Evidence against linkage of schizophrenia to chromosome 5q11-q13 markers in systematically ascertained families.

1992

Ten pedigrees systematically ascertained in Germany were tested for linkage to chromosome 5q11-q13. In order to replicate the previous report by Sherrington et al (1988), families with a bipolar family member were omitted from the lod score calculations, all diagnoses were based upon Research Diagnostic Criteria, and four different models of the affection status were calculated, including the model for which Sherrington et al calculated the highest lod scores. None of the families investigated showed a positive lod score. Using multipoint linkage analyses, we were able to exclude the region for which a positive linkage has been reported.

Untersuchungen zur Kopplung zwischen Schizophrenie und der pseudoautosomalen Region

1993

Fur die Suche nach Genorten fur genetisch determinierte Erkrankungen mit Hilfe von Kopplungsanalysen werden zwei Strategien angewandt: 1. das systematische Absuchen des Genoms auf Kopplung von Genort mit Marker mit Hilfe von DNA-Markern (RFLP, Short Tandem Repeats) in regelmasigen Abstanden, 2. die Verwendung von DNA-Markern zur Kopplungsanalyse in Kandidatengenregionen, fur die ein Zusammenhang mit der Erkrankung angenommen wird, bei psychiatrischen Erkrankungen, z. B. Genorte fur Enzyme, Rezeptoren, Transporter fur Neurotransmitter.

Systematic screening for mutations in the promoter and the coding region of the 5-HT1A gene.

1995

In the present study we sought to identify genetic variation in the 5-HT{sub 1A} receptor gene which through alteration of protein function or level of expression might contribute to the genetic predisposition to neuropsychiatric diseases. Genomic DNA samples from 159 unrelated subjects (including 45 schizophrenic, 46 bipolar affective, and 43 patients with Tourette`s syndrome, as well as 25 healthy controls) were investigated by single-strand conformation analysis. Overlapping PCR (polymerase chain reaction) fragments covered the whole coding sequence as well as the 5{prime} untranslated region of the 5-HT{sub 1A} gene. The region upstream to the coding sequence we investigated contains a …
