Pregnancy is a boon in a woman’s life. However, no mother in this world can digest the fact that her baby was born with a genetic disorder. The irony is that there are various kinds of genetic disorders that occur at the time of birth or during pregnancy. These disorders can be due to either a single gene mutation or might because of chromosomal abnormality
One important reason or risk factor that has been cited by scientists as the cause of congenital genetic disorders is age-related pregnancy. According to a study, the baseline population risk for all couples of having an infant with a major genetic disorder is 2-5 percent. However, in case of mothers who are more than 35 years of age at the time of delivery have an increased risk of giving birth to infants carrying a chromosomal abnormality. One good example is the Down syndrome. This is because, these mothers are considered to come under the advanced maternal age group where there are higher complications related to child growth during pregnancy. These women are also likely to have some pre-existing disorders that get transferred to the child. Similarly, in case, the age of the father is above 40 years at the time of delivery, there is a higher risk of infants developing disorders such as Marfan syndrome, achondroplasia and Apert syndrome.
Teenagers form another age group that is at increased risk of giving birth to infants with congenital disorders. In fact, teenage mothers account of 13 percent of all pregnancies in the U.S. Due to lack of knowledge and proper guidance, teenage mothers usually tend to neglect prenatal care, a factor that can be really detrimental to the development of the fetus resulting in genetic abnormalities.
