The main feature of the disease is a significant increase in bone density as a result of insufficient functionality of osteoclasts - cells responsible for bone resorption (destruction). This leads to abnormal accumulation of bone mass, which causes a violation of the structural integrity of the skeleton, a predisposition to fractures and various other complications. Wolman disease can manifest itself in specialized forms with different levels of severity and clinical manifestations. In most cases, it is inherited in an autosomal recessive manner. Without timely intervention, the disease can lead to significant functional limitations and a decrease in the quality of life.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_83 counter-flat

of the disease and interesting historical facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The history of Wolman&#039;s disease dates back to the first half of the 20th century, when clinical cases corresponding to modern concepts of this disease were first described. One of the first proofs of the existence of the disease was presented in 1939, when the German physician Wolman identified a specific form of osteodystrophy in children. Since then, the scientific literature has been replenished with many clinical observations, descriptions and studies on the etiology, pathogenesis and treatment of this disease. In the 1980s, the first steps were taken in the genetic study of the disease, which allowed a better understanding of its hereditary mechanisms. It is noteworthy that among the known cases of the disease there is a connection with certain ethnic groups, which emphasizes the genetic predisposition and the importance of early diagnosis.<\/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>The epidemiology of Wolman disease is characterized by extremely low prevalence. According to available data, the disease affects approximately 1 in 100,000 newborns, making it one of the rarest genetic disorders. However, the incidence rate may vary depending on the geographic region and ethnic group. In recent decades, there has been interest in the disease from scientific institutions, which facilitates epidemiological studies and the preparation of statistical data. In addition, it is important to note that in some populations, the disease may manifest itself with a higher frequency due to ethnic predisposition.<\/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 primary cause of Wolman disease is mutations in genes that are responsible for normal osteoclast function. The most significant genes include CA2, CLCN7, and TCIRG1. These genes code for proteins that are involved in the process of osteoclastic resorption, making them critical for maintaining balanced bone metabolism. When mutations are present, osteoclast formation and function are disrupted, which in turn causes excess bone accumulation. The disease is inherited in an autosomal recessive manner, meaning that both parents must be carriers of the mutation for the child to develop 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 Wolman disease are largely related to its genetic nature.
