Phenylketonuria type of mutation

Web27. máj 2024 · Mutations in the PAH gene that cause the enzyme not to function are the main cause of phenylketonuria, but rare mutations that cause low BH4 levels are also linked to causing phenylketonuria. The buildup of phenylalanine is a problem in infancy and causes neurological issues in the developing brain, resulting in intellectual disability. WebMutations in the human gene for phenylalanine hydroxylase (PAH) cause the metabolic disorder known as phenylketonuria. Molecular analysis (DNA sequencing) of many PAH alleles in the human population has yielded examples of many types of mutant defects.
