The disorder belongs to the group of spinocerebellar ataxias and spinal and cerebellar dysplasias. The main clinical manifestations of SCA11 are ataxia, dysarthria, and hypotonia, which progress over time and lead to a significant deterioration in the quality of life of patients. The disease is associated with degeneration of neurons in the cerebellum and spinal cord, which affects motor functions. The pathogenetic mechanism of this disorder, like many other types of spinocerebellar ataxias, is a protein abnormality associated with a gene mutation, which leads to disruption of the integrity of neural tissue and progressive neurological symptoms.<\/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

of the disease and interesting historical facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Spinocerebellar ataxias as a group of diseases were first described in the early 20th century. However, SCA11 was recognized much later, in the early 2000s. The discovery of the link between SCA11 and genetic mutations was made possible by the development of molecular genetics and DNA sequencing methods. Research conducted at that time revealed that this disease is associated with a mutation in the TTTN gene, which plays a key role in the structural integrity of neurons. Since then, data have accumulated on the selective death of neurons in the cerebellum of patients, as well as on characteristic pathological changes at the cellular level, which made it possible to improve the diagnosis and understanding of the pathogenesis of this disorder.<\/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>Prevalence data for spinocerebellar ataxia type 11 remain limited due to diagnostic difficulties and lower prevalence compared to other neurological disorders. The estimated incidence of SCA11 is approximately 1\u20135 cases per 100,000 people in the population. However, the disorder may be more common in certain ethnic groups and regions, highlighting the importance of often overlooked genetic factors. Because the disease often becomes apparent in middle age, increasing population life expectancy has led to an increase in cases possibly attributable to SCA11.<\/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>Spinocerebellar ataxia type 11 is caused by mutations in the TTTN gene on chromosome 2q31. This gene codes for the protein titin, which is involved in the structure of sarcomeres in muscle cells and neurons. The main mutation associated with SCA11 is an increase in the number of repeats in one of the gene\u2019s introns. The presence of this mutation leads to the formation of an abnormal protein that causes toxic effects on cells of the central nervous system. This makes SCA11 an autosomal dominant disorder, and there is a high probability of transmission from parent to offspring.<\/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 spinocerebellar ataxia type 11 are primarily genetic.
