Autosomal recessive ataxias affect about 1 person in 20,000. Friedreich ataxia accounts for one-third of the cases in Caucasians; the others are due to a growing list of very rare molecular defects, including mild forms of metabolic diseases. In nearly 50%, the genetic cause remains undetermined.
常染色体隐性共济失调症的发病率约为每 20000 人中有 1 人。弗里德里希共济失调症占高加索人群病例的三分之一;其他病例则是由于越来越多的非常罕见的分子缺陷引起的,包括代谢疾病的轻度形式。近 50%的病例,其遗传原因仍未确定。
