β¦ Synopsis
The presence of a susceptibility locus for bipolar disorder on chromosome 5p near the dopamine transporter gene has been suggested. We examined 52 bipolar families for linkage to two markers in this region under both dominant and recessive models of inheritance. The purpose of the analyses was to determine the mode of inheritance of this purported bipolar locus. We also ran sensitivity analyses to confirm the reliability of the linkage results. Our results suggest that a bipolar locus inherited in an autosomal dominant fashion may be linked to this region in a subset of families.

method (P = 0.001), an affected sib pair method (ESPA, P = 0.0008), and the transmission disequilibrium test (P = 0.024). These results suggest the presence of a susceptibility locus for bipolar disorder near the DAT locus on chromosome 5.
Our aim was to analyze the GAW10 bipolar data on chromosome 18, using three well-known affected-sib-pair methods. Analyses were carried out on both individual and combined data sets. In these analyses we defined the affected phenotype to include only individuals with diagnosis of bipolar I. We obser
## Abstract The objective of this paper is to study the association between chromosomal fragile sites and type I bipolar disorder. This caseβcontrol study compares bipolar patients with normal controls. Ten cases of type I bipolar disorder diagnosed according to DSMβIIIβR criteria and the Composite
