Two-Parameter Characterization of Chromosome-Scale Recombination Rate (2009)

Li, Wentian, Freudenberg, Jan

The genome-wide recombination rate ($RR$) of a species is often described by one parameter, the ratio between total genetic map length ($G$) and physical map length ($P$), measured in centiMorgans...

Partial correlation analysis indicates causal relationships between GC-content, exon density and recombination rate in the human genome (2009)

Freudenberg, Jan, Wang, Mingyi, Yang, Yaning, Li, Wentian

Abstract Background Several features are known to correlate with the GC-content in the human genome, including recombination rate, gene density and distance to telomere. However, by testing for...

Brain-specific tryptophan hydroxylase 2 (TPH2): a functional Pro206Ser substitution and variation in the 5'-region are associated with bipolar affective disorder (2008)

Cichon, Sven, Winge, Ingeborg, Mattheisen, Manuel, Georgi, Alexander, Karpushova, Anna, Freudenberg, Jan, ...

The neurotransmitter serotonin [5-hydroxytryptamine (5-HT)] controls a broad range of biological functions that are disturbed in affective disorder. In the brain, 5-HT production is controlled by...

Huntingtin-associated protein-1 is a modifier of the age-at-onset of Huntington's disease (2008)

Metzger, Silke, Rong, Juan, Nguyen, Huu-Phuc, Cape, Austin, Tomiuk, Juergen, Soehn, Anne S., ...

A polyglutamine repeat expansion of more than 36 units in a protein called huntingtin (htt) is the only known cause of Huntington's disease (HD). The expanded repeat length is inversely correlated...

Human recombination rates are increased around accelerated conserved regions--evidence for continued selection? (2007)

Freudenberg, Jan, Fu, Ying-Hui, Ptácek, Louis J.

Motivation: We hypothesized that recombination rates might be increased at genetic loci that are subject to more intense selection. Here, we test this hypothesis by using a recently published set of...

Cannabinoid receptor type 2 gene is associated with human osteoporosis (2005)

Karsak, Meliha, Cohen-Solal, Martine, Freudenberg, Jan, Ostertag, Agnes, Morieux, Caroline, Kornak, Uwe, ...

Osteoporosis is one of the most common degenerative diseases. It is characterized by reduced bone mineral density (BMD) with an increased risk for bone fractures. There is a substantial genetic...

Single Nucleotide Variation Analysis in 65 Candidate Genes for CNS Disorders in a Representative Sample of the European Population (2003)

Freudenberg-Hua, Yun, Freudenberg, Jan, Kluck, Nadine, Cichon, Sven, Propping, Peter, Nöthen, Markus M.

The detailed investigation of variation in functionally important regions of the human genome is expected to promote understanding of genetically complex diseases. We resequenced 65 candidate genes...

The DTNBP1 (Dysbindin) Gene Contributes to Schizophrenia, Depending on Family History of the Disease

Van Den Bogaert, Ann, Schumacher, Johannes, Schulze, Thomas G., Otte, Andreas C., Ohlraun, Stephanie, Kovalenko, Svetlana, ...

We have investigated the gene for dystrobrevin-binding protein 1 (DTNBP1), or dysbindin, which has been strongly suggested as a positional candidate gene for schizophrenia, in three samples of...

Genetic Variation in the Human Androgen Receptor Gene Is the Major Determinant of Common Early-Onset Androgenetic Alopecia

Hillmer, Axel M., Hanneken, Sandra, Ritzmann, Sibylle, Becker, Tim, Freudenberg, Jan, Brockschmidt, Felix F., ...

Androgenetic alopecia (AGA), or male-pattern baldness, is the most common form of hair loss. Its pathogenesis is androgen dependent, and genetic predisposition is the major requirement for the...
