}}Based on {{PMID|21670732|OA=1
}} with 2823 samples a haplotype of A+A in [[rs2129785]]+[[rs11867581]] predicts short allele of [[5-HTTLPR]] with good accuracy. Haplotype G+G has not been generally observed, so phase can always be determined. The only possible haplotypes are thus A+A short 91% of the time, A+G long 96% of the time and G+A always long. {{PMID|22504458}} uses regression model over eight [[SNP]]'s available on [[Illumina]] [[microarray]] with higher expected accuracy.
