Summary nr 507 discussion part 1 week 2.What is the etiology of cystic fibrosis? Cystic fibrosis (CF) is an autosomal recessive inherited disease disorder. It is due to a mutated gene located in chrom... osome 7 (McCance, Huether, Brashers, & Rote, 2013). This damaged chromosome can lead to abnormal CFTR leading to thick, sticky mucous instead of the thin watery mucous the body needs to fight off infections. The mutation of the gene can be separated into different classes ranging from most sever to milder symptoms. Around 75% of cases are diagnosed by the age of one, usually sooner. Some children are not diagnosed until after ten years of age, typically due to having milder symptoms (McCance, Huether, Brashers, & Rote, 2013). [Show More]
