Advance of the study on LRRK2 gene in Parkinson's disease / 中华医学遗传学杂志

ABSTRACT

The leucine-rich repeat kinase2 (LRRK2) has been identified to be the gene causing autosomal dominant inherited Parkinson's disease(PD)8. The clinical features of this type of PD are similar to those of idiopathic PD, but the pathological changes are diverse. The mutation types and frequencies of the LRRK2 distribute unevenly in different populations. LRRK2 is a large complex protein with multiple functions and expresses widely in human body. Sequence alignment shows that LRRK2 might be a multiple function kinase for substrate phosphorylation and might also act as a scaffolding protein. Further study on the physiological function and pathogenic mechanism of LRRK2 will help to find out the possible pathogenesis and new treatment for PD.
