Arajärvi, Ritva, Ukkola, Jonna, Haukka, Jari, Suvisaari, Jaana, Hintikka, Jukka, Partonen, Timo, ...

Abstract Background Schizophrenia aggregates in families and accurate diagnoses are essential for genetic studies of schizophrenia. In this study, we investigated whether siblings of patients with...

Haplotype Transmission Analysis Provides Evidence of Association for DISC1 to Schizophrenia and Suggests Sex-Dependent Effects (2003)

Hennah, William, Varilo, Teppo, Kestilä, Marjo, Paunio, Tiina, Arajärvi, Ritva, Haukka, Jari, ...

We have previously reported a linkage peak on 1q42 in a Finnish schizophrenia sample. In this study we genotyped 28 single nucleotide polymorphisms (SNPs) from 1q42 covering the three candidate genes...

Chromosome 1 loci in Finnish schizophrenia families (2001)

Ekelund, Jesper, Hovatta, Iiris, Parker, Alex, Paunio, Tiina, Varilo, Teppo, Martin, Rory, ...

We have earlier reported evidence for linkage to two regions on chromosome 1q32–q42 in schizophrenia families collected for two separate studies in Finland. Here we report the results of a fine...

Genome-wide scan for schizophrenia in the Finnish population: evidence for a locus on chromosome 7q22 (2000)

Ekelund, Jesper, Lichtermann, Dirk, Hovatta, Iiris, Ellonen, Pekka, Suvisaari, Jaana, Terwilliger, Joseph D., ...

We report the results of a four-stage genome-wide scan in a schizophrenia study sample consisting of 134 affected sib-pairs collected in Finland. In stage I we genotyped 370 markers from the Weber 6...

A Genomewide Screen for Schizophrenia Genes in an Isolated Finnish Subpopulation, Suggesting Multiple Susceptibility Loci

Hovatta, Iiris, Varilo, Teppo, Suvisaari, Jaana, Terwilliger, Joseph D., Ollikainen, Vesa, Arajärvi, Ritva, ...

Schizophrenia is a severe mental disorder affecting ∼1% of the world's population. Here, we report the results from a three-stage genomewide screen performed in a study sample from an internal...
