Repetitive Genetic Variations Tied to Parkinson’s Risk in Study

Variations in small, repetitive DNA sequences called short tandem repeats (STRs) are associated with an altered risk of developing Parkinson’s disease, a new study reports. “We demonstrate for the first time that these complex repeat regions in fact influence a person’s risk of disease and chip away at understanding…

Parkinson’s May Share a Genetic Link with Crohn’s Disease, Study Finds

Mutations in the LRRK2 gene, a major genetic factor contributing to Parkinson’s disease, may likely affect the risk for Crohn’s disease, an inflammatory bowel disease, researchers at Mount Sinai in New York discovered. The results suggest a potential genetic link between Crohn’s disease and Parkinson’s and common disease…
