Genetic variation of Omi/HtrA2 and Parkinson's disease

Variants in the Omi/HtrA2 gene have been nominated as a cause of Parkinson's disease. This sequencing study of Omi/HtrA2 in 95 probands with apparent autosomal dominant inheritance of Parkinson's disease did not identify any pathogenic mutations. In addition, there was no association between common variations in the Omi/HtrA2 gene and susceptibility to Parkinson's disease in any of our four patient-control series (n = 2373). Taken together our results do not support a role for Omi/HtrA2 variants in the pathogenesis of Parkinson's disease.
