Course Content # 17

• Explain the important role of genetic counseling.

Page 3: P020A Developmental Disabilities Lecture #3

Genetic Counseling

• Issues related to inherited disorders

Page 4: P020A Developmental Disabilities Lecture #3

Prenatal testing

• Ultrasound sonography– Sound waves images– Detect structural

abnormalities

Page 5: P020A Developmental Disabilities Lecture #3

abnormalities

Page 7: P020A Developmental Disabilities Lecture #3

Screening for future problems

• DNA – based genetic tests

Angelina Jolie fallout: Should counseling be required with DNA

screenings?Jon Entine | May 28, 2013 | Genetic Literacy Project

• The decision by Angelina Jolie to undergo a double mastectomy after tests determined she carried a genetic mutation that elevated her chances of developing breast or ovarian cancer has led to renewed calls for expanded genetic screening. It has also raised a disconcerting question—could genetic testing actually be harmful to your health?
