BACKGROUND Dysfunction of gamma-aminobutyric acid (GABA) (B) receptors has been implicated in the pathogenesis of temporal lobe epilepsy (TLE). OBJECTIVE To evaluate the genetic contribution of cloned human GABA(B) receptors to TLE. METHODS The authors genotyped 141 patients (78 women and 63 men; mean age = 49.1 +/- 18.0 years) with nonlesional TLE and(More)
OBJECTIVE To investigate whether polymorphisms in the genes for dopamine receptors D1 and D2 are associated with the risk of developing peak-dose dyskinesias in PD. BACKGROUND Peak-dose dyskinesias are the most common side effects of levodopa therapy for PD. The identified predictors may only partially account for the risk of developing peak-dose(More)
Cognitive impairment may occur at any time during the course of multiple sclerosis (MS), and it is often a major cause of disability in patients with the disease. The APOE-ε4 allele is the major known genetic risk factor for late onset familial and sporadic Alzheimer’s Disease (AD), and it seems to be implicated in cognitive decline in normal elderly(More)
To investigate the association between apolipoprotein E (APOE) polymorphisms and the progression of MS. We investigated 428 subjects affected by clinically defined MS, with a disease duration of at least three years. We collected data concerning the age at onset of MS, clinical type, disease duration and disability according to the expanded disability(More)
We re-evaluated the association with multiple sclerosis (MS) of the C77G splicing regulatory variation in the CD45 gene and screened for new mutations the three alternatively spliced exons (#4, 5 and 6). No association with C77G was detected in two groups of patients (total=448) and controls (total=559) from Northern and Southern Italy. When excluding the(More)
OBJECTIVES The APOE gene polymorphism and the -491 A/T polymorphism in its regulatory region have been associated with an increased risk for developing Alzheimer's disease. We examined these polymorphisms in multiple sclerosis (MS) patients, to determine if a genetic predisposition may explain the risk for developing cognitive decline in MS. MATERIAL AND(More)
Although multiple sclerosis (MS) is considered to be an inflammatory demyelinating disease, increasing evidence indicates that it is also an axonal pathology; indeed, studies of experimental allergic encephalitis showed that several neuronal proteins such as synapsins take part in the pathogenesis of the axonal dysfunction. Synapsins are a family of(More)
Caspase-9 is a primary effector CASP that executes programmed cell death, which plays an important role in the development of multiple sclerosis (MS). Polymorphisms in the CASP-9 gene may influence its activity, thereby modulating the susceptibility to MS. To test this hypothesis, we evaluated a SNP in the CASP-9 gene in a set of Italian patients from(More)
BACKGROUND The genes encoding myeloperoxidase (MPO) and alpha(2)-macroglobulin (A2M) are involved in molecular pathways leading to beta-amyloid deposition. Two polymorphic sites in these genes (MPO-G/A and A2M-Ile/Val) have been associated with Alzheimer disease (AD), but conflicting findings have been reported in populations with different ethnic(More)
