Monoamine related functional gene variants and relationships to monoamine metabolite concentrations in CSF of healthy volunteers (2004)

Jönsson, Erik G, Bah, Jessica, Melke, Jonas, Abou Jamra, Rami, Schumacher, Johannes, Westberg, Lars, ...

Abstract Background Concentrations of monoamine metabolites in human cerebrospinal fluid (CSF) have been used extensively as indirect estimates of monoamine turnover in the brain. CSF monoamine...

Can long-range microsatellite data be used to predict short-range linkage disequilibrium? (2002)

Schulze, Thomas G., Chen, Yu-Sheng, Akula, Nirmala, Hennessy, Kathleen, Badner, Judith A., McInnis, Melvin G., ...

The distribution of linkage disequilibrium (LD) across the genome is highly complex. Little is known about the relationship between long-range and short-range LD in a genomic region. We assessed...

A genome screen for genes predisposing to bipolar affective disorder detects a new susceptibility locus on 8q (2001)

Cichon, Sven, Schumacher, Johannes, Müller, Daniel J., Hürter, Martina, Windemuth, Christine, Strauch, Konstantin, ...
