Hyperlysinemia, also known as saccharopinuria, is a rare genetic condition caused by a deficiency of the enzyme lysine-ketoglutarate reductase. This condition is typically inherited in an autosomal recessive manner.

Hyperlysinemia is characterized by elevated levels of the amino acid lysine and its metabolites, such as saccharopine and pipecolic acid, in the blood and urine. The excess lysine can impair the function of various organs and systems in the body, leading to a range of symptoms.

The symptoms of hyperlysinemia can vary widely from person to person, but may include developmental delay, intellectual disability, seizures, behavioral problems, and skeletal abnormalities. Some individuals with hyperlysinemia may also experience recurrent infections or other health issues.

Genetic testing can be used to confirm a diagnosis of hyperlysinemia. This testing can identify mutations in the LKR/SDH gene, which is responsible for producing the lysine-ketoglutarate reductase enzyme. Genetic testing can also help determine the inheritance pattern of the condition and provide information about the risk of recurrence in future pregnancies.

There is currently no specific treatment for hyperlysinemia. Management of the condition typically involves addressing the individual symptoms and providing supportive care. This may include medications to manage seizures or behavioral issues, physical therapy to address skeletal abnormalities, and ongoing monitoring of lysine levels in the blood and urine.

For more information about hyperlysinemia, including support resources, scientific articles, and genetic testing options, visit the National Organization for Rare Disorders (NORD) or the Online Mendelian Inheritance in Man (OMIM) catalog. These resources can provide valuable information for patients, families, and healthcare professionals seeking to learn more about this rare genetic condition.

Long wait times are often cited as a downfall of universal healthcare systems, but wait times in America have reached a new high, too. The average time to make a physician appointment as a new patient in 15 major U.S. cities is now 24 days, up 30% in just 3 years (2014 to 2018) according to physician recruiting firm Merritt Hawkins.

Frequency

Hyperlysinemia is a rare genetic condition that typically presents with symptoms of impairments in the metabolism of the amino acid lysine. It is inherited in an autosomal recessive manner and is caused by a deficiency of the enzyme saccharopine semialdehyde dehydrogenase (SSADH).

There is limited information available on the genetic frequency of hyperlysinemia. It is considered a rare condition, with only a few cases documented in medical literature. The exact prevalence of hyperlysinemia in the general population is unknown.

Hyperlysinemia is also associated with other genetic disorders, such as saccharopinuria, that involve abnormalities in lysine metabolism. These conditions share similar symptoms and genetic causes.

Additional information on the frequency and genetic causes of hyperlysinemia can be found through genetic testing and scientific research. The Online Mendelian Inheritance in Man (OMIM) catalog and PubMed are valuable resources for learning more about this rare disorder.

For patient support, advocacy, and more information on hyperlysinemia and related diseases, the Genetic and Rare Diseases Information Center (GARD) provides additional resources and references.

Causes

Hyperlysinemia is a genetic condition that is caused by a deficiency in the enzyme saccharopine dehydrogenase (SDH). This enzyme is responsible for breaking down the amino acid lysine in the body.

Hyperlysinemia is typically inherited in an autosomal recessive pattern, meaning that both copies of the SDH gene must be mutated in order for the condition to occur. The frequency of hyperlysinemia in the general population is unknown, but it is considered to be a rare condition.

There are currently no known symptoms associated with hyperlysinemia, and it is often discovered incidentally during routine blood tests. However, some patients with hyperlysinemia may experience symptoms such as developmental delays or intellectual disability.

In addition to hyperlysinemia, mutations in the SDH gene can also cause another condition called saccharopinuria, which is characterized by the presence of high levels of saccharopine (a molecule involved in lysine metabolism) in the urine.

For more information about the genetic causes of hyperlysinemia and saccharopinuria, you can visit resources such as the Online Mendelian Inheritance in Man (OMIM) catalog, which provides detailed information on genes and genetic conditions.

Genetic testing can be performed to confirm a diagnosis of hyperlysinemia. This testing can analyze the SDH gene for mutations and provide additional information about the specific genetic changes present in the patient.

Scientific articles and advocacy organizations may also provide useful information and support for patients and their families. PubMed, for example, is a database that provides access to a wide range of scientific articles on various topics, including genetic diseases.

However, more information about the condition can be found on scientific databases such as PubMed, which contains articles and studies on the genetics and symptoms of hyperlysinemia.

The genes associated with hyperlysinemia are ALDH7A1 and AASS. Mutations in these genes can cause hyperlysinemia, as well as another related condition called saccharopinuria.

For additional information on inheritance and genetic testing for hyperlysinemia, patients and families can consult with a genetics center or other medical professionals specializing in rare genetic diseases. These centers can provide more information on the frequency of the condition, inheritance patterns, and available testing options.

In summary, hyperlysinemia is a rare genetic condition caused by a deficiency in the enzyme that breaks down lysine.

Genetic Testing Information

Genetic testing is an important tool in the diagnosis and management of Hyperlysinemia. This condition is caused by mutations in specific genes that impair the metabolism of lysine, an amino acid. Genetic testing can support the identification of these gene mutations, providing valuable information about the patient’s condition and helping to guide treatment decisions.

There are several genes associated with Hyperlysinemia, including the AASS gene, which is responsible for producing an enzyme called saccharopine dehydrogenase. Mutations in this gene can lead to a deficiency in this enzyme, leading to the accumulation of saccharopine, a molecule that is normally broken down during lysine metabolism.

Genetic testing for Hyperlysinemia can typically be performed through a genetic testing center or laboratory. The frequency of this condition is rare, so specialized testing may be required. This testing can involve analyzing the patient’s DNA to identify mutations in the AASS gene or other genes associated with Hyperlysinemia.

Genetic testing can also provide additional information about the inheritance pattern of Hyperlysinemia. This condition is typically inherited in an autosomal recessive manner, meaning that individuals must inherit two copies of the mutated gene (one from each parent) to develop the condition. Understanding the inheritance pattern can help inform genetic counselling and family planning decisions.

Scientific articles and research papers can be valuable resources for learning more about Hyperlysinemia and genetic testing.
