2022年5月13日 · Phenylketonuria (fen-ul-key-toe-NU-ree-uh), also called PKU, is a rare inherited disorder that causes an amino acid called phenylalanine to build up in the body. PKU is caused by a change in the phenylalanine hydroxylase (PAH) gene.

2023年8月8日 · Phenylketonuria (PKU) is an inborn error of metabolism (IEM) most often caused by missense mutations in the gene encoding phenylalanine hydroxylase (PAH), which catalyzes the hydroxylation of phenylalanine (Phe) to generate tyrosine (Tyr).

What are common symptoms of phenylketonuria (PKU)? Children with untreated PKU appear healthy at birth. But by 3 to 6 months of age, they begin to lose interest in their surroundings. By age 1, children are developmentally delayed and their skin has less pigmentation than that of someone without the condition.

2018年9月20日 · Phenylketonuria (PKU), the most common inborn error of amino acid metabolism, results from an impaired ability to metabolize the essential amino acid phenylalanine. Deficiency of the enzyme...

Phenylketonuria is a genetic condition where levels of phenylalanine build up in your body. If left untreated, phenylketonuria can affect a person’s cognitive development. Treatment with medications and/or dietary changes help reduce symptoms.

Clinical manifestations. If PKU is untreated, patients can experience severe intellectual disability, epilepsy, seizures, psychiatric movement behaviors, microcephaly, generalized hypopigmentation of skin (including eyes and hair), eczema, and a musty sweat odor . However, with early intervention after birth, dietary treatment can prevent sequelae.

Phenylketonuria (or PKU) is a rare, inherited disorder that prevents children from breaking down certain amino acids in their bodies. This leads to toxic levels of phenylalanine and a dangerously low level of tyrosine. In healthy children, these two amino acids work together to keep the body functioning properly.

2023年12月20日 · Phenylalanine (Phe) builds up in the blood as a result of PAH mutations. Untreated PKU can result in several dangers, including brain damage. Due to factors including enhanced genetic testing and...

2012年7月9日 · Phenylketonuria (PKU) is an autosomal recessive inborn error of phenylalanine (Phe) metabolism caused by mutations in phenylalanine hydroxylase ( PAH) gene. It is one of the most prevalent metabolic disorders, with a high frequency (around 1/10,000) among Caucasians.

2017年7月25日 · Phenylketonuria (PKU) is a rare genetic condition that causes an amino acid called phenylalanine to build up in the body. Amino acids are the building blocks of protein. Phenylalanine is found in...
