DJ-1 gene mutations have been found to cause early-onset Parkinson's disease. We report a family from southern Italy with three brothers affected by early-onset parkinsonism, dementia, and amyotrophic lateral sclerosis. Molecular analysis of the DJ-1 gene in two living patients showed a novel homozygous mutation in exon 7 (E163K) and a new homozygous mutation (g.168_185dup) in the promoter region of the gene. Both mutations cosegregated with the disease and were detected in a heterozygous state in the patients' mother and their healthy siblings. Our findings expand the spectrum of clinical presentations associated with mutations in DJ-1 gene. RI Savettieri, Giovanni/E-8411-2012; La Bella, Vincenzo/H-4532-2012

Abstract
DJ-1 gene mutations have been found to cause early-onset Parkinson's disease. We report a family from southern Italy with three brothers affected by early-onset parkinsonism, dementia, and amyotrophic lateral sclerosis. Molecular analysis of the DJ-1 gene in two living patients showed a novel homozygous mutation in exon 7 (E163K) and a new homozygous mutation (g.168_185dup) in the promoter region of the gene. Both mutations cosegregated with the disease and were detected in a heterozygous state in the patients' mother and their healthy siblings. Our findings expand the spectrum of clinical presentations associated with mutations in DJ-1 gene.
