For example, in the HL7 messages specified according to the HL7 V2 Clinical Genomics Fully LOINC-Qualified Genetic Variation Model, dbSNP entries can be used to as the observation values for DNA sequence variation identifiers. For example, OBX|1|CWE|48004-6^DNA Sequence Variation Identifier^LN||rs55538123^^dbSNP&#xD;&#xA;&#xD;&#xA;Versioning is identified by the build id. A new build is released approximately every six months or every year.
