The Genetic Link To Parkinson S Disease Johns Hopkins Medicine Thanks to recent advances in the lab, including the pinpointing of several parkinson's genes, research is exploding. scientists are now picking apart newly discovered biochemical pathways involved in the disease and uncovering new targets for therapy. Parkinson’s causes are likely a blend of genetics and environmental or other unknown factors. “about 10 to 20 percent of parkinson’s disease cases are linked to a genetic cause,” says ted dawson, m.d., ph.d. , director of the institute for cell engineering at johns hopkins.
Parkinson S Disease Genetics Cause Risk Or Protection Aligning The aberrant protein alpha synuclein is known to be involved in the development of parkinson’s disease, but how and why this abnormal form develops remains an area of active investigation. liana rosenthal, a neurologist at johns hopkins, examines the role of genetics. The genetic landscape of parkinson’s disease (pd) is characterised by rare high penetrance pathogenic variants causing familial disease, genetic risk factor variants driving pd risk in a significant minority in pd cases and high frequency, low. Here, we review advances obtained from models of dominant mutations in α synuclein and lrrk2 as well as recessive pink1, parkin and dj 1 muta tions. recent genome wide association studies have implicated genetic variability at two of these loci, α synuclein and lrrk2, as significant risk factors for developing sporadic pd. These genetic studies have provided novel insight into potential mechanisms underlying the aetiology of pd. this chapter will provide a profile of the genes conclusively linked to pd and will outline the mechanisms of pd pathogenesis implicated by genetic studies.

Abundant evidence points to a protein called alpha synuclein in causing the range of symptoms seen in parkinson’s disease, with the condition progressing as it travels up to the brain. johns hopkins neurologist liana rosenthal describes the process. In this review, we outline the journey thus far of pd genetics, highlighting how significant advances have improved our knowledge of the genetic basis of pd risk, onset and progression. Working with lab grown human brain cells, johns hopkins researchers report they have uncovered a much sought after connection between one of the most common genetic mutations in parkinson’s disease and the formation of fatty plaques in the brain thought to contribute to the destruction of motor neurons that characterize the disease.
