Autosomal recessive: cystic fibrosis (CF), sickle cell anemia (SC), Tay Sachs disease. Genes are inherited from our biological parents in specific ways. One of the basic patterns of inheritance of our genes is called autosomal recessive inheritance.
Introduction. Cystic Fibrosis is an inherited disease caused by a genetic mutation (defect) on chromosome 7. The defective gene results in abnormalities in the production and function of a protein called the cystic fibrosis transmembrane conductance regulator (CFTR).In healthy cells CFTR acts as a chloride channel and a regulator of sodium, chloride and bicarbonate transport.ntroduction.
