This SNP influences skin pigmentation. The allele p.A111T, rs1426654(A), indicates light-skinned european ancestry. [PMID 16847698, PMID 16357253]
It appears as if this SNP is a relatively new one in human evolution; one estimate [PMID 17182896] is that the rs1426654(A) allele, in other words, light skin pigmentation, spread through the European population around 6,000 - 12,000 years ago. Prior to that, "European ancestors" were most likely relatively brown-skinned.
