“…With the increased sophistication of molecular studies and statistical power provided by the formation of large international collaborative efforts [Tsuang et al, ], evidence for candidate genes were identified at several chromosomes in linkage studies (although replication was not consistent), including 6p24‐22 [Antonarakis et al, ; Schwab et al, ; Straub et al, ; Wang et al, ; Moises et al, ; Wildenauer et al, ; Arolt et al, ; Maziade et al, ], 8p21‐22 [Pulver et al, ; Wildenauer et al, ], 10p11‐22 [Faraone et al, ; Schwab et al, ; Straub et al, ], 13q32 [Blouin et al, ], 15q13‐14 [Freedman et al, ; Kaufmann et al, ], and 22q12‐13 [Coon et al, ; Polymeropoulos et al, ; Pulver et al, ; Lasseter et al, ; Vallada et al, ; Moises et al, ; Gill et al, ; Ng et al, ].…”
