A possible susceptibility locus for bipolar affective disorder in chromosomal region 10q25–q26
In an attempt to identify susceptibility loci for bipolar affective disorder, we are currently conducting a systematic genome screen with highly polymorphic microsatellite markers at an average marker spacing ...

Association study of the low-activity allele of catechol-O-methyltransferase and alcoholism using a family-based approach
Catechol-O-methyltransferase (COMT) is a major component of the metabolic pathways of neurotransmitters such as dopamine, adrenaline, and noradrenaline. The activity of COMT is known to vary within the populat...

Serotonin transporter gene and schizophrenia: evidence for association/linkage disequilibrium in families with affected siblings
The serotonergic (5-HT) system has been implicated in the etiopathogenesis of psychoses. Since the 5-HT transporter plays an important role in regulation of 5-HT transmission, its gene can be considered as a c...

DRD4 exon III VNTR polymorphism—susceptibility factor for heroin dependence? Results of a case-control and a family-based association approach
Dopaminergic abnormalities are implicated in the pathogenesis of substance abuse.1 Recently, two reports have been published suggesting an association between opioid dependence and presence of long alleles of the...

Association between hSKCa3 and schizophrenia not confirmed by transmission disequilibrium test in 193 offspring/parents trios
A possible association between the small conductance calcium-regulated potassium channel gene, hSKCa3, and schizophrenia has recently been described by Chandy et al1 using a case-control design with patients with...

Evaluation of linkage of bipolar affective disorder to chromosome 18 in a sample of 57 German families
Previously reported linkage of bipolar affective disorder to DNA markers on chromosome 18 was reexamined in a large sample of German bipolar families. Twenty-three short tandem repeat markers were investigated...

Linkage analysis of putative schizophrenia gene candidate regions on chromosomes 3p, 5q, 6p, 8p, 20p and 22q in a population-based sampled Finnish family set
During the past decade numerous studies have been published describing chromosomal regions potentially linked with schizophrenia. Unfortunately, none of these studies has been able to conclusively identify any...

Familienangehörige Schizophrener als Risikopersonen: Familiengenetik und neuere molekulargenetische Ansätze
Als Risikofaktoren für eine schizophrene Erkrankung gelten seit langem die familiäre Häufung und die teilweise genetische Determination, der jedoch kein bekannter monogener Erbgang zugrunde liegt. Statt dessen...

Evidence suggestive of a locus on chromosome 5q31 contributing to susceptibility for schizophrenia in German and Israeli families by multipoint affected sib-pair linkage analysis
Suggestive evidence for a potential susceptibility locus for schizophrenia at 5q31 was obtained in two family samples. Sample I consisted of 14 families with schizophrenia and revealed for the marker IL9 a lod...

Vulnerabilität für Schizophrenie: Entwicklung einer Modellvorstellung anhand von Familienstudien
Vulnerabilitätsmodelle für schizophrene und affektive Störungen gehen davon aus, daß sowohl klinische Störungen als auch subklinische Varianten und Normabweichungen durch dieselben disponierenden Faktoren evoz...

Gegenwärtiger Stand der Kopplungsuntersuchungen bei Schizophrenie
Für schizophrene Erkrankungen besteht ein deutlich erhöhtes genetisches Risiko, belegt durch Familien-, Zwillings- und Adoptionsstudien [1]. Die Konkordanzrate bei eineiigen Zwillingen beträgt etwa 50%, ein im...

The impact of gender and age at onset on the familial aggregation of schizophrenia
Some recent family studies have shown that the familial risk for schizophrenia is higher in female than in male schizophrenics. It is debated whether the risks for the other disorders, such as schizotypal pers...
