Abstract
The etiopathogenesis of eating disorders (ED) is complex and poorly understood. The hypothalamic-pituitary-adrenal (HPA) axis, involved in the biological response to stress, could influence the onset and the course of ED.) Several variants in the Glucocorticoid receptor (GR) gene have been related to different metabolic parameters suggesting a possible role in ED. We studied if genetic variants of GR could represent potential risk factors for the development of Anorexia Nervosa (AN) and Bulimia Nervosa (BN).We investigated the distribution of several single nucleotide polymorphisms (SNPs) of the GR including N363S (rs6195), Er22/23EK (rs6189-6190), A/G SNP in exon 9beta (rs6198) and the intronic BclI polymorphism (rs41423247), in 118 Italian patients affected by AN and in 108 patients with BN. Moreover we studied 116 normal individuals and 177 obese subjects. The distributions of genotypes and allele frequency of the SNPs in all studied groups followed Hardy-Weinberg equilibrium and did not significantly differ from that of controls. A trend towards association was observed in case-control association analysis (p=0.07) for rs6198. A correlation of metabolic parameters to the GR genotypes was performed.We report the analysis of different GR SNPs for the first time in Italian patients with AN and BN. We failed to detect an allelic association between the studied SNPs in the GR gene and AN and BN.None of the variants seems to influence these pathologies, not supporting a role for the GR gene as genetic risk factors for ED.

Abstract
SUMMARY Morphometry and spectroscopy were performed in 3 patients with fragile X-associated tremor/ataxia syndrome (FXTAS). The brain stem and cerebellum were atrophic and satisfied criteria for olivopontocerebellar atrophy in 2 patients. However, the vermis was relatively spared and the basis pontis maintained its oval shape. The only spectroscopic abnormality was a decrease of the pontine N-acetylaspartate/creatine ratio in 1 patient. Atrophy and metabolic changes in FXTAS differ to some extent from those of olivopontocerebellar atrophy.

Abstract
This study investigated the contribution that white matter changes (WMCs) make to clinical and cognitive features in Alzheimer's disease (AD), independently of possible confounders such as cortical atrophy and the apolipoprotein E genotype as well as their relationship to vascular risk factors. We semiquantitatively assessed the degree and location of WMCs (global, periventricular and deep white matter), lacunes and global atrophy on brain MRI scans of 86 AD cases, extensively evaluated from a clinical and neuropsychological point of view. Multivariate logistic and linear regression analysis showed that age was the only significant predictor of all WMC measures and revealed a significant association of periventricular WMCs with performance on executive function tasks as well as of deep WMCs with history of mood depression. Our results underline the significance of WMC location over size in the occurrence of specific cognitive deficits in AD.

Abstract
The high activity Val158 (H) allele of the dopamine-metabolizing enzyme catechol-O-methyltransferase (COMT) was associated with anorexia nervosa (AN) in a recent family trio-based study of patients from Israel. In an attempt to replicate this finding, we performed a combined family trio and case-control study in an European population from seven centers in six different countries (Austria, Germany, Great Britain, Italy [Milan], Italy [Florence], Slovenia, and Spain), together contributing a total of 372 family trios, 684 controls and 266 cases. TDT analyses of high (H) and low (L) alleles in family trios showed that H allele and L allele were each transmitted 101 times (chi(2) = 0, ns). Allele-wise case-control analysis using separate samples simply combined from the centers was also not significant, with the frequencies of the H allele 50% in cases and same in controls. Stratified analysis of data from all centers gave an odds ratio of 0.98 (Cornfield 95% confidence limits 0.78-1.24). Analysis by genotype was likewise not significant (overall chi(2) = 0.42). Because we were not able to support the primary hypothesis that Val158Met is a risk factor for AN, we did not perform secondary analysis of minimum body mass index (mBMI), age at onset or illness subtype (restricting or binge purging anorexia). Overall we found no support for the hypothesis that the Val158 allele of COMT gene is associated with AN in our combined European sample.

Abstract
This FDG-PET study with SPM99 compared 46 patients with sporadic Alzheimer disease (SAD) to 40 patients with familial AD (FAD) and to 35 matched controls. AD groups had equivalent metabolic (METglu) reductions in several cortical and limbic areas with respect to the controls. Patients with FAD showed decreased METglu in the posterior cingulate, parahippocampal, and occipital cortex as compared to the patients with SAD (p < 0.001). Genetic factors lead to phenotypic differences in AD.

Abstract
Several case-control association studies have raised the possibility that the A allele of a -1438 G/A polymorphism in the type 2A serotonin receptor (HTR2A) gene may be a risk factor for anorexia nervosa. However the absence of linkage and the existence of negative association studies raise the possibility of false positive findings, resulting from population stratification or lack of statistical power. To address this controversy we recruited a sample of 316 patients with anorexia nervosa from six European centres, and utilised a family-based transmission disequilibrium (TDT) approach to analyse the HTR2A-1438 G/A polymorphism. Age at onset and minimal BMI were also taken into consideration in order to detect clinical heterogeneity or a quantitative trait effect. The TDT approach showed that the A allele was transmitted 133 times and not transmitted 148 times (McNemar chi(2) = 0.29, df = 1, P = 0.59). Also, the haplotype-based haplotype relative risk method showed no evidence for association of the A allele, in samples from each centre (chi(2) < 2.15, df = 1, P > 0.14) and in the total sample (chi(2) = 0.55, df = 1; P = 0.46). Furthermore, we found no evidence for heterogeneity of the A allele frequency between samples (chi(2) = 2.54, df = 4, P = 0.64), either according to minimal-BMI (F1/242 = 2.14, P = 0.45) or age at onset (F1/224 = 2.39; P = 0.12). QTL-TDT analyses also showed no direct role of the A allele on these traits. We thus found no evidence for a significant role of the 5-HT(2A) gene in anorexia nervosa. Previous results may have been exposed to stratification bias (which we controlled by the TDT method) and/or the risk of type 1 error (from which we were less exposed because of the sample size).

Abstract
BACKGROUND The spinocerebellar ataxias (SCAs) are clinically heterogeneous disorders caused by triplet repeat expansions in the sequence of specific disease genes. Spinocerebellar ataxia type 8 (SCA8), originally described in a family characterized by pure cerebellar ataxia with slow disease progression, presents with expansion of combined CTA/CTG repeats. OBJECTIVE To perform SCA8 repeat expansion analysis in a heterogeneous group of ataxic patients, to determine the prevalence of this mutation in our patients and establish the frequency of expanded CTA/CTG repeats in a large group of control subjects. PATIENTS One hundred sixty-seven patients affected by sporadic, autosomal dominant and recessive hereditary ataxia were clinically examined and analyzed for SCA8 expansion. We further studied 161 control subjects and 125 patients with psychiatric disorders. RESULTS We found abnormally expanded CTA/CTG repeats in 5 ataxic patients, 3 of them characterized by pure cerebellar ataxia. One patient had vitamin E deficiency and 1 patient with a sporadic case was affected by gluten ataxia. No evidence of expanded alleles was found in healthy control subjects and in patients with psychiatric disorders. CONCLUSIONS Our data support the evidence that CTG expansions may be linked to SCA8, since the pathogenic expansions have been found only among patients with genetically unidentified forms of hereditary and sporadic ataxia. Patients carrying expanded alleles present peculiar phenotypic features, thus suggesting that unknown additional factors could probably predispose to the disease.

Abstract
In the last 10 years significant progress has been made to describe and identify the underlying biological mechanisms that cause the different manifestation of Alzheimer's disease. Since the first report of a possible locus on chromosome 21 in a small group of families with early onset familial Alzheimer's disease (FAD), considerable progress has been made. Results from linkage analysis and gene sequencing has provided evidence that a minority of early onset FAD families develops the disease as a result of mutations in the gene coding for the Abeta-amyloid precursor protein, and that mutations in presenilin 1 and 2 genes account for a larger subgroup of early onset families. Several other early onset FAD families are clearly not linked to any of these loci, suggesting that other genetic risk factors may exist. Recent genome-wide scanning studies have revealed the existence of a new locus on chromosome 12, which, together with inheritance of the epsilon4 allele of apolipoprotein E gene, on chromosome 19, represent the most important genetic factors associated with an increased risk of developing the disease in late onset FAD families.

Abstract
We have clinically and genetically evaluated 24 affected patients belonging to 22 Italian Friedreich ataxia (FA) families, 52 patients from 32 kindreds with proven autosomal dominant cerebellar ataxia (ADCA), 9 patients belonging to 5 families with autosomal recessive hereditary ataxia (ARCA) and 103 sporadic cases, 89 of which affected by idiopathic late onset cerebellar ataxia (ILOCA). Genotype-phenotype correlation analyses in FA patients have evidenced an inverse relationship between GAA repeat expansion length and age of onset, disease duration, and presence of cardiomyopathy. Among autosomal dominant types, spinocerebellar ataxia 2 (SCA2) genotype has been found in 31% of our ADCA families, resulting the most frequent form of ataxia. Phenotypic analysis of the various SCA subtypes evidenced a marked heterogeneity of symptoms with a substantial overlap between different syndromes.

Abstract
A 5-bp deletion and a Val1000 polymorphism at the alpha(2)-macroglobulin (A2M) gene have recently been reported to be associated with late onset Alzheimer's disease (AD). As recently it has been suggested that the effect of the A2M gene on AD susceptibility may be limited to certain populations or families, we analyzed the segregation of A2M and apolipoprotein E polymorphisms in Italian sporadic and familial AD. We analyzed the two polymorphisms in a total of 346 subjects including 98 controls by polymerase chain reaction-restriction fragment length polymorphism method. Our data do not confirm these associations, in particular we found a significant decrease of the deletion allele in AD with respect to controls. Our data do not support a role for the A2M gene as genetic risk factor for AD.

Abstract
The two acylphosphatase isoenzymes (muscle type and common type) are differently involved in cell differentiation processes. In this paper we investigate the expression of the two isoenzymes during macrophage differentiation and activation. The U-937 human promonocytic cell line is a model for cell differentiation induced by the tumor promoter phorbol myristic acetate (PMA). Here we show that only the expression of the muscle type acylphosphatase increases during U-937 differentiation and macrophage activation, confirming that the two isoenzymes are differently regulated. Moreover, we determined, in the same conditions, the level of specific mRNA. Results show that after an initial two-fold decrease during PMA stimulation, the muscle type acylphosphatase mRNA levels remain constant also after the treatment with lipopolysaccharide and gamma-interferon, treatments that lead to macrophage activation. It is possible that post-transcription regulation is responsible for the regulation of muscle type acylphosphatase in the cell during differentiation and macrophage activation.
