A baby is born with a genetic disorder. Neither parent has a history of this disorder. The nurse realizes that the cause of this disorder can be explained as being:

1. De novo.
2. Penetrance.
3. An X-linked dominant condition.
4. Evidence to justify the need for a paternity test.


De novo.

Rationale: When there is no previous history of a condition in any other immediate or distant family member, including even subtle signs and symptoms of the disease, the disease may be caused by a spontaneous new mutation. This is called "de novo." Penetrance is the probability that a gene will be expressed phenotypically. X-linked conditions are recessive in nature. The need for a paternity test is not influenced by genetic conditions.
