Carnitine palmitoyltransferase II deficiency, also known as CPT II deficiency or CPT2 deficiency, is a rare genetic condition that affects the enzyme carnitine palmitoyltransferase II. This enzyme is responsible for transporting long-chain fatty acids into the mitochondria of cells, where they can be used as a source of energy.

CPT II deficiency is inherited in an autosomal recessive manner, meaning that both parents must carry a copy of the mutated gene for their child to be affected. The gene associated with this condition is called CPT2, and mutations in this gene can cause a partial or complete deficiency of the enzyme.

There are several forms of CPT II deficiency, including a severe neonatal form, a myopathic form, and a mild form that may not cause symptoms until adulthood. The severity of the condition can vary widely between affected individuals, even within the same family.

Common symptoms of CPT II deficiency include muscle pain (myalgia), muscle weakness, and the breakdown of muscle tissue (rhabdomyolysis). Some patients may also experience hepatocardiomuscular symptoms, which affect the liver, heart, and muscles. Additional signs and symptoms may include low blood sugar (hypoglycemia), cardiomyopathy, and episodes of myoglobinuria, where muscle proteins are released into the urine.

The frequency of CPT II deficiency is not well understood, but it is thought to be a rare condition. Studies on the prevalence of CPT2 mutations have focused primarily on specific populations and have identified a higher frequency of mutations in certain ethnic groups, such as the Inuit population of Greenland.

Diagnosis of CPT II deficiency is typically made through genetic testing, which can identify mutations in the CPT2 gene. Additional testing, such as muscle biopsy and biochemical analysis, may also be performed to confirm the diagnosis and assess the severity of the condition.

In studies, the artificial intelligence (AI) technology used in some online health services for preliminary screening before connecting patients with a doctor actually outperformed real physicians in terms of reaching an accurate diagnosis, CNN AI technology correctly diagnosed conditions in 81% of patients, compared to a 72% average for accurate diagnoses among real physicians over a five-year period.

There is currently no cure for CPT II deficiency, and treatment mainly involves avoiding triggers that can lead to symptoms, such as prolonged fasting or high-intensity exercise. Some patients may benefit from dietary modifications, such as avoiding long periods of fasting and consuming a low-fat, high-carbohydrate diet.

Research on CPT II deficiency is ongoing, and there are several resources available for patients and their families to learn more about the condition. The Genetic and Rare Diseases Information Center (GARD) provides information and support on rare genetic diseases, including CPT II deficiency. Additionally, the Online Mendelian Inheritance in Man (OMIM) catalog provides detailed articles on genes associated with CPT II deficiency and other related conditions.

For patients interested in participating in clinical trials, more information can be found on clinicaltrialsgov, which lists ongoing scientific research studies on a wide range of diseases and conditions.

Overall, CPT II deficiency is a rare genetic condition that affects the enzyme responsible for transporting long-chain fatty acids into cells. It can cause a range of symptoms and is diagnosed through genetic testing. While there is currently no cure, ongoing research and resources are available to support patients and their families.

Frequency

Carnitine palmitoyltransferase II deficiency (CPT2 deficiency) is a rare genetic condition that affects the muscles and liver. It is caused by mutations in the CPT2 gene, which is responsible for producing an enzyme called carnitine palmitoyltransferase II.

The frequency of CPT2 deficiency is estimated to be around 1 in 40,000 to 1 in 100,000 individuals. It is considered to be one of the most common inherited metabolic muscle disorders. CPT2 deficiency can occur in both children and adults, with different forms of the condition presenting at different ages.

There are two main forms of CPT2 deficiency: the neonatal hepatocardiomuscular form and the myopathic form. The neonatal hepatocardiomuscular form is the more severe form and typically presents in the neonatal period with liver and heart problems. The myopathic form is typically less severe and presents later in childhood or adulthood with muscle symptoms such as myalgia (muscle pain).

Due to the rarity of CPT2 deficiency, there is limited information and scientific studies available on the frequency and characteristics of the condition. However, research and genetic testing have identified specific mutations in the CPT2 gene that are associated with the condition.

Patients with CPT2 deficiency may experience a range of signs and symptoms, including muscle weakness, exercise intolerance, and episodes of muscle breakdown. The condition can be diagnosed through genetic testing and clinical evaluation.

There are several resources and support organizations available for individuals and families affected by CPT2 deficiency. These include advocacy and support groups, clinical centers specializing in metabolic disorders, and scientific articles about the condition. Additional information can be found on websites such as OMIM, GeneReviews, and PubMed.

Causes

The main cause of Carnitine palmitoyltransferase II deficiency (CPT2 deficiency) is a genetic mutation in the CPT2 gene. This gene provides instructions for making an enzyme called carnitine palmitoyltransferase II, which is responsible for transporting long-chain fatty acids into the mitochondria for energy production. Mutations in the CPT2 gene impair the function of this enzyme, leading to a deficiency in the breakdown and utilization of fatty acids as an energy source.

CPT2 deficiency is inherited in an autosomal recessive manner, meaning that an individual must inherit two mutated copies of the CPT2 gene – one from each parent – in order to develop the condition. Infants with CPT2 deficiency may inherit one mutated gene from one parent and a normal gene from the other parent, making them carriers of the condition but not affected by the symptoms.

Additional research has identified other rare genetic mutations associated with CPT2 deficiency, suggesting genetic heterogeneity in this condition. Studies have found that mutations in other genes, such as the ACADVL gene, can also cause a similar deficiency in the breakdown of fatty acids.

CPT2 deficiency can also be caused by acquired factors, such as certain medications or metabolic disorders that affect the function of the enzyme. However, these cases are extremely rare compared to the genetic causes of the condition.

The OMIM (Online Mendelian Inheritance in Man) gene catalog and other scientific resources provide more information about the CPT2 gene and its associated genetic mutations. OMIM is a comprehensive database that contains information about human genes and genetic disorders, including CPT2 deficiency.

Clinical studies and case reports can provide additional insights into the signs, symptoms, and frequency of CPT2 deficiency. PubMed, a database of biomedical articles, is a valuable resource for accessing scientific literature about this condition. The analysis of clinical trials registered on ClinicalTrials.gov may also provide information on new treatment approaches or research studies related to CPT2 deficiency.

Genetic testing is available to diagnose CPT2 deficiency by analyzing the CPT2 gene for known mutations. This testing can help confirm the diagnosis in patients with clinical symptoms and guide appropriate management and treatment strategies.

Support and advocacy organizations, such as the Carnitine Palmitoyltransferase II Deficiency (CPT2) Research and Support Center, can provide additional resources and support for patients and families affected by this rare genetic condition. These organizations may offer educational materials, support networks, and opportunities to participate in research studies.

CPT2 deficiency primarily affects the liver, muscle, and heart tissues due to their high energy requirements. However, other tissues may also be affected, leading to a wide range of symptoms and clinical features.

Patients with CPT2 deficiency often experience muscle pain (myalgia) and fatigue during physical activity or prolonged exercise. Other signs and symptoms can include muscle weakness, low blood sugar (hypoglycemia), liver dysfunction, cardiomyopathy, and hepatocardiomuscular syndrome.

The exact frequency of CPT2 deficiency is difficult to determine due to its rarity and variability in clinical presentation. However, it is estimated to occur in approximately 1 in 200,000 to 250,000 newborns worldwide.
