Popis: The report of a putative schizophrenia susceptibility gene linked to markers in the chromosome 5q11-q13 region and subsequent failures of replication have provoked considerable controversy. We here report six Welsh families multiply affected with schizophrenia in which there is no evidence for linkage between a dominant-like schizophrenia gene and 5q11-q13 markers. It is argued that our new results together with a combined reanalysis of previous studies suggest that a schizophrenia susceptibility gene can be excluded from the 5q11-q13 region. The apparent disparities between published results are most likely to reflect a chance finding in the one positive study and probably should not be interpreted as resulting from true linkage heterogeneity.
