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)
To investigate the role of the matrix metalloproteinase-9 gene (MMP-9) in multiple sclerosis (MS), we analyzed the functional -1562C/T and -90 (CA)(n) repeat polymorphisms in 243 Italian patients with MS and 173 healthy controls. A significant increase of the -1562T allele carriers was found in patients with MS compared to controls. Moreover, haplotype(More)
Estrogen receptor 1 gene polymorphisms (ESR1) have been found to be associated with multiple sclerosis (MS) in both Japanese and Finnish populations. We investigated the association between ESR1 polymorphisms (PvuII and XbaI) and MS in a study of 132 MS patients and 129 controls from the same geographic background (southern Italy). Allelic and genotypic(More)
BACKGROUND 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-epsilon4 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(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)
The authors investigated the segregation of two polymorphisms of the alpha2-macroglobulin gene (A2M-I/D and A2M-Ile1000Val) in patients with sporadic AD from southern Italy. The A2M-I and A2M-Val1000 alleles were more frequent in cases than in controls, and this effect was independent from the APOE-epsilon4 status as well as from the age at onset of AD.(More)
OBJECTIVE To investigate the association between apolipoprotein E (APOE) polymorphisms and the progression of MS. METHODS 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(More)
