1 ). To prioritize associated SNPs for follow up analyses, we used a Bayesian strategy to derive the smallest set of variants that included the causal variant with ninety five% likelihood (95% credible set) ( 7 ). Five SNPs were included in this 95% credible set ( SI Appendix, Table S1 ). We then performed a replication affiliation analysis of those 5 SNPs in an unbiased cohort of 222,358 men (2,957 instances and 219,401 controls) from the UK Biobank ( SI Appendix, Desk S2 ). All 5 credible set SNPs had been considerably viagra 100mg related to erectile dysfunction in the replication analysis (P zero.01 required for multiple testing; all SNPs have been relaed P 10−thirteen) in the identical course as the GERA cohort results SI Appendix, Table S3 ). As evolutionary conservation is a strong marker of purposeful genomic sequences, we focused our observe-up analyses on one of many five SNPs, rs17185536, which was the only SNP positioned in an evolutionarily conserved region ( 8 ).
