Abstract
OBJECTIVE While several genes have been identified to cause Parkinson's disease (PD), monogenic forms explain only a small proportion of cases. We report clinical and genetic results in a large family with late-onset autosomal dominant PD. METHODS Thirty-eight family members of a five-generation Northern German PD family underwent a detailed neurologic examination, and transcranial sonography was performed in fifteen of them. Comprehensive mutation analysis of known PD-causing genes and a genome-wide linkage analysis were performed. RESULTS Late-onset definite PD was found in five subjects with a mean age at onset of 63 years. Another six individuals presented either with probable/possible PD or with subtle parkinsonian signs. Six members with a mean age of 79 years had an essential tremor phenotype. Mode of PD inheritance was compatible with autosomal dominant transmission. One of three examined patients with definite PD demonstrated an increased area of substantia nigra hyperechogenicity upon transcranial sonography. Comprehensive linkage and mutational analysis excluded mutations in known PD-causing genes. Genome-wide linkage analysis suggested a putative disease gene in an 11.3-Mb region on chromosome 7p15-21.1 with a multipoint LOD score of 2.0. CONCLUSIONS The findings in this family further demonstrate genetic heterogeneity in familial autosomal dominant late-onset PD.

Abstract
The diabetes syndrome of the BB rat resembles human Type 1 (insulin-dependent) diabetes including the prevalence of autoantibodies to the 64 kDa Beta-cell autoantigen, which has been identified as glutamate decarboxylase. This study aimed at detecting the prevalence and level of glutamate decarboxylase autoantibodies in 120-day-old diabetic and non-diabetic diabetes-prone BB/OK rats compared to those of sex- and age-matched diabetes-resistant LEW.1A rats. The antibodies were detected using semipurified glutamate decarboxylase from rat brain in two immunoassays, a direct and a sandwich enzyme-linked immunosorbent assay. For the last assay autoantibody-containing immunoglobulins of a serum from a patient with the stiff-man syndrome were used to bind specifically the enzyme as autoantigen in plastic wells. The antibody levels measured as optical density at 490 nm (x +/- SD)/prevalence of the diabetic group (120 +/- 29 days of age) of BB/OK rats 0.57 +/- 0.29 (n = 51)/88% as well as those of the nondiabetic group (121 +/- 26 days of age) with 0.51 +/- 0.29 (n = 32)/97% was significantly increased (p < 0.01) compared to those of the diabetes-resistant control group 0.15 +/- 0.06 (n = 29)/0%. Furthermore in a 209 +/- 27-day-old group (n = 21) of non-diabetic but diabetes-prone BB/OK rats the autoantibody levels of 1.21 +/- 0.39 vs 0.51 +/- 0.26 were further significantly enhanced (p < 0.01). These results were confirmed by a sandwich assay.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Gait disorders lead to loss of mobility and therefore of an individual's autonomy. The greatest risk factor for gait disorders is old age. Other important factors include drugs and their side effects, cognitive impairment, and alcohol abuse. In successful aging there is only a slight decline in gait velocity. The classification into lower- (peripheral), middle- (spinal, basal ganglia), and higher-level gait disorders (e.g. frontal or psychogenic) is still common but contradictory. Gait disorders in neurology are frequent. Detailed descriptions of gait patterns in hypokinetic gait disorders, dystonic, hemi-, and paraparetic gait, ataxia, vestibular, neuromuscular, and psychogenic gait are given. Besides reduction of risk factors, improving the physical state (physiotherapy, sports), descriptions of walking aids, and the prevention of falls are extraordinarily important for the therapy of gait disorders.

Abstract
BACKGROUND Polymorphisms in the glutathione S-transferase pi gene (GSTP1), encoding GSTP1-1, a detoxification enzyme, may increase the risk of Parkinson disease (PD) with exposure to pesticides. Using the GenePD Study sample of familial PD cases, we explored whether GSTP1 polymorphisms were associated with the age at onset of PD symptoms and whether that relation was modified by exposure to herbicides. METHODS Seven single-nucleotide polymorphisms (SNPs) were genotyped and tested for association with PD onset age in men in three strata: no exposure to herbicides, residential exposure to herbicides, and occupational exposure to herbicides. Haplotypes were similarly evaluated in stratified analyses. RESULTS Three SNPs were associated with PD onset age in the group of men occupationally exposed to herbicides. Three additional SNPs had significant trends for the association of PD onset age across the herbicide exposure groups. Haplotype results also provided evidence that the relation between GSTP1 and onset age is modified by herbicide exposure. One haplotype was associated with an approximately 8-years-earlier onset in the occupationally exposed group and a 2.8-years-later onset in the nonexposed group. CONCLUSIONS Herbicide exposure may be an effect modifier of the relation between glutathione S-transferase pi gene polymorphisms and onset age in familial PD.

Abstract
Chorea (from the greek word "dance") is characterized by short, involuntary, irregular, nonrepetitive, adventitious muscular contractions. The resulting movements may occur abruptly at any part of the body, but may also spread from one body part to another. The most important condition showing chorea as its core symptom is Huntington's disease. It is inherited as an autosomal dominant trait. During its course it presents as an admixture of neurological and psychiatric features. Several rare neurodegenerative diseases and conditions of inborn errors of metabolism present with chorea mostly between childhood and adolescence. Among these, the paroxysmal choreoathetoses are important for the differential diagnosis of seizures and transitory ischaemic attacks later in life. In adults, symptomatic chorea may occur in many drug-induced, metabolic, infectious, immunological, toxic, and vascular conditions. In addition to the basic treatments of these illnesses there are selected drugs to provide satisfactory symptomatic relief from the abnormal movement.

Abstract
Brain-derived neurotrophic factor (BDNF) stimulates neuronal growth and protects nigral dopamine neurons in animal models of Parkinson disease (PD). Therefore, BDNF is a candidate gene for PD. The authors investigated five single-nucleotide polymorphisms in 597 cases of familial PD. Homozygosity for the rare allele of the functional BDNF G196A (Val66Met) variant was associated with a 5.3-year older onset age (p = 0.0001). These findings suggest that BDNF may influence PD onset age.

Abstract
The treatment of Parkinson's disease (PD) with l-DOPA leads to involuntary movements (dyskinesias). This 6-month observational study in three European countries in PD patients with various degrees of motor complications examined the effects of dyskinesias on the quality of life (QoL) of patients and health care costs. Retrospective and prospective health economic data were collected, and QoL of patients was measured using the Short Form-36 (SF-36) and the PD Quality of Life (PDQL) Scale. Regression analysis was used to estimate the adjusted effects of dyskinesias on QoL and costs, whilst accounting for the potentially confounding effects of disease progression, motor fluctuations and country. Increasing dyskinesia scores on either the Unified PD Rating Scale or the Goetz Dyskinesia Rating Scale were associated with significant reductions in QoL scores on the SF-36 and PDQL Scale. Increasing dyskinesia severity was also associated with increased depression scores on the Montgomery-Asberg Depression Rating Scale along with significant increases in health care costs. The effects of dyskinesia on QoL, depression and costs decreased but remained significant after adjustment for the confounding effects of disease progression and motor fluctuations. In conclusion, dyskinesias may adversely affect QoL and increase health care costs in patients with PD. Future studies should evaluate the potentially beneficial effects in terms of QoL and health care costs of strategies to delay the onset of, or the treatment of, dyskinesias.

Abstract
Parkinson's disease (PD) is a neurodegenerative disorder in which relatives of the probands are affected approximately 4 times as frequently as relatives of control subjects. Several genes have been implicated as genetic risk factors for PD. We investigated the presence of six reported genetic variations in the SCNA, NR4A2, and DJ-1 genes in 292 cases of familial Parkinson's disease from the GenePD study. None of the variants were found in the GenePD families. Our results suggest that other variants or genes account for the familial risk of PD within the GenePD study.

Abstract
Mutations in GTP cyclohydrolase I (GCHI) are found in 50 to 60% of cases with dopa-responsive dystonia (DRD). Heterozygous GCHI exon deletions, undetectable by sequencing, have recently been described in three DRD families. We tested 23 individuals with DRD for the different mutation types by conventional and quantitative PCR analyses and found mutations, including two large exon deletions, in 87%. The authors attribute this high mutation rate to rigorous inclusion criteria and comprehensive mutational analysis.

Abstract
BACKGROUND Most cases of early-onset primary torsion dystonia (PTD) are caused by the same three-base pair (bp) (GAG) deletion in the DYT1 gene. Exon rearrangements are a common mutation type in other genes and have not yet been tested for in DYT1. Several lines of evidence suggest a relationship of the DYT1 gene with Parkinson disease (PD). OBJECTIVE To investigate the frequency and type of DYT1 mutations and explore the associated phenotypes in a mixed movement disorders patient cohort and in controls. METHODS The authors screened 197 patients with dystonia (generalized: n = 5; focal/segmental: n = 126; myoclonus-dystonia: n = 34; neuroleptic-induced: n = 32), 435 with PD, and 42 with various other movement disorders, along with 812 healthy controls, for small deletions in exon 5 of DYT1 and tested for exon rearrangements by quantitative, duplex PCR in 51 GAG deletion-negative dystonia cases. RESULTS The GAG deletion was detected in five patients: three with early-onset PTD, one with generalized jerky or clonic dystonia, and one with generalized dystonia and additional features (developmental delay, pyramidal syndrome). A novel out-of-frame four-bp deletion (934_937delAGAG) in exon 5 of the DYT1 gene was found in a putatively healthy blood donor. No exon rearrangements were identified in DYT1. CONCLUSIONS In this mixed patient sample, the GAG deletion was rare and in two out of five cases associated with an unusual phenotype. In addition, a novel DYT1 truncating mutation of unknown clinical relevance was found in a putatively unaffected individual. DYT1 exon rearrangements, however, do not seem to be associated with PTD.

Abstract
Parkinsonian syndrome is a clinical diagnosis. The appropriate selection of the diagnostic and therapeutic regime and its continuous monitoring are tasks for the specialist. The observations of the familydoctor can provide important information when the clinical course does not develop as expected. For idiopathic parkinsonian syndrome a wide range of medicinal, surgical and physical treatments are available. Physiotherapeutic and, where indicated, ergotherapeutic measures should form a regular component of the prescribed treatment.

Abstract
BACKGROUND Mutations in the Parkin gene (PARK2) are the most commonly identified cause of recessively inherited early-onset Parkinson disease (EOPD) but account for only a portion of cases. DJ-1 (PARK7) was recently reported as a second gene associated with recessively inherited PD with a homozygous exon deletion and a homozygous point mutation in two families. METHODS To investigate the frequency of DJ-1 mutations, the authors performed mutational analysis of all six coding exons of DJ-1 in 100 EOPD patients. For the detection of exon rearrangements, the authors developed a quantitative duplex PCR assay. Denaturing high performance liquid chromatography analysis was used to screen for point mutations and small deletions. Further, Parkin analysis was performed as previously described. RESULTS The authors identified two carriers of single heterozygous loss-of-function DJ-1 mutations, including a heterozygous deletion of exons 5 to 7 and an 11-base pair deletion, removing the invariant donor splice site in intron 5. Interestingly, both DJ-1 mutations identified in this study were found in the heterozygous state only. The authors also detected a polymorphism (R98Q) in 1.5% of the chromosomes in both the patient and control group. In the same patient sample, 17 cases were detected with mutations in the Parkin gene. CONCLUSIONS Mutations in DJ-1 are less frequent than mutations in Parkin in EOPD patients but should be considered as a possible cause of EOPD. The effect of single heterozygous mutations in DJ-1 on the nigrostriatal system, as described for heterozygous changes in Parkin and PARK6, remains to be elucidated.

Abstract
OBJECTIVE To identify a haplotype influencing onset age for Parkinson's disease (PD) in the PARK3 region on chromosome 2p13. METHODS Single nucleotide polymorphisms (SNP) spanning 2.2 Mb and located in or near potential candidate genes were used to fine map the PARK3 region in 527 patients with familial PD, from 264 families. RESULTS TT homozygotes for rs1876487 (G/T) had a 7.4-year younger mean age at onset (p = 0.005) compared to patients with GT and GG genotypes. Furthermore, SNP flanking the sepiapterin reductase (7,8-dihydrobiopterin: NADP+ oxidoreductase) (SPR) gene, rs1876487 (p = 0.02) and rs1150500 (p = 0.04), were associated with younger onset age among persons who did not carry the 174 allele of D2S1394. The SPR gene is implicated in dopamine synthesis. Haplotype analysis of three SNP-rs2421095, rs1876487, rs1561244-revealed an association with onset age (p = 0.023) and a haplotype of A-T-G alleles was associated with younger onset for PD (p = 0.005). CONCLUSIONS A haplotype at the PARK3 locus, harboring the SPR gene, is associated with onset age of PD. This may suggest a role for the SPR gene in modifying the age at onset of PD.

Abstract
Groups of patients with Parkinson's disease (PD), striatonigral degeneration-type multiple system atrophy (MSA) or progressive supranuclear palsy (PSP) with motor disability stages II and III according to Hoehn and Yahr, and a healthy control group were compared using neuropsychological tests of executive functions. The results indicate that all three patient groups were impaired in the tests of executive functions. In comparison with healthy subjects, the three patient groups showed impaired performance regarding verbal fluency, problem solving and verbal and figural working memory. Patients with PD differed significantly from healthy subjects in a test of verbal recency, while patients with MSA or PSP were unimpaired. The comparison of patient groups revealed no differences between PD and MSA patients. However, patients with PSP showed greater impairment in both phonemic and semantic fluency than patients with PD or MSA. Using discriminant function analysis, it was found that variables derived from four verbal fluency tasks (simple and alternate semantic and phonemic fluency) discriminated among the three patient groups at a level significantly exceeding chance. Over 90% of patients with PSP were correctly classified. Patients with PD and MSA were correctly classified in over 70% of cases. These results suggest that verbal fluency tasks may be sensitive measures in the differential diagnosis of PD, MSA and PSP.

Abstract
Spinocerebellar ataxia type 4 (SCA4) is an autosomal dominant disorder mapped to chromosome 16q22.1 in a large Utah kindred. The clinical phenotype is characterized by cerebellar ataxia with sensory neuropathy. We describe a five-generation family from northern Germany with similar clinical findings linked to the same locus. Haplotype analyses refined the gene locus to a 3.69 cM interval between D16S3019 and D16S512. Analysis of nine CAG/CTG tracts in this region revealed no evidence for a repeat expansion.

Abstract
OBJECTIVES To determine the frequency of familial focal and segmental dystonias in a large patient cohort with primary dystonia from north-western Germany. MATERIALS AND METHODS In this study, 130 patients with focal or segmental dystonia were examined and a family history was obtained. Whenever possible, affected relatives were examined (a total of 789 first-degree relatives). Data on disease duration, age at disease onset and age of the patients were investigated by Student's t-test and a segregation analysis was performed by Weinberg's proband method. RESULTS Age at onset of disease was significantly later in the blepharospasm group. Only in the writer's cramp group were women outnumbered by men. A positive family history was found in 15 of the 130 index patients (11.5%). None of 102 index patients tested carried the GAG deletion in the DYT1 gene. CONCLUSIONS In accordance with previous series our study provides evidence that primary focal dystonia may have a genetic etiology, most probably caused by an autosomal dominant trait with reduced penetrance.

Abstract
Congenital disorders of glycosylation (CDG) are a group of hereditary multisystem diseases due to different defects of enzymes or transport molecules involved in the synthesis of glycoproteins. CDG-la is the most common subtype, with cerebellar ataxia as the main neurological symptom. Currently there is little information about CDG-la manifestation in adulthood. Here we present two sisters in whom the diagnosis of CDG-la was made in the fourth decade of life and who to our knowledge are the oldest known patients with the disorder in Germany. The clinical course of the disease was typical, although less severe than previously described. The carbohydrate-deficient transferrin (CDT) level was increased but lower than in other CDG patients. Isoelectric focusing of transferrin revealed changes typical of CDG, whereas those of alpha 1-antitrypsin were only moderately pathologic. This might be due to the milder manifestation of the disease in our patients or it could be indicative of a stabilization of the disease after puberty. The CDG should be included in the differential diagnostic workup of hereditary cerebellar ataxia in adults.

Abstract
Retrospective case-control studies among patients with idiopathic Parkinson's syndrome (IPS) show a positive association to the existence of a - mostly premorbid - exposure to pesticides. In acute pesticide intoxications, usually symptoms other than parkinsonism are found. Therefore, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) continues to be the agent best documented both experimentally and clinically to cause a clinical syndrome comparable to IPS. It is debated whether still unknown effects between exogenous pesticide exposure and the xenobiotic enzyme system may lead to IPS in single genetically susceptible individuals. In practice, the present data on the problem of pesticide exposure in IPS are irrelevant for medicolegal considerations.

Abstract
The authors describe a 37-year-old woman with early-onset hemiparkinsonism (HP) and ipsilateral body hemiatrophy (HA). Genetic analysis revealed a missense mutation (Arg275Trp) and a duplication of exon 7 of parkin. The complementary metabolic and receptor pattern of PET ligands corresponded to that typically found in idiopathic PD, although tracer binding asymmetry was lacking. Parkin mutations should be considered in HPHA, particularly when there is a younger age at onset and dystonia is an early sign.

Abstract
OBJECTIVE To examine patterns of familial aggregation and factors influencing onset age in a sample of siblings with PD. METHODS Sibling pairs (n = 203) with PD were collected as part of the GenePD study. Standardized family history, medical history, and risk factor data were collected and analyzed. RESULTS The mean age at onset was 61.4 years and did not differ according to sex, exposure to coffee, alcohol, or pesticides. Head trauma was associated with younger onset (p = 0.03) and multivitamin use with later onset (p = 0.007). Age at onset correlation between sibling pairs was significant (r = 0.56, p = 0.001) and was larger than the correlation in year of onset (r = 0.29). The mean difference in onset age between siblings was 8.7 years (range, 0 to 30 years). Female sex was associated with increased frequency of relatives with PD. The frequency of affected parents (7.0%) and siblings (5.1%) was increased when compared with frequency in spouses (2.0%). CONCLUSIONS The greater similarity for age at onset than for year of onset in sibling pairs with PD, together with increased risk for biological relatives over spouses of cases, supports a genetic component for PD. Risk to siblings in this series is increased over that seen in random series of PD cases; however, patients in this sample have similar ages at onset and sex distribution as seen for PD generally. These analyses suggest that factors influencing penetrance are critical to the understanding of this disease.

Abstract
BACKGROUND An inverse association between cigarette smoking and the risk of idiopathic PD has been found in many epidemiologic studies. The therapeutic and possible neuroprotective effects of nicotine formulations on parkinsonian symptoms are controversial. METHODS In a 12-week, randomized, double-blind, placebo-controlled trial, the efficacy and tolerability of transdermal nicotine patches as an add-on treatment for cardinal symptoms were evaluated in 32 nonsmoking patients with PD. After a 1-week run-in phase, patients were randomized to receive nicotine patches (containing 17.5 mg nicotine in the first and 35.0 mg nicotine in the second and third weeks) or identically appearing placebo patches. After this treatment, 3 weeks without patch application followed. The same blinded examiner assessed the patients with the Columbia University Rating Scale, the Webster scale, the Schwab-England scale, a timed walking test, with an instrumental test for fine motor skills and hand tremor, and with the Hamilton Depression Scale. RESULTS No significant drug effects between both groups were observed in any of the scores and quantitative tests. Side effects were mild and comparable in frequency between both groups. CONCLUSIONS With the dosage and the period of treatment chosen, transdermal nicotine patches are not effective as an add-on treatment for symptoms of PD.

Abstract
A genome-wide scan for idiopathic PD in a sample of 113 PD-affected sibling pairs is reported. Suggestive evidence for linkage was found for chromosomes 1 (214 cM, lod = 1.20), 9 (136 cM, lod = 1.30), 10 (88 cM, lod = 1.07), and 16 (114 cM, lod = 0.93). The chromosome 9 region overlaps the genes for dopamine beta-hydroxylase and torsion dystonia. Although no strong evidence for linkage was found for any locus, these results may be of value in comparison with similar studies by others.

Abstract
Early-onset parkinsonism (EOP) may be associated with different mutations in the parkin gene, including exon deletions and duplications. To test for gene dosage alterations, we developed a new method of quantitative duplex PCR using the fluorescence resonance energy transfer technique on the LightCycler (Roche Diagnostics). In 21 patients with EOP, three mutations (a single base pair substitution in exon 3 and small deletions in exon 9) were detected by conventional mutational screening (single-strand conformation polymorphism and sequence analysis), while alterations of gene dosage were found in seven patients. We identified heterozygous and compound heterozygous deletions of exons 2, 3, 5 and 7. The latter was also found in the homozygous state. In addition, two heterozygous duplications of exon 4 were observed. Remarkably, two patients carried more than two parkin mutations. This is the first study systematically screening all 12 exons of parkin by real-time, kinetic quantification and clearly shows that mutational analysis of the parkin gene should include gene dosage studies. Furthermore, our method of quantitative PCR is easily applicable to any other gene to be screened for deletions or duplications of whole exons.

Abstract
In a prospective series of 34 incident patients with primary cervical dystonia (CD), 6 showed clinical or radiological signs of cervical radiculopathy (RP) or myelopathy (MP) during the course of their movement disorder. Age at onset in these patients was in the range reported for pure spondylotic cervical RP without an accompanying movement disorder. Radiologically, spondylosis was mild in 1 case and absent in 2 cases. The intervals between onset of CD and RP were shorter than in literature reports of RP/MP in dystonic-athetotic patients of cerebral paresis. Clinically, RP/MP in patients with CD mostly appears at mid-cervical levels, whereas cases with cerebral paresis are more frequently affected at higher cervical segments. We propose that RP/MP does not occur more frequently in CD than in pure spondylotic cervical RP.

Abstract
OBJECTIVE To evaluate the opinions and attitudes of young patients with Parkinson's disease (PD) towards possible presymptomatic and prenatal genetic testing for their illness. BACKGROUND With progress in understanding of the genetic component in the etiology of PD, presymptomatic genetic testing may become available in subgroups of patients. METHODS During a survey on sociodemographic and risk factors 111 PD patients (mean age 45 years: mean age at PD onset 36 years) were given a questionnaire with six items about possible presymptomatic and prenatal genetic testing. RESULTS Fifty-seven patients (5196) had knowledge about presymptomatic and prenatal testing. Eighty patients (72%) would take a presymptomatic test, if they had an autosomal dominant form of PD and if the test were available. The most Important reasons given for taking the test were planning of partnership (40%) and family (48%). When being identified as a carrier of a presumed "Parkinson gene", 78 patients (70%) would decide not to have children. Sixty-three patients (57%) would choose to have prenatal testing. Attitudes were largely independent of sociodemographic and disease variables. CONCLUSIONS When addressed as hypothetical persons at genetic risk, young patients with PD support possible presymptomatic genetic testing and, to a lesser extent, prenatal testing. Attitudes and reasons to participate in such hypothetical testing do not grossly differ from those of at-risk persons in established single-gene autosomal dominant disorders of late onset.

Abstract
Dystonia is a movement disorder involving sustained muscle contractions and abnormal posturing with a strong hereditary predisposition and without a distinct neuropathology. In this study the TOR1A (DYT1) gene was screened for mutations in cases of early onset dystonia and early onset parkinsonism (EOP), which frequently presents with dystonic symptoms. In a screen of 40 patients, we identified three variations, none of which occurred in EOP patients. Two infrequent intronic single base pair (bp) changes of unknown consequences were found in a dystonia patient and the mother of an EOP patient. An 18-bp deletion (Phe323_Tyr328del) in the TOR1A gene was found in a patient with early onset dystonia and myoclonic features. This deletion would remove 6 amino acids close to the carboxy terminus, including a putative phosphorylation site of torsinA. This 18-bp deletion is the first additional mutation, beyond the GAG-deletion (Glu302/303del), to be found in the TOR1A gene, and is associated with a distinct type of early onset dystonia.

Abstract
A kindred from South Tyrol (northern Italy) with familial, adult-onset parkinsonism of pseudo-dominant inheritance and mutations in the parkin gene was recently described. To gain insight into basal ganglia dysfunction in this form of hereditary parkinsonism, positron emission tomography (PET) with 18-fluorodopa (FDOPA) and 11C-raclopride (RAC) was performed in 5 affected family members and 5 asymptomatic relatives with proven compound heterozygous or heterozygous parkin mutations. Results were compared to findings in healthy control subjects and patients with typical sporadic, idiopathic Parkinson's disease. Similar to findings in the sporadic Parkinson's disease group, presynaptic striatal FDOPA storage was decreased in patients with compound heterozygous parkin mutations, with the most prominent reduction in the posterior part of the putamen. Along with the presynaptic lowered FDOPA uptake, we found a uniform reduction of the striatal 11C-raclopride binding index in all affected family members as compared to asymptomatic family members carrying a heterozygous parkin mutation, sporadic Parkinson's disease, and control subjects. Our PET data provide evidence that parkinsonism in this family is associated with presynaptic dopaminergic dysfunction similar to idiopathic Parkinson's disease pathophysiology, along with alterations at the postsynaptic D2 receptor level. In asymptomatic carriers of a single parkin mutation with an apparently normal allele, we found a mild but statistically significant decrease of mean FDOPA uptake compared to control subjects in all striatal regions. These data indicate a preclinical disease process in these subjects.
