Summaries for Spinocerebellar Ataxia 31

NIH Rare Diseases : 54 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 217012Disease definitionSpinocerebellar ataxia type 31 (SCA31) is a very rare subtype of autosomal dominant cerebellar ataxia type III (ADCA type III; see this term) characterized by the late-onset of cerebral ataxia, dysarthria and horizontal gaze nystagmus, and that is occasionally accompanied by pyramidal signs, tremor, decreased vibration sense and hearing difficulties.EpidemiologySCA31 is the third most common form of ADCA (see this term) in Japan, where more than 20 families have been reported to date. It is rarely found in other Asian countries and is extremely rare in Western countries.Clinical descriptionThe mean age of disease onset is 58 years but it can present between the ages of 8 to 83 years. Ataxia, dysarthria, and horizontal gaze nystagmus are the common manifestations of SCA31 and the disease duration can be more than 10 years. Less common manifestations include pyramidal signs, tremor, decreased vibration sense, and hearing difficulties.EtiologySCA31 is due to non-coding pentanucleotide repeat expansions in the BEAN1 gene (16q21), encoding protein BEAN1.Genetic counselingSCA31 is inherited autosomal dominantly with incomplete penetrance and genetic counseling is possible.Visit the Orphanet disease page for more resources.

MalaCards based summary : Spinocerebellar Ataxia 31, also known as spinocerebellar ataxia type 31, is related to spinocerebellar ataxia 1 and autosomal dominant cerebellar ataxia, and has symptoms including gait ataxia An important gene associated with Spinocerebellar Ataxia 31 is BEAN1 (Brain Expressed Associated With NEDD4 1). Affiliated tissues include cerebellum, eye and spinal cord, and related phenotypes are dysarthria and gait ataxia

Disease Ontology : 12 An autosomal dominant cerebellar ataxia that is characterized by late-onset ataxia, dysarthria and horizontal nystagmus, has material basis in repeat expansion mutation in the BEAN1 gene.

UniProtKB/Swiss-Prot : 76 Spinocerebellar ataxia 31: A form of spinocerebellar ataxia, 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. SCA31 belongs to the autosomal dominant cerebellar ataxias type III (ADCA III) which are characterized by pure cerebellar ataxia without additional signs.
