Evidence for linkage disequilibrium between the alpha 7-nicotinic receptor gene...
Xu, Junzhe; Pato, Michele T.; Torre, Camille Dalla; Medeiros, Helena; Carvalho, Célia; Basile, Vincenzo S.; Bauer, Amy; Dourado, Ana; Valente, JoséRecent studies have suggested that the alpha 7-nicotinic receptor gene (CHRNA7) may play a role in the pathogenesis of schizophrenia. The alpha 7-nicotinic receptor gene (CHRNA7) is involved in P50 auditory sensory gating deficits, and the genomic locus for this gene lies in the chromosome 15q13-14 regions. The human gene is partially duplicated (exons 5-10) with four novel upstream exons. The marker D15S1360 h...
Long repeat tracts at SCA8 in major psychosis
Vincent, John B.; Yuan, Qiu-Ping; Schalling, Martin; Adolfsson, R; Azevedo, M. Helena; Macedo, António; Bauer, Amy; DallaTorre, CamilleExpansion at a recently identified unstable trinucleotide repeat on chromosome 13q21 has been reported as the molecular cause for spinocerebellar ataxia type 8 (SCA8). The trinucleotide repeat, which consists of a [CTA]n repeat and adjacent [CTG]n repeat, was reported to have a pathogenic range of 107-127 CTG repeats (or 110-130 combined CTA and CTG repeats) in a large ataxia kindred. This repeat region was als...
