Cystic Fibrosis affects the respiratory tract, the digestive tract, the sweat glands, and the fertility cells. Cystic fibrosis is caused by a mutation in a gene that controls the production of a protein that is needed for the controlling of water balance within a cell. When the water within the cell is abnormal, the pancreas, the lungs and also some other glands throughout the body accumulate thick mucus. The mucus clogs the sweat glands and the salivary glands. One serious symptom of the disease is when thick mucus buildup in the lungs that makes bacterial infections and makes breathing very difficult. …show more content…
CTFR defect in the gene leads to all of the consequences of CF. Over more than 70% of CF patients have the same defect with their CTFR gene, known as delta F508. In, DNA chemical letters called nucleotides, can be arranged or can be mutated, The sequence of the nucleotides are affected in CF by point mutations, where the gene is mutated only at a certain small spot along its length. Delta-F508 has a drastic change on the genes, this mutation the loss of one “letter” in the lengths, the defective gene and one good gene (Orenstein, Spahr, Weiner, 2004). This child will not have symptoms of the disease but, can pass the defective
