Screening for a recently identified mutation shown to cause approximately 5%-6% of familial and 1%-2% of apparently sporadic cases of Parkinson's disease will likely become an important component of genetic testing and counseling for this disease, according to investigators involved in the research.

"No other single mutation identified so far ... has occurred with such high frequency" in patients with Parkinson's disease, said William C. Nichols, Ph.D., of Cincinnati Chi...
