Histopathological and immunohistochemical examination of the brain for HIV-1 p24 antigen was performed in 50 HIV-infected patients with neurological symptoms; patients were defined as having HIV encephalitis in the presence of HIV-related lesions or HIV-1 p24 antigen-positive cells.
To investigate whether the expansion of CAG repeats of the TATA-binding protein (TBP) gene is involved in the pathogenesis of neurodegenerative diseases, we have screened 118 patients with various forms of neurological disease and identified a sporadic-onset patient with unique neurologic symptoms consisting of ataxia and intellectual deterioration associated with de novo expansion of the CAG repeat of the TBP gene.
Megaloblastic anaemia 1 (MGA1, OMIM 261100) is a rare, autosomal recessive disorder characterized by juvenile megaloblastic anaemia, as well as neurological symptoms that may be the only manifestations.
Several cellular and animal models for HD have revealed that intranuclear accumulation of mutant huntingtin and the formation of neuropil aggregates precede neurological symptoms and neurodegeneration.
We have determined the molecular basis of hypoxanthine-guanine phosphoribosyltransferase (HPRT; HPRT1) deficiency in eight Lesch-Nyhan patients and in five partially HPRT deficient patients with mild to severe neurologic symptoms.
Patients with alpha-tocopherol transfer protein (alpha-TTP) defects experience neurological symptoms characteristic of vitamin E deficiency and depend on continuous high alpha-tocopherol supplements.
Bone marrow stem cell gene therapy in mice, using a retroviral vector mediating expression of wild-type human ASA, has the potential to ameliorate the visceral pathology, but improves the prevailing brain disease and neurologic symptoms only marginally.
Plasma IL-6 was elevated in pSS patients compared with healthy controls. pSS patients with coeliac disease, pulmonary fibrosis or alveolitis or peripheral nervous system symptoms had significantly higher IL-6 levels than patients without these manifestations.
An inherited deficiency in beta-galactosidase can result in GM1 gangliosidosis, with several phenotypes of generalized or chronic psychomotor deterioration, as well as in Morquio disease type B, a characteristic mucopolysaccharidosis free ofneurological symptoms.
No significant difference was found in GS activity between patients with or without neurologic symptoms or in erythrocyte or fibroblast glutathione levels.
The pathogenicity of the novel mycobacterium and its clinical significance are not certain, as the neurological symptoms of the patient could also be due to concomitant infection with Cryptococcus neoformans.The name Mycobacterium doricum sp. nov. is proposed for the novel mycobacterium; the type strain is strain FI-13295T (= DSM 44339T = CIP 106867T).

Most of these findings were consistent with the newly established autosomal recessive disease "aceruloplasminaemia", except for the presence of serum Cp and the lack of apparent neurological symptoms.
To gain a better understanding of how mutations of the prion protein (PrP) gene are responsible for progressive dementia syndrome and to clarify the correlation between genotype and phenotype, which should help to explain how the prion promotes neurological symptoms.
Sjögren-Larsson syndrome is a rare disorder that consists of congenital ichthyosis and neurological symptoms due to an enzymatic defect of fatty aldehyde dehydrogenase in the fatty alcohol cycle.
These observations agree with earlier studies demonstrating that XPG mutations, which are predicted to lead to severely truncated proteins in both alleles, were associated with severe xeroderma pigmentosum/Cockayne syndrome neurologic symptoms.
