Study Notes
Reasons for Genetic Testing
- Family history of genetic disease: If a close relative has a genetic disorder, parents might want testing to see if they carry the gene. A couple carrying a recessive gene for a disease has a 1 in 4 chance of producing a child with the condition.
- Previous child with genetic disease: Parents who have a child with a serious genetic illness may wish to be tested for carrying recessive genes for the same condition.
- Recurring pregnancy loss: Two or more miscarriages or stillbirths can suggest chromosomal issues.
- Advanced maternal age: Women over 35 face an increased risk of having a child with Down syndrome, prompting possible genetic testing.
