Fig. 2. Results of spICA in discovery and replication sets.
The identified (a) GMV IC 1, (b) GMV IC 2, and (c) SNP component. The association between GMV IC 1 and SNP component was (d) significant in adults (the discovery set) and (f) replicated in adolescents (the replication set). e The association between GMV IC 2 and SNP component was significant in adults. In subplots a–c, hot colors represent positive weights, and cold colors denote negative weights. In subplots d–f, black, red, green, and blue colors represent all subjects, controls, cases, and unaffected siblings (SIB).
