A combined linkage analysis was performed on chromosome 18 data and produced modest evidence in three of four data sets for linkage of a susceptibility locus for bipolar disorder to markers on chromosome 18p. All data sets showed a preponderance of females among affected individuals. When this was t

β¦ Synopsis
Epidemiological studies have consistently found women to be at greater risk than men for affective disorders. This sex effect may help clarify genetic transmission and heterogeneity. Data from eight family studies of unipolar and eight family studies of bipolar probands were used to calculate family resemblance sex ratios. These observed sex ratios were then compared to sex ratios predicted by X-linked and nonfamilial effects models. Maximum likelihood estimation of competing models revealed that X linkage was not a good fit to the unipolar data. The bipolar studies were not consistent with either the X-linked or the nonfamilial effects model.

Genetic factors may be associated with disease subtype as well as susceptibility. We have therefore typed polymorphisms at the serotonin transporter, dopamine receptor, tryptophan hydroxylase, tyrosine hydoxylase, and monoamine oxidase A (MAOA) loci in 139 unipolar and 131 bipolar patients and inves

In a sample of 130 families ascertained through a bipolar proband without regard to psychiatric family history we analysed the frequency of maternal (MAT) and paternal (PAT) transmissions, the mo
