The genetic etiology of amyotrophic lateral sclerosis (ALS) is not well understood. Finland has one of the highest incidence of ALS in the world, making it an ideal population for study. To identify genetic risk factors for this fatal neurodegenerative disease, we undertook a genome-wide associ...

The NINDS repository (http://ccr.coriell.org/ninds/) was established in October 2001 with the goal of developing standardized, broadly useful diagnostic and other clinical data, as well as a collection of DNA and cell line samples to further advance g...

The NINDS repository was established in October 2001 with the goal of developing standardized, broadly useful diagnostic and other clinical data, as well as a collection of DNA and cell line samples to further advance gene discovery of neurological disorders. All samples and both phenotypic and g...

The cause of sporadic amyotrophic lateral sclerosis (ALS) is unknown. To identify the genetic factors underlying this fatal neurodegenerative disease, we performed a series of genome-wide association studies of ALS. These studies are divided into three distinct stages, each associated with a se...

Epidemiological studies have estimated a cumulative prevalence of PD of greater than 1 per thousand. When prevalence is limited to senior populations, this proportion increases nearly 10-fold. The estimated genetic risk ratio for PD is approximately 1.7 (70% increased risk for PD if a sibling...

The purpose of this project was to conduct a genome-wide associate study to search for the genetic factors that predispose to myasthenia gravis. The rationale for this study lies in the fact that, although the immunological and physiological processes affecting the neuromuscular junctions of myas...
