Summaries for Spinocerebellar Ataxia 5

NIH Rare Diseases : 53 Spinocerebellar ataxia 5 (SCA5) is one of the many spinocerebellar ataxias, which are inherited conditions that cause degeneration of the spinal cord and cerebellum. SCA5 almost exclusively affects the cerebellum. It is considered to be a mild form that progresses slowly. The age of onset is usually between the ages of 20 and 30, but a wide range in age of onset has been reported. Signs and symptoms may include loss of coordination of the hands, arms, and legs; impaired balance when walking; and slurred speech (dysarthria). SCA5 is caused by mutations in the SPTBN2 gene and is inherited in an autosomal dominant manner.

MalaCards based summary : Spinocerebellar Ataxia 5, also known as spinocerebellar ataxia type 5, is related to spinocerebellar ataxia 20 and spinocerebellar ataxia, x-linked 5, and has symptoms including cerebellar ataxia, action tremor and dysdiadochokinesis. An important gene associated with Spinocerebellar Ataxia 5 is SPTBN2 (Spectrin Beta, Non-Erythrocytic 2), and among its related pathways/superpathways are L1CAM interactions and Interaction between L1 and Ankyrins. Affiliated tissues include spinal cord, cerebellum and eye, and related phenotypes are cerebellar atrophy and gait disturbance

Disease Ontology : 12 An autosomal dominant cerebellar ataxia that is characterized by the early-onset of cerebellar signs and eye movement abnormalities with a very slow disease progression, and has material basis in mutation in the SPTBN2 gene.

OMIM : 57 For a general discussion of autosomal dominant spinocerebellar ataxia (SCA), see SCA1 (164400). (600224)

UniProtKB/Swiss-Prot : 75 Spinocerebellar ataxia 5: 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. SCA5 is an autosomal dominant cerebellar ataxia (ADCA). It is a slowly progressive disorder with variable age at onset, ranging between 10 and 50 years.
