Rs2129785

Based on 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. uses regression model over eight SNP's available on Illumina microarray with higher expected accuracy.
