title: Molecular linkage studies of bipolar disorders.
abstract: OBJECTIVE
  To review the reports of linkage findings for bipolar disorder.
  
  
  METHODS
  Literature review of published linkage findings in bipolar disorder.
  
  
  RESULTS
  There are several regions of the human genome that have been implicated repeatedly by independent investigators. These include 4p16, 12q24, 18q22, 18p11, 21q21 and 22q11. Two of these regions (18p11 and 22q11) are also implicated in genome scans of schizophrenia, suggesting that these two distinct nosological categories may share some genetic susceptibility. This hypothesis can only be tested when the underlying genes are identified.
