However, at present, it is impractical to screen the entire genome by association and therefore candidate genes must be selected. Detera-Wadleigh SD, Badner JA, Berrettini WH, Yoshikawa T, Goldin LR, Turner G A high-density genome scan detects evidence for a bipolar-disorder susceptibility locus on 13q32 and other potential loci on 1q32 and 18p11. It contains numerous small gaps and, although there is preliminary information on gene position and structure, there is little data on predicted function.

Furthermore, schizophrenia linkage studies from Finland generated confirmatory results near the 1q42. Our Wessex data may be enriched for non-firstborn individuals. Schizophrenia susceptibility associated with interstitial deletions of chromosome 22q11.

Chromosomal banding studies can quickly locate the gross morphological areas disrupted by chromosomal aberrations. A balanced chromosomal translocation partially co-segregating with psychotic illness in a family. Schizophrenia spectrum disorders: an autosomal-wide scan in multiplex pedigrees.

    Velo-cardio-facial and partial DiGeorge phenotype in a child with interstitial deletion at 10p13—implications for cytogenetics and molecular biology. A case report of a mother and daughter with chromosome 21p deletion and bipolar disorder adds some support to the suggestion that this locus might be on 21p. Chromosomal loci identified by aberrations that met the criteria mentioned above (several Independent Cases, IC; LinKage support, LK; Co-Segregation, CS; significant Co-Segregation, CS Table 1 - Chromosomal rearrangements or anomalies associate with psychiatric disorder.

    Bipolar affective disorder partially cosegregates with a balanced t(9;11)(p24;q23. Cary, NC, USA) for regression, logisitic regression means tests and statistics in frequency tables. Although slightly proximal to the region of highest linkage, the association between Prader–Willi syndrome at 15q11–13 and affective psychotic disorder and especially the recent striking finding of an apparent excess of uniparental disomy cases is noteworthy.

    In two families, genes have already been cloned that are directly disrupted by chromosomal translocations. Cytogenetic abnormalities on chromosome 18 associated with bipolar affective disorder or schizophrenia. Despite concerns outlined in 1 and 2, all our results from our regression show the intercept as not being significantly different from zero, which suggests the control population is appropriate. The presence of a chromosomal abnormality was considered significant if one or more of the following criteria was met: (a) there were reports of independent cases of a rare chromosomal abnormality associated with psychiatric illness; (b) there was colocalisation of the abnormality with a region of positive linkage, or; (c) familial cosegregation of the abnormality with psychiatric illness was demonstrated; when the co-segregation was shown to be statistically significant these were given greater weight.
