✦ Synopsis

Abstract

Tyrosine hydroxylase (TH) is a theoretical candidate gene determining susceptibility to Parkinson's disease (PD), and an association between one allele of a polymorphism at the TH locus and sporadic PD has been reported. We investigated TH polymorphism in 44 patients with sporadic PD, 48 patients with familial PD and 89 of their unaffected relatives, and 50 control subjects. No evidence of allelic association was detected in either familial or sporadic PD, and linkage analysis excluded the TH locus, or a closely linked gene, as a major determinant of familial PD.

## Abstract Recent whole genome association studies provided little evidence that polymorphisms at the familial Parkinsonism loci influence the risk for Parkinson's disease (PD). However, these studies are not designed to detect the types of subtle effects that common variants may impose. Here, we

## Abstract Mutations in parkin are the second most common known cause of Parkinson's disease (PD). Parkin is an ubiquitin E3 ligase that monoubiquitinates and polyubiquitinates proteins to regulate a variety of cellular processes. Loss of parkin's E3 ligase activity is thought to play a pathogenic

## Abstract Among mutations associated with autosomal dominant and sporadic Parkinson's disease (PD) the G2019S substitution in the leucine‐rich repeat kinase 2 (LRRK2) gene is the most frequently identified. To estimate its frequency in Russia, we analyzed 208 patients with PD from the Northwester
