The Phenylketonuria Market Size is expected to reach USD 1121. Phenylketonuria: tyrosine supplementation in phenylalanine restricted diets. Our bodies break down the protein in foods, such as meat and fish, into amino acids, which are the "building blocks" of protein. Since amino acids make up proteins, this can result in difficulty processing high protein foods. There is some broad genotype-phenotype correlation (alleles that tend to be severe and alleles that tend to be mild), but unrelated individuals with identical mutations have some degree of variability in phenylalanine tolerance.
