Age of onset ranges from 12 to 65 years. In the approximately 10% of individuals whose onset is before age 25 years disease manifestations are more severe and often different from those with later-onset disease. As the disease progresses, particularly in those with early-onset disease, eye movement abnormalities, dysarthria, dysphagia, sensory neuropathy, upper and lower motor neuron involvement, and orthostatic hypotension can further aggravate balance and gait problems. Most individuals eventually require a walker or wheelchair. Reduced life expectancy in individuals with earlier-onset severe SCA4 is associated with weight loss, infections, and cardiac arrhythmia. Life expectancy is normal or near normal in individuals with later-onset SCA4." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln">Spinocerebellar ataxia type 4 (SCA4) is a progressive neurologic disease characterized by cerebellar involvement (gait ataxia, balance disturbances, eye movement abnormalities), brain stem involvement (dysarthria, dysphagia), sensory neuropathy, motor neuron involvement (muscle wasting and spasticity), autonomic dysfunction (especially orthostatic hypotension), and cognition and/or behavior manifestations. Age of onset ranges from 12 to 65 years. In the approximately 10% of individuals whose onset is before age 25 years disease manifestations are more severe and often different from those with later-onset disease. As the disease progresses, particularly in those with early-onset disease, eye movement abnormalities, dysarthria, dysphagia, sensory neuropathy, upper and lower motor neuron involvement, and orthostatic hypotension can further aggravate balance and gait problems. Most individuals eventually require a walker or wheelchair. Reduced life expectancy in individuals with earlier-onset severe SCA4 is associated with weight loss, infections, and cardiac arrhythmia. Life expectancy is normal or near normal in individuals with later-onset SCA4. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div>

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Spinocerebellar ataxia-4 (SCA4) is an autosomal dominant neurologic disorder characterized by the onset of balance disturbances and gait and limb ataxia usually in the fourth decade, although earlier onset in the teens or twenties has been reported. There is evidence of genetic anticipation within families. The disorder is slowly progressive, and most patients eventually become wheelchair-bound. Additional features include hypometric or slow saccades, sensory or sensorimotor axonal peripheral neuropathy, dysarthria, and autonomic dysfunction, including orthostatic hypotension and problems with bowel or bladder control. More severely affected individuals have dysphagia and significant unintended weight loss, which may contribute to premature death. Brain imaging shows cerebellar atrophy (Wallenius et al., 2024).&#13;
