Recent advance in genetic study of hereditary autosomal recessive cerebellar ataxia / 中华医学遗传学杂志

ABSTRACT

Autosomal recessive cerebellar ataxias (ARCA) are a highly heterogeneous group of rare neurodegenerative diseases affecting both central and peripheral nervous systems. Based on pathological mechanisms, five major types of ARCA may be distinguished, which include mitochondrial ataxia, metabolic disorder, DNA repair defect ataxia, congenital ataxias and degenerative ataxia. This review summarizes clinical features, molecular genetics and recent advances in DNA sequencing of common types of ARCA.
