<unk>  <unk>  is a form of spinocerebellar ataxia inherited in an autosomal<unk>  manner.<unk>  is a genetically inherited condition that causes deterioration of the nervous system leading to disorder and a decrease or loss of function to regions of the body. Degeneration occurs at the cellular level and in certain subtypes results in cellular death. Cellular death or dysfunction causes a break or faulty signal in the line of communication from the central nervous system to target muscles in the body. When there is impaired communication or a lack of communication entirely, the muscles in the body do not function correctly. Muscle control complications can be observed in multiple balance, speech, and motor or movement impairment symptoms.<unk>  is divided into three types and further subdivided into subtypes known as SCAs (spinocerebellar ataxias).
Autosomal dominant cerebellar ataxia
Autosomal recessive cerebellar ataxia
Non-progressive congenital ataxia
Benign hereditary chorea
Spinal muscular atrophy with lower extremity predominance 1
Autosomal recessive cerebellar ataxia type 1
Tropical ataxic neuropathy
Spinocerebellar ataxia
