[[rs4911414]] is a SNP  near the [[ASIP]] (agouti signaling protein) gene on chromosome 20. 

This SNP is one of a tightly-linked pair that increases the likelihood of an individual being prone to [[sun sensitivity]], in other words, freckles and sunburn, based on a study of 6,000+ Caucasians (5,000+ Icelanders + 1,000+ Dutch). The odds ratios, presumably on a dominant basis, and at least in the largest population (Icelanders) for "freckles and burns vs. no freckles and tans" for the haplotype pair [[rs1015362]](G) - [[rs4911414]](T) is 3.91 (CI: 2.54-6.03) for males and 2.42 (CI: 1.52-3.86) for females, with an overall p=0.051.{{PMID|18488028}}

Based on a study by the same authors of 4,000+ [[skin cancer]] patients, this haplotype was seen to confer significant increased risk for cutaneous [[malignant melanoma]] (odds ratio 1.45, p = 1.2 x 10<sup>-9</sup>) as well as basal cell carcinoma (odds ratio 1.33, p = 1.2 x 10<sup>-6</sup>).{{PMID|18488027}}
