Abstract
BACKGROUND AND PURPOSE Heterozygous mutations in the STUB1 gene have recently been associated with an autosomal dominant form of spinocerebellar ataxia (SCA) associated with cerebellar cognitive-affective syndrome (CCAS), named SCA48. METHODS Molecular screening was performed in a cohort of 235 unrelated patients with adult-onset, autosomal dominant (17) or sporadic (218) cerebellar ataxia, negative for pathological trinucleotide expansions in the common SCAs, FRDA and FXTAS loci, by using targeted multigene panels or whole-exome sequencing. Bioinformatics analyses, detailed neurological phenotyping and family segregation studies corroborated the pathogenicity of the novel STUB1 mutations. Clinico-diagnostic findings were reviewed to define the phenotypic spectrum. RESULTS Eight heterozygous STUB1 mutations were identified, six of which were novel in 11 patients from eight index families, giving an estimated overall frequency of 3.4% (8/235) for SCA48 in our study cohort, rising to 23.5% (4/17) when considering only familial cases. All our SCA48 patients had cerebellar ataxia and dysarthria associated with cerebellar atrophy on brain magnetic resonance imaging; of note, many cases were also associated with parkinsonism, chorea and dystonia. CCAS also occurred frequently, whereas definite signs of pyramidal tract dysfunction and peripheral nervous system involvement were absent. One SCA48 patient presented with hypogonadism, associated with other autoimmune endocrine dysfunctions. CONCLUSIONS Our results support SCA48 as a significant cause of adult-onset SCA. Besides CCAS, our SCA48 patients often showed movement disorders and other clinical manifestations previously described in SCAR16, linked to biallelic variants in the same gene, thus suggesting a continuous clinical spectrum and significant overlap amongst recessive and dominantly inherited mutations in STUB1.

Abstract
BACKGROUND AND PURPOSE Hereditary ataxias are heterogeneous groups of neurodegenerative disorders, characterized by cerebellar syndromes associated with dysarthria, oculomotor and corticospinal signs, neuropathy and cognitive impairment. Recent reports have suggested mutations in the SPG7 gene, causing the most common form of autosomal recessive spastic paraplegia (MIM#607259), as a main cause of ataxias. The majority of described patients were homozygotes or compound heterozygotes for the c.1529C>T (p.Ala510Val) change. We screened a cohort of 895 Italian patients with ataxia for p.Ala510Val in order to define the prevalence and genotype-phenotype correlation of this variant. METHODS We set up a rapid assay for c.1529C>T using restriction enzyme analysis after polymerase chain reaction amplification. We confirmed the diagnosis with Sanger sequencing. RESULTS We identified eight homozygotes and 13 compound heterozygotes, including two novel variants affecting splicing. Mutated patients showed a pure cerebellar ataxia at onset, evolving in mild spastic ataxia (alternatively) associated with dysarthria (~80% of patients), urinary urgency (~30%) and pyramidal signs (~70%). Comparing homozygotes and compound heterozygotes, we noted a difference in age at onset and Scale for the Assessment and Rating of Ataxia score between the two groups, supporting an earlier and more severe phenotype in compound heterozygotes versus homozygotes. CONCLUSIONS The SPG7 c.1529C>T (p.Ala510Val) mutants accounted for 2.3% of cerebellar ataxia cases in Italy, suggesting that this variant should be considered as a priority test in the presence of late-onset pure ataxia. Moreover, the heterozygous/homozygous genotype appeared to predict the onset of clinical manifestation and disease progression.

Abstract
BACKGROUND Autosomal recessive (AR) spastic paraplegia type 5 (SPG5) is due to mutations in the CYP7B1 gene, encoding for the cytochrome P450-7B1, responsible for oxysterols 7α-hydroxylation. Oxysterol/cholestenoic acids pool plays a role in motor neuron survival and immune response. SPG5 is characterized by white matter abnormalities at brain resonance imaging (MRI). In view of clinical presentation and MRI findings, multiple sclerosis (MS) is a possible differential diagnosis of SPG5. This study aimed to evaluate the frequency of CYP7B1 mutations in patients with MS. METHODS One hundred and seventeen MS patients with clinical spastic paraplegia or possible AR transmission were selected for the mutational screening. RESULTS Forty-three patients had primary progressive, 26 relapsing remitting, 26 secondary progressive, and 22 relapsing progressive MS clinical course. No CYP7B1 homozygous mutations were identified. Two novel variants and one pathogenic mutation were found at heterozygous state. CONCLUSIONS The two novel variants cosegregated with pyramidal signs and autoimmune diseases suggesting that they might be susceptibility factors. Reduced cytochrome P450-7B1 enzymatic activity could alter the balance among neurotoxic and neuroprotective oxysterols promoting motor neuron degeneration and/or immune response.

Abstract
INTRODUCTION PARK20 is a rare autosomal recessive parkinsonism related to the SYNJ1 gene and characterized by early-onset of disease and atypical signs such as supranuclear vertical gaze palsy, dementia, dystonia, and generalized tonic-clonic seizures. OBJECTIVE Non-motor features and cardiac sympathetic innervation were assessed in two siblings affected by parkinsonism who harboured the homozygous Arg258Gln mutation in the SYNJ1 gene. METHODS The Non-Motor Symptoms, the SCOPA-AUT, the Mayo Sleep Questionnaires and polysomnography were used to investigate non-motor signs (NMS), autonomic dysfunction and REM Behavioural Disorder (RBD). Cognitive functions were examined by an extensive battery of neuropsychological tests. In addition, motor and sensory nerve conduction studies and evoked laser potentials were performed. Cardiac sympathetic innervation was assessed in the two patients by (123)I-metaiodobenzylguanidine (MIBG) scintigraphy, computing early and late heart-to-mediastinum (H/M) ratios and myocardial washout rates (WR). RESULTS Among the non-motor symptoms and autonomic signs, case 1 had cold intolerance, drooling and dysphagia, while case 2 had pain and urinary dysfunction. Both cases showed mood and behavioural disorders. RBD were not found, whereas the neuropsychological assessment revealed a progressive cognitive impairment. Neurophysiological studies revealed no abnormalities. Indexes of cardiac sympathetic innervation in the two patients did not differ from those of control subjects. CONCLUSIONS Our findings expand the phenotypic profile of SYNJ1-related parkinsonism. Preserved cardiac sympathetic function and absence of RBD suggest that PARK20 should be explained by a pathogenic mechanism different from Lewy Body pathology, or that the latter is not as widespread as idiopathic Parkinson's disease.

Abstract
Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a neurodegenerative disease due to mutations in SACS, which encodes sacsin, a protein localized on the mitochondrial surface and possibly involved in mitochondrial dynamics. In view of the possible mitochondrial involvement of sacsin, we investigated mitochondrial activity at functional and molecular level in skin fibroblasts obtained from ARSACS patients. We observed remarkable bioenergetic damage in ARSACS cells, as indicated by reduced basal, adenosine triphosphate (ATP)-linked and maximal mitochondrial respiration rate, and by reduced respiratory chain activities and mitochondrial ATP synthesis. These phenomena were associated with increased reactive oxygen species production and oxidative nuclear DNA damage. Our results suggest that loss of sacsin is associated with oxidative stress and mitochondrial dysfunction, and thus highlight a novel mechanism in the pathogenesis of ARSACS. The involvement of mitochondria and oxidative stress in disease pathogenesis has been described in a number of other neurodegenerative diseases. Therefore, on the basis of our findings, which suggest a potential therapeutic role for antioxidant agents, ARSACS seems to fall within a larger group of disorders.

Abstract
ABSTRACT:Background:The cervico-oculo-acoustic syndrome comprises Klippel-Feil anomaly, sensorineural deafness and Duane's retraction syndrome. Polygenic, autosomal dominant, and X-linked inheritance have been hypothesized. The disorder has rarely been reported in males.Case Report:A 42-year-old male, born of consanguineous parents, presented with Duane's syndrome, mixed hearing loss, C2-C3 fusion, neck stiffness, and right facial palsy. A variety of cardiac, neurological and urogenital anomalies occurred in his relatives. The electro-oculographic studies showed impaired abduction and adduction of the right eye and impaired abduction of the left eye. Vergence, vertical eye movements and peripheral vestibular responses were normal. Somatosensory evoked potentials showed absence of the N13 peak and brainstem auditory evoked potentials bilateral delay of the I-III interpeak latencies.Conclusions:Consanguinity of the patient's parents, not previously reported, suggests autosomal recessive inheritance, but autosomal dominant inheritance is indicated by the family history. The pattern of the oculomotor deficit is consistent with bilateral dysplasia of the abducens nuclei with preserved internuclear neurons in the right abducens nucleus. Neurophysiological investigations revealed lower brainstem and cervical cord involvement.

Abstract
BACKGROUND AND PURPOSE Apathy may be either a symptom of major depression or a behavioral disturbance occurring in concomitance with depression or alone in Parkinson's disease (PD). The aim of the present study was to determine the progression of cognitive impairment in drug-naïve untreated PD patients with or without clinically significant apathy. METHODS Sixty-two PD patients with a disease duration <2 years and without history of present or past therapy with pro-dopaminergic agents were included and underwent the Apathy Evaluation Scale (S-AES), a clinical interview based on diagnostic criteria for apathy and a comprehensive neuropsychological battery to assess memory, frontal functions and visuospatial functions. Two years after the first assessment, all patients were re-evaluated on the S-AES, a clinical interview and neuropsychological tests. RESULTS According to the cut-off value of the S-AES and diagnostic criteria for apathy, eight patients experienced apathy at both baseline and follow-up (A+A+), nine patients had apathy only at follow-up (A-A+), 37 patients never experienced apathy (A-A-) and eight patients showed apathy at the baseline only (A+A-). Cognitive performance significantly declined in all four groups. At both baseline and follow-up A+A+ performed worse than A-A- on visuospatial and frontal tests; A-A+ had lower scores than A-A- on the interference task of the Stroop test (IT-ST). Regression analysis showed that poor performance on the IT-ST at baseline was the only independent predictor of onset of apathy at follow-up. CONCLUSIONS The results indicated a relationship between apathy and dysexecutive syndrome in early PD. Reduced scores on the IT-ST may predict development of apathy in PD patients.

Abstract
OBJECTIVE To characterize brain metabolic changes associated with mild cognitive impairment (MCI) in drug-naive patients with Parkinson disease (PD) using (18)F-fluorodeoxyglucose (FDG) and PET (FDG-PET). METHODS This cross-sectional study included newly diagnosed patients with PD with MCI in single or multiple domain (PD-MCI; n =12) and without MCI (PD-nMCI; n =12), and healthy controls (n =12). The groups were matched for age. Moreover, the patient groups were matched for motor disability. All subjects underwent a FDG-PET study. Cerebral regional relative metabolic maps were compared in PD-MCI, PD-nMCI, and controls using regions of interest analysis (ROIs) and voxel-based analysis with statistical parametric mapping. RESULTS ROIs and voxel-based analyses revealed significant relative hypometabolism in the prefrontal, superior/inferior parietal, and associative occipital cortices as well as in the striatum in patients with PD-MCI relative to controls (p < 0.05) and to a lesser extent in patients with PD-nMCI. In contrast, patients with PD-nMCI did not show significant metabolic changes as compared to controls. CONCLUSION MCI in patients with PD is associated with cortical hypometabolism since the earliest stage, independent of therapy or motor disability. The early involvement of posterior cortical region, a pattern shared by advanced stages of PD-MCI and PD with dementia, could represent an early marker of dementia. The relevance of this pattern in predicting prodromal dementia has to be evaluated in longitudinal studies.

Abstract
Different lines of evidence suggest that higher intake of fiber may somehow protect against metabolic syndrome. The prebiotic inulin has widely been studied in relation to its putative beneficial effects on lipid and glucose metabolism. Therefore, adding inulin to diet may be a suitable strategy to prevent metabolic syndrome. Aim of the present study was to evaluate the effects of the daily consumption of inulin-enriched pasta on lipid and glucose metabolism as well as on gastrointestinal motility in young healthy subjects. Methods. Twenty-two healthy young male volunteers entered a randomized double blind cross-over study consisting of a 2-weeks a run-in period, two 5-weeks study periods (11% inulin-enriched or control pasta), and an 8-weeks wash-out period in between. Serum lipid and glucose concentrations were evaluated by routine biochemical analyses. Gastric emptying time and electrical activity were non-invasively evaluated by ultrasound and electrogastrography. Data were analyzed by Friedman Repeated Measures ANOVA test. Results. Significant differences among baseline and the treatment group were found for HDL-cholesterol (p=0.004), total cholesterol/HDL-cholesterol ratio (p=0.006), triglycerides (p=0.04), fasting glucose level (p=0.044), fructosamine (p=0.0478), HbA1c (p=0.04), and homeostatic model assessment (HOMA-IR) (p=0.045). The gastric emptying, expressed as final emptying time, was found significantly delayed in the group that assumed inulin-enriched pasta (p=0.008). Conclusions. Inulin-enriched pasta improved lipidic and glicidic metabolism as well as the insulin resistance in healthy young subjects. In addition, it delayed the gastric emptying time which may represent the physiological counterpart of its metabolic effects.

Abstract
Left ventricular hypertrophy (LVH) is a frequent finding in Friedreich's ataxia (FRDA). In previous studies treatment with idebenone, a synthetic analogue of coenzyme Q10, has been associated with a substantial decrease in myocardial hypertrophy, despite great variability in cardiac responsiveness among patients. Here we present the results of a retrospective analysis of a cohort of 35 patients (20 with LVH, 15 without LVH) with confirmed molecular diagnosis of FRDA, treated with idebenone 5 mg/kg/day for up to five years. At the end of the study, we found an increase of interventricular septum and posterior wall thickness in the group without LVH before treatment and no change in the group with LVH before treatment. The neurological picture of the disease significantly deteriorated with time in both groups.

Abstract
BACKGROUND Although heart involvement has been widely reported in Friedreich's ataxia (FA), which is the most prevalent of the spino-cerebellar degenerative diseases, the reason that cardiac abnormalities develop has not been yet established. HYPOTHESIS The investigation was undertaken to study the prevalence and characteristics of cardiac abnormalities in patients with FA and to evaluate whether the presence of left ventricular hypertrophy could be predicted. METHODS In all, 75 patients with FA and 16 patients with late onset FA (LOFA) disease were investigated for cardiac abnormalities using noninvasive methods. RESULTS A significant (p < 0.01) difference in the age onset (9.8 +/- 3.9 years) was found in 31 of the 75 patients with FA (41%) who showed left ventricular hypertrophy (LVH) at echocardiographic examination compared with the remaining 44 patients with FA without LVH (12.6 +/- 4.3 years). Moreover, none of the 16 patients with LOFA (age onset 26.5 +/- 4.2 years) showed abnormalities at echocardiographic examination. A significant (p < 0.01) concordance in the familial distribution of hypertrophy was also found. CONCLUSION These data suggest that the earlier the disease develops the more frequently LVH occurs.

Abstract
AIMS AND BACKGROUND Various genes have been identified for monogenic disorders resembling Parkinson's disease. The products of some of these genes are associated with mitochondria and have been implicated in cellular protection against oxidative damage. In the present study we analysed fibroblasts from a patient carrying the homozygous mutation p.W437X in the PTEN-induced kinase 1 (PINK1), which manifested a very early onset parkinsonism. RESULTS Patient's fibroblasts did not show variation in the mtDNA copy number or in the expression of the oxidative phosphorylation complexes. Sequence analysis of the patient's mtDNA presented two new missense mutations in the ND5 (m.12397A>G, p.T21A) and ND6 (m. 14319T>C, p.N119D) genes coding for two subunits of complex I. The two mutations were homoplasmic in both the patient and the patient's mother. Patient's fibroblasts resulted in enhanced constitutive production of the superoxide anion radical that was abrogated by inhibitor of the complex I. Moreover enzyme kinetic analysis of the NADH:ubiquinone oxidoreductase showed changes in the substrates affinity. CONCLUSION To our knowledge, this is the first report showing co-segregation of a Parkinson's disease related nuclear gene mutation with mtDNA mutation(s). Our observation might shed light on the clinical heterogeneity of the hereditary cases of Parkinson's disease, highlighting the hitherto unappreciated impact of coexisting mtDNA mutations in determining the development and the clinical course of the disease.

Abstract
The study of the role of glycemia in the causation of cardiovascular disease has been limited by several factors, above all by its measurement over time. Non enzymatic glycated proteins in the blood, the product of the non enzymatic reaction of a reducing sugar with the reactive amino acid of a target protein, are an integrated measure of blood glucose over days to weeks. They have been used in the management of clinical diabetes mellitus, but are still infrequently used in epidemiological studies in non diabetic subjects. There are few epidemiological studies that show that glycated hemoglobin, fructosamine, an index of total non enzymatic glycated proteins in the blood, and glycated apolipoprotein B and other non enzymatic glycated proteins in the blood in non diabetic subjects are associated with cardiovascular diseases. In this paper we review: 1) the overall mechanisms of non enzymatic glycation of proteins; 2) the measurement of glycated hemoglobin, fructosamine, and glycated apolipoprotein B and their relationship with blood glucose levels in non diabetic subjects; 3) the association of glycated hemoglobin, fructosamine and glycated apolipoprotein B with cardiovascular disease. We conclude that non enzymatic glycation of protein in the blood is associated with cardiovascular disease also in non diabetic subjects, and could be used to define dietary risk factors of cardiovascular disease.

Abstract
OBJECTIVE Neuropathological descriptions of the brain in Friedreich's ataxia (FRDA) were obtained before availability of the current molecular genetic tests for this disease. Voxel-based morphometry (VBM) enables an unbiased whole-brain quantitative analysis of differences in gray matter (GM) and white matter (WM) volume. METHODS Using VBM, we assessed the brain structural damage in 22 patients with genetically confirmed FRDA and 25 healthy controls. The results were correlated with the disease duration and the severity of the patients' clinical deficits--evaluated using the International Cerebellar Ataxia Rating Scale and Inherited Ataxia Clinical Rating Scale. RESULTS In patients with FRDA, VBM showed a symmetrical volume loss in dorsal medulla, infero-medial portions of the cerebellar hemispheres, the rostral vermis and in the dentate region. No volume loss in cerebral hemispheres was observed. The atrophy of the cerebellum and medulla correlated with the severity of the clinical deficit and disease duration. CONCLUSIONS In patients with FRDA, significant GM and WM loss was observed only in the cerebellum and dorsal medulla. These structural changes correlate with the severity of the clinical deficit and disease duration.

Abstract
Functional infrared imaging has been used to study 17 patients, affected by myofascial pain, and 19 healthy subjects during maximal voluntary clenching (MCV). Aim of the study was to attempt to discriminate patients from healthy subjects through the analysis of the skin temperature distribution and its change during the clenching. The prestress and the post-stress temperatures were evaluated bilaterally for several regions of interest. We calculated differences in temperature between sides (DeltaTs) at each time (pre and post), and between times (DeltaTt) for each side (left and right). Subsequently, we compared DeltaTs and DeltaTt between the healthy and myofascial pain groups. DeltaTs was significantly higher in sufferers compared to healthy people (p<0.05) for both types of evaluation (by side and by time). DeltaTs was significantly different for masseter and sternocleidomastoid, whereas DeltaTt was higher in almost all sites (masseter, sternocleidomastoid, cervical and upper trapezius). Healthy subjects, undergoing MVC, showed the lowest DeltaT value variability, suggesting that temperature remained constant despite the induced physical exercise. Functional infrared imaging seems to distinguish healthy subjects from the patients suffering myofascial pain in almost all the investigated sites.

Abstract
Skin temperature was monitored during a graded exercise to verify whether trained individuals have different skin thermoregulation from untrained ones. Eighteen subjects (10 trained; 8 untrained) were studied recording thermal videos of their skin temperature during the exercise. Training level was assessed by maximal oxygen uptake measurements. Trained individuals have better skin thermal control than untrained.

Abstract
AIMS To evaluate the association of serum concentrations of glycated apolipoprotein B (ApoBg) with the incidence of myocardial infarction (MI) in subjects with and without diabetes. METHODS The design is a nested case-control study. The cohort included 5632 subjects over 50 years of age attending the clinical laboratories of a small geographic area in southern Italy. After five years, 4563 subjects were traced and 103 had developed MI. We sampled from the cohort two controls for each incident case of MI, frequency matched for sex and diabetes. ApoBg was measured using a monoclonal antibody. Logistic regression was used for statistical analysis of the data. RESULTS ApoBg at baseline was higher in subjects who developed myocardial infarction than in controls in both non-diabetic and diabetic subjects (t test, P=0.009 and P=0.05 respectively). MI odds ratio in the third tertile of ApoBg was 2.01 (95% CI 0.93-4.33) in non-diabetic and 2.88 (0.85-9.68) in diabetic subjects (chi-square test for trend; non-diabetics P=0.03, diabetics P=0.06). Serum triglycerides, cholesterol, HDL and LDL cholesterol, glucose and insulin were not associated with MI (P>0.10). CONCLUSION ApoBg at baseline is directly associated with the development of MI in the following five years in both diabetic and non-diabetic individuals.

Abstract
Post-marketing surveillance studies are needed to assess the long-term safety, compliance and clinical efficacy of interferon beta-1a (IFNbeta-1a) therapy in multiple sclerosis (MS) patients. The goals of this study were to (i) assess the safety, compliance and clinical efficacy of long-term intramuscular (i.m.) IFNbeta-1a therapy in a large cohort of patients, and (ii) suggest possible predictors of therapeutic response. A total of 255 patients were included in the study. Mean time on therapy was 31.7 +/- 19.3 months. Within 3 years, 31% of patients discontinued treatment, mainly for disease activity. No significant sustained blood analysis alteration was observed over time, apart from a decrease of cholesterol levels. After 3 years of treatment, mean Expanded Disability Status Scale (EDSS) scores increased by 0.4 points compared with baseline. The mean annual relapse rate was reduced compared with baseline. Patients with < or = 2 relapses in the previous 2 years and with baseline EDSS scores of < or = 2 had a longer estimated time to first relapse and to progression and first relapse, respectively. These results confirm the safety and suggest a sustained effectiveness of i.m. IFNbeta-1a, extending the reported follow-up period to 6.3 years, and hypothesize the presence of possible predictors of clinical outcome.

Abstract
BACKGROUND Ataxia with oculomotor apraxia type 2 (AOA2) is characterized by onset between age 10 and 22 years, cerebellar atrophy, peripheral neuropathy, oculomotor apraxia (OMA), and elevated serum alpha-fetoprotein (AFP) levels. Recessive mutations in SETX have been described in AOA2 patients. OBJECTIVE To describe the clinical features of AOA2 and to identify the SETX mutations in 10 patients from four Italian families. METHODS The patients underwent clinical examination, routine laboratory tests, nerve conduction studies, sural nerve biopsy, and brain MRI. All were screened for SETX mutations. RESULTS All the patients had cerebellar features, including limb and truncal ataxia, and slurred speech. OMA was observed in two patients, extrapyramidal symptoms in two, and mental impairment in three. High serum AFP levels, motor and sensory axonal neuropathy, and marked cerebellar atrophy on MRI were detected in all the patients who underwent these examinations. Sural nerve biopsy revealed a severe depletion of large myelinated fibers in one patient, and both large and small myelinated fibers in another. Postmortem findings are also reported in one of the patients. Four different homozygous SETX mutations were found (a large-scale deletion, a missense change, a single-base deletion, and a splice-site mutation). CONCLUSIONS The clinical phenotype of oculomotor apraxia type 2 is fairly homogeneous, showing only subtle intrafamilial variability. OMA is an inconstant finding. The identification of new mutations expands the array of SETX variants, and the finding of a missense change outside the helicase domain suggests the existence of at least one more functional region in the N-terminus of senataxin.

Abstract
The authors performed a multimodal electrophysiologic evaluation in nine patients belonging to four SCA17 (spinocerebellar ataxia type 17) families. Peripheral nerve and visual system were not involved. Brainstem auditory evoked potentials were constantly abnormal with central type lesions. Magnetic motor evoked potentials were abnormal only in the lower limbs, suggesting a length-dependent involvement of the pyramidal tract. Somatosensory evoked potentials were abnormal in almost all our patients, and abnormalities were consistent with a somatosensory pathway involvement along the brainstem.

Abstract
BACKGROUND Parkinson's disease is a genetically complex disease with mixed mode of inheritance. Recently, a haplotype across the sepiapterin reductase (SPR) gene, which is located in the PARK3 linkage region, was shown to modulate age of onset of Parkinson's disease in sibships from North America. OBJECTIVE To make a thorough assessment of the SPR gene region in sporadic Parkinson's disease. METHODS A linkage study in 122 European sibship families with five microsatellite and 17 single nucleotide polymorphism (SNP) markers in and around the SPR gene region, and an association analysis in 340 sporadic cases of Parkinson's disease and 680 control subjects from Germany with 40 SNPs. Linkage was evaluated by non-parametric linkage scores and genotypic or haplotype association was tested by regression analysis, assuming different risk effect models. RESULTS Significant LOD scores between 2 and 3 were obtained at the two SPR-flanking markers D2S2110 and D2S1394 and seven SNP markers around the SPR gene. We found the previously reported promoter SNP rs1876487 also significantly associated with age of onset in our sib pair families (p-value 0.02). One strong linkage disequilibrium (LD) block of 45 kb including the entire SPR gene was observed. Within this LD block all 14 inter-correlated SNPs were significantly associated with Parkinson's disease affection status (p-value 0.004). CONCLUSIONS DNA polymorphisms in a highly intercorrelated LD block, which includes the SPR gene, appear to be associated with both sporadic and familial Parkinson's disease. This confirms a previous study showing that SPR potentially modulates the onset of or risk for Parkinson's disease.

Abstract
OBJECTIVE To undertake a full genome-wide screen for Parkinson's disease susceptibility loci. METHODS A genome-wide linkage study was undertaken in 227 affected sibling pairs from 199 pedigrees with Parkinson's disease. The pedigree sample consisted of 188 pedigrees from five European countries, and 11 from the USA. Individuals were genotyped for 391 microsatellite markers at approximately 10 cM intervals throughout the genome. Multipoint model-free affected sibling pair linkage analyses were carried out using the MLS (maximum LOD score) test. RESULTS There were six chromosomal regions with maximum MLS peaks of 1 or greater (pointwise p<0.018). Four of these chromosomal regions appear to be newly identified regions, and the highest MLS values were obtained on chromosomes 11q (MLS = 1.60, at 91 cM, D11S4175) and 7p (MLS = 1.51, at 5 cM, D7S531). The remaining two MLS peaks, on 2p11-q12 and 5q23, are consistent with excess sharing in regions reported by other studies. The highest MLS peak was observed on chromosome 2p11-q12 (MLS = 2.04, between markers D2S2216 and D2S160), within a relatively short distance (approximately 17 cM) from the PARK3 region. Although a stronger support of linkage to this region was observed in the late age of onset subgroup of families, these differences were not significant. The peak on 5q23 (MLS = 1.05, at 130 cM, D5S471) coincides with the region identified by three other genome scans. All peak locations fell within a 10 cM distance. CONCLUSIONS These stratified linkage analyses suggest linkage heterogeneity within the sample across the 2p11-q12 and 5q23 regions, with these two regions contributing independently to Parkinson's disease susceptibility.

Abstract
Ataxia with oculomotor apraxia type 1 (AOA1) is an autosomal recessive disorder characterized by early-onset cerebellar ataxia, oculomotor apraxia, and peripheral neuropathy. The causative gene (APTX) has been recently identified in Portuguese and Japanese kindreds. Three patients with AOA1 were identified in an APTX mutation screening on 28 Southern Italian patients with progressive ataxia and peripheral neuropathy. A novel homozygous missense mutation (H201Q) was found in one patient and a Japanese missense mutation (P206L) in two. AOA1 clinical heterogeneity and onset later than previously described are shown.

Abstract
OBJECTIVE To investigate whether the presence of parkin gene mutations is associated with different nigrostriatal impairment than other early-onset parkinsonism. METHODS Eighteen consecutive early-onset Parkinson disease (PD) patients (nine parkin and nine nonparkin patients) and six controls were studied with [123I]FP-CIT SPECT. RESULTS Parkin patients had longer disease duration (15 +/- 9 vs 6 +/- 2 years, p = 0.008) and higher Unified Parkinson's Disease Rating Scale (UPDRS) motor score (35.8 +/- 13.7 vs 22.8 +/- 7.9, p = 0.025) than nonparkin patients. Caudate and putamen DAT density were reduced by 60% and 79% in parkin and by 43% and 70% in nonparkin patients. Multiple regression analysis showed that the UPDRS and the presence of parkin gene mutations, but not the disease duration, were significantly correlated with the striatal DAT density. Parkin patients showed a more symmetric DAT loss in both caudate and putamen as compared with nonparkin patients. CONCLUSIONS Parkin-related disease may be associated with a higher degree of nigrostriatal impairment, independently of the clinical severity of the disease, and a more symmetric involvement as compared with non-parkin early-onset disease.
