Phenylketonuria (PKU) occurs when a person is homozygous for a phenylalanine hydroxylase (PAH) gene mutation. Normally, the PAH gene instructs cells to produce an enzyme that breaks down an amino acid called phenylalanine. In PKU, the cells can’t create the enzyme. This causes phenylalanine to accumulate … See more The cystic fibrosis transmembrane conductance regulator (CFTR) gene makes a protein that controls fluid movement in and out of cells.
