功能: disease:Defects in ATXN2 are the cause of spinocerebellar ataxia type 2 (SCA2) [MIM:183090]; also known as olivopontocerebellar atrophy II (OPCA II or OPCA2). 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 cerebellum degeneration with variable involvement of the brainstem and spinal cord. SCA2 belongs to the autosomal dominant cerebellar ataxias type I (ADCA I) which are characterized by cerebellar ataxia in combination with additional clinical features like optic atrophy, ophthalmoplegia, bulbar and extrapyramidal signs, peripheral neuropathy and dementia. SCA2 is characterized by hyporeflexia, myoclonus and action tremor and dopamine-responsive parkinsonism. SCA2 is caused by expansion of a CAG repeat in the coding region of ATXN2. Longer expansions result in earlier onset of the disease. In some patients with smaller CAG repeat expansions, SCA2 presents as pure familial parkinsonism without cerebellar signs.,polymorphism:The poly-Gln region of ATXN2 is polymorphic: 17 to 29 repeats in the normal population, expanded to about 36 to 52 repeats in spinocerebellar ataxia 2 (SCA2) patients.,similarity:Belongs to the ataxin-2 family.,subunit:Monomer (By similarity). Can also form homodimers.,tissue specificity:Expressed in the brain, heart, liver, skeletal muscle, pancreas and placenta. Isoform 1 is predominant in the brain and spinal cord while isoform 4 is more abundant in the cerebellum. In the brain, broadly expressed in the amygdala, caudate nucleus, corpus callosum, hippocampus, hypothalamus, substantia nigra, subthalamic nucleus and thalamus.,
