Linkage study of schizophrenia with markers on chromosome 11 in two Japanese pedigrees.
We examined the linkage between schizophrenia and DNA markers on chromosome 11 in two Japanese pedigrees. Thirty individuals from the two pedigrees were genotyped at the eleven polymorphisms (eight loci) studied. Data were analyzed according to three models, representing a range of single gene models from near dominant to an intermediate model. For all markers, except those at the D11S35 locus, there is no evidence for the linkage. Positive LOD scores between 1 and 1.5 are obtained for some genetic models with the polymorphism at D11S35. Two point scores for the broad diagnostic model and for the intermediate parameter set peak at 1.49.
