A married couple has two children at home who have been diagnosed with the same autosomal dominant condition. The nurse is interviewing the couple after they become pregnant with their third child.

Based on the nurse's understanding of related psychosocial issues, which statements by the mother may be expected?

Select all that apply.
1. I feel so guilty.
2. I feel like my daughter is angry with me because I am the one who has this bad gene in my body.
3. I am depressed and angry with myself.
4. My son has been smoking marijuana and skipping school.
5. I hope the new baby is a boy so he won't have the same illness.

Question 2

A fetus is found to have an autosomal recessive condition. After genetic testing is completed, both of the fetus' parents are found to have this same autosomal recessive genetic alteration.

Which statements made by a parent indicate that further education is required?

Select all that apply.
1. This condition is related to a genetic alteration of the X chromosome.
2. This condition is a Mendelian condition.
3. So, we are carriers of this condition because we don't have any signs of symptoms of this condition.
4. Our baby would have a better chance of living if we would have both been positive for an autosomal dominant condition.
5. The problem is the result of an alteration of just one single gene.

Answer to Question 1

Correct Answer: 1,2,3,4

The parents of a child with a genetically transmitted disease may feel guilty. Some children may feel angry toward the parent who carries the altered gene. The parent or parents may feel angry or depressed. A child with a late-onset disease may be more likely to engage in risky and less socially acceptable behaviors. Both males and females are equally affected with an autosomal dominant genetic disorder.

Answer to Question 2

Correct Answer: 1, 4

Genetic alterations of the X chromosome are referred to as X-linked recessive or X-linked dominant conditions. Autosomal recessive conditions are the result of an alteration of any of the 22 non-sex chromosomes. It is not necessarily true that the infant will die due to an autosomal recessive condition. The baby that is affected by a homozygous autosomal dominant condition is much more likely to die from problems associated with that type of condition. This is a Mendelian condition because it follows Mendel's laws of inheritance. The parents denied having any clinical manifestations associated with the condition so they are most likely carriers of the condition. These types of conditions are monogenic because they affect one single gene.
