Unverricht-Lundborg disease, or ULD, is the most common form of progressive myoclonus epilepsy. It is caused by mutations in the cystatin B gene.
Description⁚
Unverricht-Lundborg disease, also known as ULD or EPM1, is a rare inherited form of epilepsy characterized by progressive myoclonus epilepsy; It typically manifests between the ages of 6 and 15 years. This disease is caused by mutations in the cystatin B gene (CSTB) and is classified as an autosomal recessive disorder. Individuals with ULD experience episodes of involuntary muscle jerking or twitching, with symptoms worsening over time.
Prevalence and Genetics⁚
Unverricht-Lundborg disease, or ULD, is a rare neurodegenerative disorder caused by mutations in the cystatin B gene. It is considered the most common cause of progressive myoclonic epilepsy globally and is more prevalent in certain regions such as the Baltic area of Europe. Individuals with ULD have two mutated copies of the gene, leading to the characteristic symptoms of the disease.
Symptoms and Diagnosis
People with Unverricht-Lundborg disease experience episodes of involuntary muscle jerking or twitching, with symptoms worsening over time; Diagnosis of this progressive myoclonus epilepsy involves genetic testing for mutations in the cystatin B gene.
Clinical Presentation⁚
Individuals with Unverricht-Lundborg disease experience stimulation-induced myoclonus and seizures. This rare form of epilepsy typically onsets between ages 6 to 15. As the disease progresses, symptoms may include ataxia, intentional tremors, and dysarthria, impacting motor function and coordination. Despite cognitive abilities often remaining within the normal range, emotional lability may be observed.
Diagnosis⁚
Diagnosing Unverricht-Lundborg disease involves genetic testing to identify mutations in the cystatin B gene. The most common mutation involves an expansion mutation, leading to the presence of additional triplets compared to a healthy gene. With approximately 90% of disease alleles exhibiting this mutation, genetic testing plays a crucial role in confirming the diagnosis of this rare inherited form of epilepsy.
Disease Progression and Prognosis
Unverricht-Lundborg disease progresses with symptoms such as myoclonus and seizures worsening over time. The prognosis of individuals with ULD varies, impacting daily activities and quality of life.
Progression of ULD⁚
