Generated Narrative: CodeSystem topology

This case-sensitive code system http://hl7.org/fhir/uv/molecular-definition-data-types/CodeSystem/topology defines the following codes:

Code	Display	Definition
linear	Linear	Linear, contiguous (e.g., Sequence, Allele)
linear-discontiguous	Linear discontiguous	Linear, with gaps (e.g., Haplotype)
circular	Circular	Circular, contiguous (e.g., Sequence, Allele)
branched	Branched	Branched (e.g., carbohydrate modifications)
