Figure 4. rs7412 has an average heterozygosity of 18.3% based on the frequency data provided by seven submissions, and the cluster as a whole is validated because at least one of the underlying submissions has been experimentally validated. rs7412 is annotated as a variation feature on RefSeq contigs, mRNAs, and proteins. Pointers in the refSNP summary record direct the user to additional information on six additional Web sites, through linkout URLs. These Web sites may contain additional data that were used in the initial variation call, or it may be additional phenotype or molecular data that indicate the function of the variation.
