}}In a study of more than 500 Japanese patients with high [[myopia]], the [[rs2839471]](T) allele was associated with higher risk. The odds ratio is 1.68 (p=0.00027). {{PMID|18535602}}

Despite two previous GWAS studies associating this SNP with high myopia in Japanese populations, no association was seen in a Chinese population studied.{{PMID|22194655|OA=1
