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]:

rs4778241(C)
rs1129038(A)
rs12593929(A)
rs12913832(G) (this appears to be the causative SNP)
rs7183877(C)
rs3935591(G)
rs7170852(A) (this snp seems flipped, or odd)
rs2238289(T)
rs3940272(C)
rs8028689(T)
rs2240203(A)
rs11631797(G)
rs916977(G)
