[Mutation analysis of ATP13A2 gene in Chinese patients with familial autosomal recessive early-onset parkinsonism].

Objective: To investigate the mutation characteristics of ATP13A2 gene in Chinese patients with familial autosomal recessive early-onset parkinsonism (AREP).
Methods: Mutations of ATP13A2 gene were screened by polymerase chain reaction combined with DNA direct sequencing in patients with familial AREP.
Results: No pathogenic mutations in ATP13A2 gene were detected in this group. Six reported polymorphisms were identified. They were IVS6+70A>G, IVS12+66A>G, m.1849C>T, IVS20-56 G>A, m2671C>T and m2824G>A.
Conclusion: ATP13A2 gene mutations may be rare in Chinese patients with familial autosomal recessive early-onset parkinsonism.
