BACKGROUND Peptidyl-prolyl isomerase, NIMA-interacting 1 (PIN1) plays a significant role in the brain and is implicated in numerous cellular processes related to Alzheimer's disease (AD) and other neurodegenerative conditions. There are confounding results concerning PIN1 activity in AD brains. Also PIN1 genetic variation was inconsistently associated with(More)
Frontotemporal lobar degeneration (FTLD) with mutations in the MAPT (microtubule-associated protein tau) gene (FTLD with MAPT mutation) is a neurodegenerative disease with various clinical phenotypes. We present an Italian- Polish family with a IVS10+3G>A mutation in the MAPT gene, linked with haplotype H1s in a male proband (Fig. 2, II.2, H1s/H1b(More)
Over two dozen mutations in the gene encoding the microtubule associated protein tau cause a variety of neurodegenerative dementias known as tauopathies, including frontotemporal dementia (FTD), PSP, CBD and Pick's disease. The vast majority of these mutations map to the C-terminal region of tau possessing microtubule assembly and microtubule dynamics(More)
OBJECTIVES Patients with frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17) may be agraphic. The study aimed at characterizing agraphia in individuals with a P301L MAPT mutation. METHODS Two pairs of siblings with FTDP-17 were longitudinally examined for agraphia in relation to language and cognitive deficits. RESULTS All(More)
Interactions of transcriptions factors Nurr1, Pitx3, and EN1 are involved in the maturation and survival of adult midbrain dopaminergic neurons during a lifetime. The aim of the study was to evaluate the presence of mutations and single nucleotide polymorphisms in PITX3 gene in clinically diagnosed multisystem atrophy (MSA), progressive supranuclear palsy(More)
BACKGROUND Gilles de la Tourette syndrome (GTS) is a neurodevelopmental disorder characterized by motor and vocal tics. Hyperactivity of dopaminergic transmission is considered a prime abnormality in the pathophysiology of tics. There are reciprocal antagonistic interactions between adenosine and dopamine transmission. The aim of the study was to analyze(More)
Centronuclear myopathies constitute a group of heterogeneous congenital myopathies characterized by the presence of abnormal, centrally located nuclei within muscle fibers. Centronuclear myopathies can be caused by mutations of several different genes, including DNM2, encoding dynamin 2 (DNM2) a large GTPase involved in membrane trafficking and endocytosis.(More)
Frontotemporal dementia and parkinsonism linked to chromosome 17 is a rare variant of frontotemporal dementia, characterized by behavioral, cognitive and motor dysfunctions. The onset of the disease is variable. However, cognitive and behavioral changes usually precede motor symptoms. Early Background:
Olfactory dysfunction is associated with normal aging, multiple neurodegenerative disorders, including Parkinson's disease, Lewy body disease and Alzheimer's disease, and other diseases such as diabetes, sleep apnea and the autoimmune disease myasthenia gravis. The wide spectrum of neurodegenerative disorders associated with olfactory dysfunction suggests(More)
Gilles de la Tourette syndrome (GTS) is a neurodevelopmental disorder characterized by motor and vocal tics. The etiology of the disorder is unknown, although the predominant role of genetic factors has been established. Variants of the BTBD9 gene (rs4714156, rs9296249 and rs9357271) have been reported to be associated with GTS in French Canadian and(More)
