Phenylketonuria (PKU) Fact Sheet

What is Phenylketonuria (PKU)?

Phenylketonuria (PKU) is a rare inherited metabolic disorder that affects how the body processes the amino acid phenylalanine. Phenylalanine is found in many protein-containing foods and some artificial sweeteners. If left untreated, high levels of phenylalanine can build up in the blood, leading to intellectual disability and other serious health problems.

Causes

PKU is caused by mutations in the PAH gene, which provides instructions for making an enzyme called phenylalanine hydroxylase. This enzyme is necessary to convert phenylalanine into another amino acid, tyrosine. When the PAH gene is mutated, phenylalanine hydroxylase activity is reduced or absent, leading to the accumulation of phenylalanine in the body.

Inheritance Pattern

PKU is inherited in an autosomal recessive pattern, meaning both copies of the PAH gene (one from each parent) must be altered for an individual to be affected. Parents of a child with PKU are typically carriers of one altered gene each but do not show signs and symptoms of the condition.

Symptoms

Symptoms of PKU can vary widely but often include:

• Intellectual disability

• Behavioral problems

• Seizures

• Developmental delays

• Eczema

• Musty odor in breath, skin, or urine due to phenylalanine buildup

• Fair skin and blue eyes (due to lack of melanin production)

• Microcephaly (small head size)

Diagnosis

PKU is usually diagnosed through newborn screening. In many countries, all newborns are screened for PKU a few days after birth using a blood test. If high levels of phenylalanine are detected, further testing is conducted to confirm the diagnosis.

Management and Treatment

The primary treatment for PKU is a strict diet low in phenylalanine. Key components of management include:

Dietary Management

• Low-Phenylalanine Diet: Individuals with PKU must follow a diet that restricts phenylalanine intake. This means avoiding high-protein foods such as meat, fish, eggs, dairy products, nuts, and certain beans.

• Medical Foods and Formulas: Special medical foods and phenylalanine-free formulas are essential to provide necessary nutrients while maintaining low phenylalanine levels.

• Frequent Monitoring: Regular blood tests are needed to monitor phenylalanine levels and ensure they remain within a safe range.

Medications

• Sapropterin (Kuvan): This medication can help lower phenylalanine levels in some people with PKU by increasing the activity of the phenylalanine hydroxylase enzyme.

Other Treatments

• Gene Therapy and Enzyme Replacement Therapy: Research is ongoing into potential gene therapy and enzyme replacement therapy options, which may offer new treatment avenues in the future.

Prognosis

With early and consistent treatment, individuals with PKU can lead healthy lives with normal intellectual development. However, if the diet is not strictly followed, high phenylalanine levels can cause severe brain damage and intellectual disability.

Complications

If left untreated or poorly managed, PKU can lead to:

• Severe intellectual disability

• Behavioral problems

• Seizures

• Psychiatric disorders

• Neurological problems

Living with PKU

Living with PKU requires lifelong dietary management and regular medical supervision. Key aspects include:

• Dietary Adherence: Sticking to the prescribed diet is crucial for managing PKU.

• Education and Support: Educating family members, teachers, and caregivers about PKU helps in providing necessary support.

• Psychosocial Support: Counseling and support groups can be beneficial for individuals with PKU and their families.

Galactosemia Fact Sheet

What is Galactosemia?

Galactosemia is a rare genetic metabolic disorder that affects an individual’s ability to process galactose, a simple sugar found in lactose, which is present in milk and dairy products. In individuals with galactosemia, the enzyme responsible for converting galactose into glucose is deficient or inactive. As a result, galactose accumulates in the blood, leading to serious health complications.

Types of Galactosemia

1. Classic Galactosemia (Type I): The most severe form, caused by a deficiency of the enzyme galactose-1-phosphate uridylyltransferase (GALT).

2. Galactokinase Deficiency (Type II): Caused by a deficiency of the enzyme galactokinase (GALK), leading primarily to cataracts.

3. Galactose Epimerase Deficiency (Type III): Caused by a deficiency of the enzyme UDP-galactose-4-epimerase (GALE), with varying severity.

Causes

Galactosemia is an autosomal recessive genetic disorder, meaning both copies of the gene (one from each parent) must be altered for the individual to be affected. The specific gene mutations responsible for galactosemia are:

• GALT gene for Classic Galactosemia (Type I)

• GALK1 gene for Galactokinase Deficiency (Type II)

• GALE gene for Galactose Epimerase Deficiency (Type III)

Symptoms

Symptoms of galactosemia can appear within the first few days of life after the ingestion of breast milk or formula. Common symptoms include:

• Poor feeding

• Vomiting

• Diarrhea

• Jaundice (yellowing of the skin and eyes)

• Lethargy

• Failure to gain weight

• Liver enlargement

• Cataracts

• Susceptibility to infections

• Sepsis (severe infection)

If left untreated, galactosemia can lead to severe complications such as intellectual disability, liver damage, kidney failure, and even death.

Diagnosis

Galactosemia is typically diagnosed through newborn screening. A blood test measures the levels of galactose and galactose-1-phosphate or assesses the activity of the GALT enzyme. Additional tests to confirm the diagnosis may include:

• Genetic Testing: Identifies mutations in the GALT, GALK1, or GALE genes.

• Enzyme Activity Assays: Measures the activity of the enzymes involved in galactose metabolism.

Management and Treatment

The primary treatment for galactosemia is a lifelong dietary restriction of galactose. Key components of management include:

Dietary Management

• Galactose-Free Diet: Individuals with galactosemia must avoid all milk and dairy products, as well as other foods containing galactose. This includes lactose-containing foods such as certain processed foods and some medications.

• Special Formulas: Infants diagnosed with galactosemia are fed soy-based or elemental formulas that do not contain lactose.

Monitoring and Support

• Regular Monitoring: Frequent monitoring of galactose-1-phosphate levels in the blood is essential to ensure dietary compliance and manage the condition.

• Nutritional Support: Consulting with a dietitian specialized in metabolic disorders can help ensure a balanced diet while avoiding galactose.
