A couple wants to start a family. They are concerned that their child will be at risk for cystic fibrosis because they each have a cousin with cystic fibrosis. They are seeing a nurse practitioner for preconceptual counseling
What would the nurse practitioner tell them about cystic fibrosis?
A) It is an autosomal dominant disorder.
B) It is passed by mitochondrial inheritance.
C) It is an X-linked inherited disorder.
D) It is an autosomal recessive disorder.
Ans: D
Feedback: Cystic fibrosis is autosomal recessive. Nurses also consider other issues when assessing the risk for genetic conditions in couples and families. For example, when obtaining a preconception or prenatal family history, the nurse asks if the prospective parents have common ancestors. This is important to know because people who are related have more genes in common than those who are unrelated, thus increasing their chance for having children with autosomal recessive inherited condition such as cystic fibrosis. Mitochondrial inheritance occurs with defects in energy conversion and affects the nervous system, kidney, muscle, and liver. X-linked inheritance, which has been inherited from a mutant allele of the mother, affects males. Autosomal dominant is an X-linked dominant genetic disease.
