[PMID 19204306] rs10494366, rs4657139 and rs16847548 were significantly associated with adjusted QT interval in whites. relative hazard of SCD associated with each C allele at rs16847548 was 1.31. rs12567209 was also independently associated with SCD in whites (relative hazard 0.57, 95% confidence interval 0.39 to 0.83, P=0.003). No significant associations observed in blacks.
