Reference	Tested Markers	Statistical Values/Author Comments	Result Category	Comment on Study
Hu, X.,2010	Haplotype: rs10123629 - rs165596(), rs10123629 - rs178069(), rs10124883 - rs165596(), rs10124883 - rs178069()	Our results indicate that interactions between neurological pathway-related genes ASTN2 and SNAP29 or ASTN2 and PIK4CA, or other genes in linkage disequilibrium with any genes in these pairs, were risk factors of BPD, in both Caucasian and Chinese Han populations.	Positive	Comment on Study
Fallin, M. D.,2005		4 SNP typed, Median D'=1, Median r<sup>2</sup> =0.98, 1 LD blocks, 0.98 block coverage, all SNP or haplotype P-value > 0.05 in BP and SZ/SZA... This gene is not suggestive to BP.	Negative	Comment on Study

Gene relationship with SZ

Reference	Description	Result Category
16380905	This gene is not suggestive to SZ/SZA.	Negative
11317222	These data suggest that a mutation in the SNAP29 gene promoter region, or a mutation in linkage disequilibrium with the promoter SNP, may be involved in the pathogenesis of chromosome 22-linked SZ.	Positive
