Treatments for Chromosomal Abnormalities

There are no cures for chromosomal abnormalities but treatments are available to correct some of the conditions that result from them. For example, about half of babies born with Down syndrome have a heart defect. About 10% are born with intestinal malformations that require surgery, and more than 50% have some visual or hearing impairment. Treatments for many of these conditions allow a better quality of life. Most communities offer special education for mentally handicapped children.

Prenatal testing for chromosomal abnormalities can be helpful in managing the pregnancy for the best care, understanding and preparing for potential problems that the infant may have at birth, or offering the option to end the pregnancy if an abnormality is found.

Because most chromosomal abnormalities are not treatable, genetic counseling can offer guidance to couples who are carriers of chromosomal abnormalities. Once the risk of passing on an abnormality is assessed, the couple can then decide whether to continue to try to conceive using their own eggs and sperm, try using donor eggs or donor sperm, consider adoption, or remain childless.
