Slide 1-

Clinical Applications of Genetic Tests Mikenzie Lewis
Slide 2-

Types of Genetic Tests Diagnostic- establishes the basis of an existing disorder Predictive- determines the presence of genetic condition when there are no obvious symptoms Carrier- identifies heterozygotes Prenatal- assesses a fetus for abnormalities
Slide 3-

Diagnostic Testing Based on physical signs and symptoms Can be performed on any age Not available for all genes or genetic conditions
Slide 4-

Predictive Testing Helpful to those who have family history of a disorder but show no features of the disorder at time of testing Used often to detect cancers
Slide 5-

Carrier Testing Identifies heterozygotes for X-linked and autosomal recessive disorders that occur with high frequencies in certain populations Knowledge of carrier status gives couples the opportunity to make reproductive choices
Slide 6-

Prenatal Testing Performed during pregnancy to determine whether there is a significant risk of having a child with a serious disorder Counseling should precede a prenatal test
Slide 7-

Down Syndrome Detected by Prenatal Testing Accomplished with amniocentesis- an invasive procedure that involves taking amniotic from the mother and identifying fetal cells Can also be detected with ultrasound
Slide 8-

Test Results Can be difficult to interpret and explain Medical history, family history, and type of genetic test are important Positive Result= change found in a particular gene, chromosome, or protein Negative Result= no change found
