The disorder is caused by a deficiency of a specific protein responsible for the oxidation of long-chain fatty acids in the mitochondria, which in turn leads to the accumulation of toxic intermediates and disruption of cellular energy metabolism. Clinical manifestations of the disease range from mild muscle weakness and fatigue to more serious conditions including myopathy and cardiomyopathy. Given the metabolic consequences, this defect can affect multiple body systems, including the nervous, cardiovascular and muscular systems.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_86

of the disease and interesting historical facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The history of studying mitochondrial trifunctional protein deficiency dates back to the end of the 20th century, when data on genetic disorders leading to metabolic disorders began to appear. In 1987, a significant event in the field of medicine occurred: scientists discovered the genetic basis of a number of cases of myopathies associated with impaired oxidation of fatty acids. Since then, attention to this disease has increased, new mutations and causes have been identified. Interestingly, the deficiency of this protein has also been identified in certain animals, which has allowed us to better understand the mechanisms of its pathogenesis and potential treatment methods.<\/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>Mitochondrial trifunctional protein deficiency is considered an orphan disease with low prevalence. According to statistical studies, the incidence of this disease is approximately 1 in 100,000 newborns. However, this rate may vary depending on ethnic group and geographic location. Some regional studies indicate a higher incidence due to specific mutations characteristic of individual populations. Early diagnosis plays a key role in managing the disease and improving the quality of life of patients.<\/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>The main gene associated with mitochondrial trifunctional protein deficiency is called ETFDH (primary gene encoding trifunctional protein involved in fatty acid oxidation). Mutations in this gene can lead to dysfunction and, consequently, to the development of the disease. More than 50 different mutations associated with pronounced clinical manifestations are known. Genetic testing allows for an accurate diagnosis and identification of gene carriers in families, which is an important aspect in family planning and determining the risks for future generations.<\/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>The main risk factors that may contribute to the development of mitochondrial trifunctional protein deficiency include:<\/p>\n<ul>\n<li>Heredity - the disease is transmitted in an autosomal recessive manner.<\/li>\n<li>Presence of previous cases of the disease in the parents&#039;
