This disorder is characterized by abnormally high levels of lysine in the blood serum, which can lead to various metabolic disorders. Hyperlysinemia most often results from a deficiency of the enzyme responsible for lysine catabolism, which in turn can cause toxic effects and damage to the central nervous system. Clinical manifestations of the disease can range from neurological disorders to mental illness, making early diagnosis and effective treatment essential to improve the quality of life of patients.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_86 counter-flat ez-toc-counter ez-toc-light-blue ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p

of the disease and interesting historical facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Hyperlysinemia was first described in the scientific literature in the 1960s. The first documented cases were found in children who showed symptoms of intellectual disability and other neurological disorders. In 1967, the first genetic testing was conducted, which established a link between hyperlysinemia and mutations in the genes responsible for the synthesis of enzymes involved in lysine metabolism. The Finnish population has been a leader in the study of this disease, which has led to the discovery of many carriers and an increase in our knowledge of the pathophysiology of hyperlysinemia.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%AD%D0%BF%D0%B8%D0%B4%D0%B5%D0%BC%D0%B8%D0%BE%D0%BB%D0%BE%D0%B3%D0%B8%D1%8F\"><\/span>Epidemiology<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Hyperlysinemia is a rare disease with low prevalence in the population. According to various studies, the frequency of occurrence of this disorder is from 1 in 50,000 to 1 in 100,000 newborns. In some regions, especially in countries with high levels of inbreeding, the frequency may be significantly higher. According to the World Health Organization, direct studies on the prevalence of the disease remain limited, which makes it difficult to accurately understand the epidemiological picture.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%93%D0%B5%D0%BD%D0%B5%D1%82%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B0%D1%8F_%D0%BF%D1%80%D0%B5%D0%B4%D1%80%D0%B0%D1%81%D0%BF%D0%BE%D0%BB%D0%BE%D0%B6%D0%B5%D0%BD%D0%BD%D0%BE%D1%81%D1%82%D1%8C_%D0%BA_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%BC%D1%83_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8E\"><\/span>Genetic predisposition to this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Hyperlysinemia is primarily caused by mutations in the SLC7A7 and SLC6A20 genes, which encode transporters responsible for transporting lysine in cells. Mutations in these genes can lead to dysfunction of the transport systems, which in turn leads to accumulation of lysine in the plasma. Genetic testing can help in early diagnosis and identification of gene carriers, especially in families with a history of the disease.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%A4%D0%B0%D0%BA%D1%82%D0%BE%D1%80%D1%8B_%D1%80%D0%B8%D1%81%D0%BA%D0%B0_%D0%B2%D0%BE%D0%B7%D0%BD%D0%B8%D0%BA%D0%BD%D0%BE%D0%B2%D0%B5%D0%BD%D0%B8%D1%8F_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>Risk factors for the development of this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Risk factors for hyperlysinemia under investigation include:<\/p>\n<ul>\n<li>Heredity - the presence of cases of the disease in the family increases the likelihood of inheriting the gene.<\/li>\n<li>Inbreeding is the increase in the likelihood of disease in populations with limited genetic diversity.<\/li>\n<li>Gender - Some studies suggest an increased predisposition in men.<\/li>\n<\/ul>\n<p>Environmental and lifestyle factors do not play a significant role in the development of the disease, but it is important to note that metabolic stress may exacerbate the manifestations of the disease in already predisposed individuals.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%94%D0%B8%D0%B0%D0%B3%D0%BD%D0%BE%D1%81%D1%82%D0%B8%D0%BA%D0%B0_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>Diagnosis of this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Diagnosis of hyperlysinemia is based on a comprehensive approach, including:<\/p>\n<ul>\n<li>The main symptoms are mental retardation, epileptic seizures, hyperkinesis.<\/li>\n<li>Laboratory tests, including blood tests for lysine levels and enzyme activity.<\/li>\n<li>Radiological examinations, such as MRI of the brain, which reveal signs of neurodegenerative changes.<\/li>\n<li>Other diagnostic tests, including molecular genetic testing, to confirm the diagnosis.<\/li>\n<li>Differential diagnosis - exclusion of other diseases similar to hyperlysinemia, for example, Chorea or other metabolic disorders.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"%D0%9B%D0%B5%D1%87%D0%B5%D0%BD%D0%B8%D0%B5\"><\/span>Treatment<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Treatment of hyperlysinemia is based on a multifunctional approach and includes:<\/p>\n<ul>\n<li>General treatment is consultation with nutritionists to formulate a diet low in lysine.<\/li>\n<li>Pharmacological treatment is the prescription of drugs to correct metabolic processes and support the patient\u2019s systemic state.<\/li>\n<li>Surgical treatment - in rare cases, may be required to eliminate complications caused by the disease.<\/li>\n<li>Other treatments include physical therapy and neuropsychological support, which is especially important for children with developing motor and cognitive functions.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"%D0%A1%D0%BF%D0%B8%D1%81%D0%BE%D0%BA_%D0%BB%D0%B5%D0%BA%D0%B0%D1%80%D1%81%D1%82%D0%B2_%D0%BF%D1%80%D0%B8%D0%BC%D0%B5%D0%BD%D1%8F%D0%B5%D0%BC%D1%8B%D1%85_%D0%B4%D0%BB%D1%8F_%D0%BB%D0%B5%D1%87%D0%B5%D0%BD%D0%B8%D1%8F_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>List of medications used to treat this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>To date, there are no specific drugs aimed exclusively at treating hyperlysinemia, but the following groups of substances may be recommended:<\/p><script data-noptimize=\"\" data-wpfc-render=\"false\">\nfpm_start( \"true\" );\n<\/script>\n\n<ul>\n<li>Amino acid complex supplements.<\/li>\n<li>Drugs that improve cerebral circulation.<\/li>\n<li>Hypnotics and anticonvulsants to control the patient&#039;s condition.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"%D0%9C%D0%BE%D0%BD%D0%B8%D1%82%D0%BE%D1%80%D0%B8%D0%BD%D0%B3_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>Disease monitoring<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Monitoring of patients with hyperlysinemia is necessary to control the level of lysine in the blood and assess the effectiveness of therapy.
