We studied, by using the RNase protection technique, the expression of APP mRNAs in brains of Alzheimer's disease (AD) and other neurological disorders with special reference to aging.
Creutzfeld-Jacob disease and Gerstmann-Sträussler syndrome are rare degenerative disorders of the nervous system which have been genetically linked to the prion protein (PrP) gene.
Similarly, comparisons of DNA amplified from HTLV-1 DNA in cases of ATL, HAM, and TSP did not establish a correlation between the mutation in gp46 and neurological disease.
The Lesch-Nyhan (LN) syndrome is a genetically lethal human neurological disease that results from mutations that inactivate the hypoxanthine phosphoribosyltransferase (HPRT) gene.
Chronic and adult-onset GM2 gangliosidoses are neurological disorders caused by marked deficiency of the A isoenzyme of beta-hexosaminidase; they occur in the Ashkenazi Jewish population, though less frequently than classic (infantile) Tay-Sachs disease.
Complete deficiency of the purine salvage enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT) results in a devastating neurological disease, the Lesch-Nyhan syndrome.
Understanding of the molecular basis of paroxysmal disorders affecting the central nervous system has been revolutionalized with the identification of mutations in genes for the neurotransmitter receptors, GLRA1 and CHRNA4, and a voltage-gated potassium channel, KCNA1, as causes of inherited neurological disease.
We also measured the concentrations and activities of Cu/ZnSOD in FALS patients with no identifiable SOD1 mutations, sporadic ALS (SALS) patients, and patients with other neurologic disorders.
We found a consistent profile of increased TNF alpha and decreased IFN gamma and IL4 in all three syndromes compared to AIDS patients without neurological disease.
Hereditary hyperekplexia is a dominant neurological disorder associated with point mutations at the channel-forming segment M2 of the glycine receptor alpha 1 subunit.
Compound heterozygosity for metachromatic leukodystrophy and arylsulfatase A pseudodeficiency alleles is not associated with progressive neurological disease.
Dopa-responsive dystonia (DRD) is an autosomal-dominant neurological disorder which appears to result from a genetically determined deficiency of striatal dopamine.
Thus, a cardinal feature of POMA is the production of antibodies that inhibit Nova-1-RNA interactions, suggesting such inhibition may cause the neurological disease.
A number of human neurological disorders have been mapped to the Xp22 region, including Aicardi syndrome (MIM 304050), Rett syndrome (MIM 312750), X-linked Charcot-Marie-Tooth neuropathy (MIM 302801), and X-linked mental retardation syndromes (MRX1, MIM 309530).
Lesch-Nyhan (LN) disease is a severe X-linked recessive neurological disorder associated with a loss of hypoxanthine guanine phosphoribosyltransferase activity (HPRT, EC 2.4.2.8).
These results suggest that the intron 4 splice donor mutation likely produces some, at least partially functional, XPA protein that accounts for the increased UV survival of XP-A cell lines derived from patients with delayed onset of neurological disease.
