Notes

From SNPedia

You have a rare genotype in a gene linked to colorblindness, however self reports by others with this genotype do not find any evidence of altered color perception. Consider taking some of these *http://www.color-blindness.com/2007/10/07/5-online-color-blindness-tests/ Three individuals with this genotype have emailed to confirm that they are not colorblind. However, one woman reports being red-green colorblind, as diagnosed by a physician. It is however possible her color blindness is unrelated to this SNP.
