Fenilcetonúria O Que é

Fenilcetonúria O Que é – Phenylketonuria (PKU) is an inherited genetic metabolic disorder characterized by elevated levels of the amino acid phenylalanine in the blood, brain, and other parts of the body.

Our bodies do not produce this amino acid naturally, so it must be obtained through food. After ingestion, phenylalanine is processed by the enzyme phenylalanine hydroxylase (PAH).

Fenilcetonúria O Que é

People with PKU are deficient or deficient in this enzyme, leading to a build-up of phenylalanine in the body.

June 28 is World Phenylketonuria Day, which aims to raise awareness of this disease, which affects about 1 in 30,000 Brazilians.

PKU manifests itself in three different ways, depending on the amount of PAH enzyme activity:

PKU is an inborn error of metabolism caused by changes in two copies (maternal and paternal) of the PAH gene, which provide instructions for making the enzyme phenylalanine hydroxylase. This enzyme converts phenylalanine to another amino acid, tyrosine, which is used to make melanin (the pigment that gives color to eyes, hair, and skin).

Genetic changes in the PAH gene reduce the activity of the enzyme phenylalanine hydroxylase, which cannot process phenylalanine efficiently, causing this amino acid to reach toxic levels in the blood, brain, and other body tissues.

Neurons are particularly sensitive to high levels of phenylalanine, so high levels of this amino acid can damage the brain and cause the neurological symptoms of PKU.

PKU is inherited in an autosomal recessive manner. Therefore, only those people who inherited the changed gene from their mother and father.

When a child inherits only one altered copy (from either the father or the mother), it is said to have the disease. Carriers do not develop symptoms of the disease, but they can pass the altered gene on to their children.

Fenilcetonúria O Que é

Many people do not know they are carriers of the PAH gene and only find out when they have a sick child.

PKU is included in the SUS National Newborn Screening Program, better known as the paw test, which is a biochemical dose of phenylalanine in the newborn’s blood.

A phenylalanine level greater than 10 mg/dL in at least two different laboratory specimens is required to confirm the diagnosis (ie, the test must be repeated in positive cases).

Some mutations in the PAH gene allow the enzyme to retain some activity and cause milder versions of PKU that can be harder to detect with biochemical tests.

Molecular diagnosis through genetic testing can identify mutations that cause PKU, regardless of disease severity.

Fenilcetonúria: Diagnóstico E Tratamento

Treatment, which must be continued throughout life, consists of a controlled, low-protein, low-phenylalanine diet aimed at maintaining adequate levels of this amino acid in the human body.

Protein-rich foods to avoid or consume in moderation, according to the Ministry of Health:

There are options for common foods like rice and pasta that have been developed specifically for people on the PKU diet.

Although the disease is serious, early diagnosis, even in infants, prevents mental disability and other serious consequences.

Qué Es La Fenilcetonuria Y Cómo Se Detecta

Mothers who have PKU and are no longer on a phenylalanine-restricted diet have a higher risk of having children with intellectual disabilities because the baby may have been exposed to very high levels of phenylalanine during pregnancy. That is why it is very important for women who are pregnant or planning a family to follow a limited diet.

It is important. Dietitian monitoring is necessary to tailor the diet to each patient’s specific needs. Always consult a doctor.

Phenylketonuria is one of the more than 340 diseases that have been checked with the Cheek Test, the first genetic newborn screening test in Brazil.

This genetic test directly analyzes the child’s DNA, so it can determine which mutation in the PAH gene causes the disease.

The cheek test can be performed as soon as the baby is born, even before the appearance of clinical signs of the disease. In addition, the collection is very simple: it is done with a tampon.

The Cheek Test is a newborn genetic screening test that aims to identify babies at risk for diseases that appear in the first months or years of life.

When the child already shows signs of the disease, a diagnostic genetic test is recommended to confirm the suspicion. To diagnose PKU, Mendelics offers several tests that analyze the PAH gene, including the Treatable Disease Panel and the PAH Gene Sequencing Test.

It is important to note that diagnostic tests, unlike screening tests, can only be performed at the discretion and supervision of a physician.
