The abnormal gene responsible for this disease is passed along from generation to generation by family members who carry it. Genetic diseases like SCA4 occur when one of the body\u2019s 20,000 genes does not work properly. Genes are microscopic structures within the cells of our bodies that contain instructions for every feature a person inherits from his or her parents.\u00a0<\/p><p>SCA4 is an autosomal dominant disease, meaning individuals of either sex are equally likely to inherit the gene and develop the disease. Each child of a person with SCA4 has a 50% chance of inheriting the gene that causes SCA4.\u00a0<\/p><p>In the case of SCA4, it is caused by a mutation called a GGC repeat expansion in the\u00a0<em>ZFHX3\u00a0<\/em>gene. Whether or not you develop SCA4 depends on how many repeats you have.\u00a0<\/p><ul><li><strong>Fewer than 31 GGC Repeats:<\/strong> This is the typical number of repeats in the <em>ZFHX3\u00a0<\/em> People with this number of repeats are healthy.<\/li><li><strong>Between 31 and 41 GGC repeats:<\/strong> Due to limited data, it is not clear what this number of repeats means. It doesn\u2019t seem that people with this length of repeats will develop SCA4, however, their children may be at risk. There is active research to understand what this number of repeats does to the body, but right now there is still uncertainty.<\/li><li><strong>Over 42 GGC repeats<\/strong>: People with more than 42 repeats\u00a0usually develop SCA4.<\/li><\/ul><p>More repeats are associated with an earlier age of onset of symptoms and more severe symptoms. GGC repeats can expand or increase in number between generations. This results in each subsequent generation typically developing SCA4 symptoms at a younger age.<\/p><p>Gene tests can be performed for diagnostic purposes to determine what kind of Ataxia is within a person or family. Genetic testing can also be done, in some circumstances, even before there are symptoms, to determine whether a person carries the abnormal gene or genes that cause Ataxia. This is called predictive or presymptomatic testing. A gene test can also be used to determine whether a fetus has an abnormal Ataxia gene. This is called prenatal testing. Anyone who is considering a predictive or prenatal test should consult with a genetic counselor to discuss the reasons for the test, the possible outcomes, and how those outcomes might affect the person emotionally, medically, or socially.\u202f\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-1de268ec elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"1de268ec\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t\t<div class=\"elementor-background-overlay\"><\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-1137d866\" data-id=\"1137d866\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-59693f28 elementor-widget elementor-widget-heading\" data-id=\"59693f28\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">SCA4 Diagnosis<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-42445a6a elementor-widget elementor-widget-text-editor\" data-id=\"42445a6a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>A neurologist is often the most helpful specialist in recognizing symptoms and diagnosing the disease that\u00a0causes\u00a0Ataxia.\u00a0A neurologic examination can\u00a0determine\u00a0whether a person has symptoms typical of SCA4.\u00a0There are several potential follow-up tests.
