title: Failure to find a chromosome 18 pericentric linkage in families with schizophrenia.
abstract: A recent report of a possible linkage of bipolar affective disorder to a pericentric region of chromosome 18 initiated the present investigation to search for a similar linkage in 32 families with schizophrenia. The results of a study using 5 markers mapped to this region show negative lod scores and only weak evidence for any linkage by nonparametric analyses. If the previously reported finding is a true positive linkage for bipolar disorder, then either it is unlikely to be related to the genetics of schizophrenia, or the proportion of families linked to this region is small.
