LOINC description : The unique identifier for the variant represented as a small nucleotide polymorphism
(SNP). The dbSNP ID is used routinely as the base identifier in pharmacogenomics as
well as arrCGH studies. For example, for the simple variant NM_014049.4(ACAD9):c.1249C
T (p.Arg417Cys), the dbSNP ID is 368949613. [http://www.ncbi.nlm.nih.gov/clinvar/variation/30880/];
