Abstract

The development of common age-related neurodegenerative disorders as Parkinson's disease and Alzheimer's disease (AD) are influenced by genetic factors. Recently, pathogenic mutations in the leucine-rich repeat kinase 2 (LRRK2) gene have been identified in familial Parkinsonism. Individuals in some of these families developed symptoms of dementia with Lewy-bodies and AD. The LRRK2 gene is also located within a locus on chromosome 12 reported in late-onset AD, and is therefore a good candidate gene for dementia. A series of 242 patients from Norway diagnosed clinically with dementia were included in the study, the majority were diagnosed with AD. Individuals were screened for the presence of seven known pathogenic mutations previously reported in the LRRK2 gene. We did not identify LRRK2 mutations in our series of dementia patients, indicating that known pathogenic mutations are not common in patients clinically diagnosed with AD. However, these results do not exclude a possible role of other genetic variants within the LRRK2 gene in AD or other forms of dementia.
