Progress in Genetic Studies of Tourette’s Syndrome

Brain Sciences, 2017
Tourette’s Syndrome (TS) is a complex disorder characterized by repetitive, sudden, and involuntary movements or vocalizations, called tics. Tics usually appear in childhood, and their severity varies over time.

Variable Effects of PD-Risk Associated SNPs and Variants in Parkinsonism-Associated Genes on Disease Phenotype in a Community-Based Cohort

Frontiers in Neurology, 2021
Genetic risk factors for Parkinson's disease (PD) risk and progression have been identified from genome-wide association studies (GWAS), as well as studies of familial forms of PD, implicating common variants at more than 90 loci and pathogenic or likely

Psychometric precision in phenotype definition is a useful step in molecular genetic investigation of psychiatric disorders [PDF]

, 2015
Affective disorders are highly heritable, but few genetic risk variants have been consistently replicated in molecular genetic association studies. The common method of defining psychiatric phenotypes in molecular genetic research is either a summation ...

ALDH1A1 Genetic Variations May Modulate Risk of Parkinson’s Disease in Han Chinese Population

Frontiers in Neuroscience, 2021
Background: Studies in animal models have suggested that aldehyde dehydrogenase 1 (encoded by ALDH1A1) protects against Parkinson’s disease (PD) by reducing toxic metabolites of dopamine.

Association of polymorphisms in the heparanase gene (HPSE) with hepatocellular carcinoma in Chinese populations

Genetics and Molecular Biology, 2017
Heparanase activity is involved in cancer growth and development in humans and single nucleotide polymorphisms (SNPs) in the heparanase gene (HPSE) have been shown to be associated with tumors.

Robust Tests in Genome-Wide Scans under Incomplete Linkage Disequilibrium [PDF]

, 2009
Under complete linkage disequilibrium (LD), robust tests often have greater power than Pearson's chi-square test and trend tests for the analysis of case-control genetic association studies.
