rs4778241 is part of a haplotype spanning 166kB on chromosome 15, defined by 13 SNPs listed below, found in 97% of all Caucasians with blue eyes. In this haplotype, variations in rs1129038 and rs12913832 are relatively common in Caucasians though rare among other ethnic groups.[PMID 18172690]
The "h-1" haplotype found in homozygous state in 97% of individuals with blue eye color is composed as follows [PMID 18172690]:
rs12913832(G) (this appears to be the causative SNP)
rs7170852(A) (this snp seems flipped, or odd)
