Shi, J., 2007	SNP: rs2302762, rs2302765, rs3853818, rs4151120, rs9217 Haplotype: rs4151120 - rs3853818 - rs2302765 - rs2302762 - rs9217(T-T-T-T-T)	rs2302762 showed nominally significant transmission bias; haploview analyses showed nominally significant transmission bias of rs4151120-rs3853818-rs2302765-rs2302762-rs9217; no evidence of interaction among these 19 cholinergic genes by FITF analysis and FDR correction was found	Positive	Comment on Study
