DJ-1 mutations cause autosomal recessive parkinsonism (ARP). Although some reports of DJ-1 mutations have been published, there is lack of information on the prevalence of these mutations in large-scale studies of both familial and sporadic parkinsonism. In this genetic screening study, we analyzed the distribution and frequency of DJ-1 mutations by direct nucleotide sequencing of coding exons and exon-intron boundaries of DJ-1, in 386 parkin-negative parkinsonism patients (371 index cases: 67 probands of autosomal recessive parkinsonism families, 90 probands of autosomal dominant parkinsonism families, 201 patients with sporadic parkinsonism, and 13 with unknown family histories) from 12 countries (Japan 283, China 27, Taiwan 22, Korea 22, Israel 16, Turkey 5, Philippines 2, Bulgaria 2, Greece 2, Tunisia 1, USA 2, Ukraine 1, unknown 1). None had causative mutation in DJ-1, suggesting DJ-1 mutation is very rare among patients with familial and sporadic parkinsonism from Asian countries and those with other ethnic background. This is in contrast to the higher frequencies and worldwide distribution of parkin- and PINK1-related parkinsonism in ARP and sporadic parkinsonism. Thus, after obtaining clinical information, screening for mutations in (1) parkin, (2) PINK1, (3) DJ-1, (4) ATP13A2 should be conducted in that order, in ARP and sporadic parkinsonism, based on their reported frequencies. In addition, haplotype analysis should be employed to check for homozygosity of 1p36, which harbors a cluster of causative genes for ARP such as DJ-1, PINK1 and ATP13A2 in ARP and sporadic parkinsonism, especially in parkinsonism with consanguinity.
