We performed a sequence analysis of PINK1 in 115 patients diagnosed with Parkinson's disease (PD) from southern Italy, including 93 sporadic cases with EOPD, 9 familial cases with EOPD, and 13 familial cases with LOPD.
A series of 69 Han Chinese PD patients (including 66 index cases and 3 relatives) with early-onset Parkinson's disease (EOPD) were studied to assess the frequency of parkin and PINK1 gene mutations.
