Cystic Fibrosis in Children: Comprehensive Nursing Notes ( 12 Questions)
The parent asks, "How is CF inherited?" Which of the following statements by the nurse is correct?
CF is not inherited through an X-linked dominant pattern. X-linked inheritance involves genes located on the X chromosome, and CF is not linked to this type of inheritance.
No explanation
CF is not solely related to inheriting a defective CFTR gene from one parent. While inheriting a mutated CFTR gene is a factor, CF is an autosomal recessive disorder, meaning it requires mutations in both copies of the CFTR gene (one from each parent) for the disease to manifest.
CF is not solely caused by the deletion of phenylalanine at position 508 (F508del). While this mutation is one of the most common causes of CF, it is not the only genetic variation associated with the disease. CF can result from various mutations in the CFTR gene.
"CF is an autosomal recessive genetic disorder.”.
Choice A rationale:
CF is not inherited through an X-linked dominant pattern.
X-linked inheritance involves genes located on the X chromosome, and CF is not linked to this type of inheritance.
Choice C rationale:
CF is not solely related to inheriting a defective CFTR gene from one parent.
While inheriting a mutated CFTR gene is a factor, CF is an autosomal recessive disorder, meaning it requires mutations in both copies of the CFTR gene (one from each parent) for the disease to manifest.
Choice D rationale:
CF is not solely caused by the deletion of phenylalanine at position 508 (F508del).
While this mutation is one of the most common causes of CF, it is not the only genetic variation associated with the disease.
CF can result from various mutations in the CFTR gene.
