The GenomicSourceClass template represents the genomic class of the specimen being analyzed: germline for inherited genome, somatic for cancer genome (e.g. DNA from tumor cells), and prenatal for fetal genome. These options are coded in LOINC and may be bound to the value attribute of this template.

GTR GenomicSourceClass (self) SHALL satisfy: If self.code.code=48002-0 (LOINC code for Genomic source class), then self.value.code SHALL be drawn from the LOINC answer list 48002-0.
It is important to explicitly associate the specimen information to the clinical genomic statement (or a reference the specimen structured data in a Specimen section if specified), because the specimen is not part of the header and even if specified in a Specimen section, it doesn't apply necessarily to other parts of the GTR body by the CDA context conduction rules.
