Broadly there are three alternative sampling strategies for linkage studies of complex disorders such as schizophrenia. These are to select either affected sib pairs (and their parents) or small-to-medium-size pedigrees, or large pedigrees. The advantages and disadvantages of each are discussed. Our studies show that, even in the presence of heterogeneity,(More)
Using exact expected likelihoods, we have computed the average number of phase-unknown nuclear families needed to detect linkage and heterogeneity. We have examined the case of both dominant and recessive inheritance with reduced penetrance and phenocopies. Most of our calculations have been carried out under the assumption that 50% of families are linked(More)
We studied seven informative kindreds segregating for manic depressive illness (MDI), consistent with X-chromosome transmission of the trait (families do not show affective disease in both a father and a son), using markers mapped to the region of Xq27-Xq28. The lod scores were consistently below -2 in the region extending from about 10 cM centromeric from(More)
A cDNA encoding a G protein-coupled receptor that appears to mediate the behavioral effects of cannabinoids, the psychoactive ingredients of marijuana, has recently been cloned from rat cerebral cortex and expressed. We have now determined the genomic location of the human cannabinoid receptor gene (CNR) by a combination of genetic linkage mapping and(More)
