© CDISC 2014 PGx Specific Variables - Specimen 7 NameLabelNotes --REFID Reference IDSpecimen identifier. --PARENTSpecimen ParentWhen the specimen in question has been obtained from another specimen (e.g., via resectioning, aliquoting), --PARENT holds the ‑‑ REFID of the “parent specimen;” that is, the specimen from which the current specimen has been obtained. --SPCLVLSpecimen LevelAny specimen obtained directly from the subject has a specimen level of 1. Specimens obtained from a level 1 specimen have a specimen level of 2; from a level 2 specimen have a specimen level of 3; etc. A level 4 specimen, therefore, would be a specimen (4) obtained from a specimen (3) obtained from a specimen (2) obtained from a specimen (1) obtained from the subject. --DTCDate/Time CollectedDate/time of specimen collection. For specimens with a specimen level greater than 1, ‑‑ DTC refers specifically the date/time of collection for the originating specimen, i.e., the specimen obtained directly from the subject. A specimen is a sample of the subject which undergoes a test in place of the subject when the test cannot be performed on the subject directly, with the understanding that any results obtained thereby may be treated as pertaining to the subject. However, once the specimen has been separated from the subject, any changes in the subject’s state will not be reflected by the specimen. Therefore, when a test is performed on a specimen, the results cannot be guaranteed to pertain to the subject as they are at the time of the test, only to the subject as they were at the time of specimen collection.

© CDISC 2014 Variables – (Pathogens) 11 NameLabelNotes --MSPCES***Microorganism Species In findings domains, --SPCIES holds the species of the pathogen to which the subject is a host when the pathogen is the focus of the. In instances when both the subject and the pathogen are tested, records for the pathogen are distinguished and differentiated from records for the subject by the use of the --SPCIES variable. Not to be confused with DMSPCIES, which holds the species of the subject. --MSTRNMicroorganism Strain As --SPCIES. --STRAIN holds the strain of the pathogen to which the subject is a host when the pathogen is the focus of the test. *** SDTMIG omits --SPCIES because all subjects in most human clinical trials must be homo sapiens; the nature of the study obviates the need for this information to be included in SDTM datasets. The exception is Virology when a viral species must be identified.
© CDISC 2014 Variables – (Genetics/Genomics Test related) 12 NameLabelNotes --TESTTest Name For genetic variation, usually the level of granularity and/or molecular component of interest: Examples: Nucleotide, Amino Acid, Allele --REFSEQReference SequenceDepending on the type of test method, the reference sequencing is most likely to be either the rsID from dbSNP (for targeted tests) or a GenBank accession number (for non-targeted tests). --GENTYPType of Genetic Region of Interest The type the portion of the genome serving as a locus for the experiment/test. Examples: GENE, SECTOR, PROTEIN --GENRIGenetic Region of InterestThe portion of the genome serving as a locus for the experiment/test. Often the name of a gene. Examples: EGFR, KRAS, CYP2D6 --GENLIGenetic Location of Interest The numeric position within the sequence for the targeted read. Compare vs. --GENLOC. --GENLI and --GENTGT are variables that should be used only when the the test specifies a single genetic read to the exclusion of all other possibilities, and the result is a matter of occurrence, either as a percentage or as a boolean observation. --GENTGTGenetic TargetThe genetic read targeted by the probe at the position specified by --GENLI. --ALLELCAlleleHumans are diploid: they have two homologous copies of each chromosome. However, the two copies are not necessarily identical, since one chromosome is inherited from each parent. Therefore, in tests that compare chromosomes, or parts of chromosomes (alleles), the --ALLELE variable is used to denote results for one or the other of the two alleles (chromosomes).
© CDISC 2014 Variables – (Genetics/Genomics Result related) 13 NameLabelNotes --GENSRGenetic Sub-RegionThe sub-region within the genetic region of interest in which the observed varition at the position given in --GENLOC is located, if relevant. Because exon numbers can be variable and are not regulated, caution should be exercised when populating this variable. --GENLOCGenetic LocationOne of the three variables used to define a genetic read. --GENLOC holds the numeric position within the sequence for the observed result. --ORRESResult or Finding in Original Units One of the three variables used to define a genetic read. --ORRES holds the observed result at the position specified by --GENLOC. When --GENLI is populated, --ORRES follows the standard rules. --ORREFReference ResultOne of the three variables used to define a genetic read. --ORREF holds the expected result at the position specified by --GENLOC according to the reference sequence specified by --REFSEQ. --STRESCResult or Finding in Standard Format When --GENLOC is populated, --STRESC holds the observed variation, given in HGVS nomenclature. When --GENLI is populated and --ORRES=Y, --STRESC holds the observed variation as targeted, given in HGVS nomenclature. Otherwise, --STRESC is copied or derived from --ORRES. --RSNUMReference SNPReference identifier for previously identified instances of the variation, such as the rs# in dbSNP. --MUTYPMutation TypeThe type of mutation, usually either GERMLINE (inherited) or SOMATIC (arising only in parts of the individual, as in cancer). --ANMETHAnalysis Method Analysis method applied to obtain a summarized result. Analysis method describes the method of secondary processing applied to a complex observation result (e.g. an image or a genetic sequence).
