Although a genetic susceptibility for schizophrenia has been long esta
blished and even noted by Kraepelin in 1907, the mechanisms for its in
heritance remains unknown. No candidates have proven to be correct and
while many weakly positive chromosomal linkages have been reported, n
one have yet been consistently replicated. The following review examin
es the present status of these findings. The conclusion is that the fi
eld must move on to finding a consistently replicable mutation segrega
ting with schizophrenia in families, before any of the present linkage
results can be resolved. (C) 1997 Elsevier Science B.V.
