Genetic testing of an asymptomatic woman whose sister is positive for the mutation that is responsible for an autosomal-dominant disorder that has a 70% penetrance rate would fall into which testing category?
a. diagnostic predisposition
b. predictive predisposition
c. diagnostic presymptomatic
d. predictive presymptomatic

Predictive predisposition.

Explanation:

Penetrance may be defined as the percentage of the mutations that are observable in the population. The genetic testing can be done to know the penetrance of the disease in family generation.

Predictive predisposition testing is done to analyze the penetrance. Asymptomatic means the predictive is used in the situation where the penetrance rate is being high and the individual can be pre disposed to the medical situation.

Thus, the correct answer is option (D).
