WebbThe defect in Phenylketonuria (PKU) is caused by a lack of the enzyme phenylalanine hydroxylase, which converts the amino acid phenylalanine into the amino acid tyrosine. If untreated, PKU infants will develop severe metal retardation, but if the infants are fed tyrosine they develop normally. Infants with PKU are fed less phenylalanine. Webb12 okt. 2024 · Phenylketonuria (PKU; McKusick #261600) is a rare autosomal recessive inborn error of phenylalanine (Phe) metabolism caused by variants in the gene encoding phenylalanine hydroxylase (PAH). PAH normally converts Phe into tyrosine (Tyr) requiring the cofactor tetrahydrobiopterin (BH4), molecular oxygen and iron (Fig. 1) [ 1 ].
WebbA karyotype is simply a picture of a person's chromosomes. In order to get this picture, the chromosomes are isolated, stained, and examined under the microscope.
