This case-sensitive code system http://hl7.org/fhir/oligo-nucleotide-type defines the following codes:

CodeDisplayDefinitionCopy
antisense Antisense oligonucleotide An antisense oligonucleotide (ASO) that binds to a complementary mRNA sequence to inhibit gene expression. btn btn
sirna Small interfering RNA (siRNA) A short double-stranded RNA that triggers degradation of a target mRNA through the RNA interference pathway. btn btn
mirna MicroRNA (miRNA) A short non-coding RNA that regulates gene expression by base-pairing with target mRNAs. btn btn
aptamer Aptamer A short single-stranded oligonucleotide that binds a specific target through its three-dimensional structure. btn btn
decoy Decoy oligonucleotide An oligonucleotide that mimics a regulatory binding site to sequester a transcription factor or other binding protein. btn btn
ribozyme Ribozyme / DNAzyme A catalytic oligonucleotide capable of cleaving a target nucleic acid. btn btn
gene-fragment Gene fragment A fragment of a gene such as a promoter, enhancer, coding region or silencer. btn btn

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
