defects, followed by Asians, Hispanics, and blacks.

What causes abnormalities in baby during pregnancy?

Birth defects can be caused by genetic factors and by a variety of environmental injuries such as infection, radiation, and drug exposure during pregnancy. The majority of birth defects, however, are without detectable cause. About 20% of birth defects are caused by genetic or hereditary factors.
