Summaries for Spinocerebellar Ataxia 11

NIH Rare Diseases : 53 Spinocerebellar ataxia type 11 (SCA11) is characterized by progressive cerebellar ataxia (difficulty walking and balance) and abnormal eye signs (jerky pursuit, horizontal and vertical movements (nystagmus), pyramidal features (increased muscular tonus, increased reflexes and an abnormal reflex known as Babinski sign and inability to make to perform fine movements), peripheral neuropathy with numbness, weakness or pain in the feet or hands or other places of the body and dystonia. It is a very rare disease and very few patients have been reported to date. In them, age of onset ranged from the early teens to the second decade of life and life span was normal. Diagnosis is based on signs and symptoms and with a genetic exam showing an alteration (mutation) in the TTBK2 gene. It is inherited in an autosomal dominant manner. Treatment may include speech and language therapy for talking and swallowing problems, occupational therapy, including home adaptations, physiotherapy and use of assistive walking devices and ankle-foot orthotics (AFOs) for those with neuropathy.

MalaCards based summary : Spinocerebellar Ataxia 11, also known as spinocerebellar ataxia type 11, is related to autosomal dominant cerebellar ataxia and spinocerebellar ataxia, autosomal recessive 11. An important gene associated with Spinocerebellar Ataxia 11 is TTBK2 (Tau Tubulin Kinase 2), and among its related pathways/superpathways are Organelle biogenesis and maintenance and Alzheimers Disease Pathway. Affiliated tissues include eye, spinal cord and cerebellum, and related phenotypes are dysarthria and dysphagia

UniProtKB/Swiss-Prot : 75 Spinocerebellar ataxia 11: Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA11 is an autosomal dominant cerebellar ataxia (ADCA). It is a relatively benign, late- onset, slowly progressive neurologic disorder.
