In HL7 V2 they can be reported in one observation as a list separated by repeat delimiters OR as a series of separate OBX segments, one per mutation tested for. In FHIR, multiple coded entries can not be reported as a list in one observation value field. They must be reported as the values of separate observations.

DNA region of interest NumRange

• linkId: /81306-3/51959-5
• Answers:

This term is used to report the region(s) of interest for sequencing studies as one or more numeric ranges that identify the parts of the reference sequence that are sequenced. These can be recorded as one or more HL7 numeric ranges using repeat delimiters to seperate multiple such ranges. They can also be recorded singly, one per OBX, using OBX-4 to distinguish these repeats with the same Observation ID. However, such detailed specification of the sequencing region of interest is rare, in part because this information is often proprietary, and the region of interest is reported as a text description instead, e.g., "Sequenced all of the coding, and appropriate flanking regions," using [LOINC: 81293-3].

This term is used to report a narrative description of the range(s) of DNA sequences examined in this sequencing study. Genetic test reports only rarely include explicit numeric ranges (which would be reported using [LOINC: 51959-5]) beause they are often proprietary, and more often describe the regions examined in narrative. For example, "all coding regions and appropriate flanking regions." To report the region of interest (e.g., in terms of introns and exons) rather than the specific DNA sequences examined, [LOINC: 47999-8] may be used.

• Answers:

The fraction of all reads in a study sample at a given genomic locus that identify the allele (variant) in question. For homozygotes it will be close to 1.0; for heterozygotes it will be close to 0.5. It can be less than 0.5 in the case of mosaics or multiple chromosome, or mixtures of tumor cells and normal cells. This measure is an attribute of the variant and applies when the method is a Next Generation Sequencing (NGS) or similar. Such methods provide many reads from the sample for each locus. To report population allelic frequency, see [LOINC: 92821-8]. Allelic frequency is usually reported as a decimal fraction for both Sample Variant Allelic Frequency and Population Allelic Frequency, although it is occasionally reported as a percent. Special care/caution should be taken when reporting and converting to a decimal fraction.

That is if the sequence variation is an insertion, then Reference Nucleotide will be blank and Variable Nucleotide will contain the inserted nucleotides. In contrast, if the sequence variation is a deletion, then the Reference Nucleotide will contain the deleted nucliotieds, and the Variable Nucleotide will be blank.

• linkId: /81251-1/81250-3/81258-6
• Answers:

The fraction of all reads in a study sample at a given genomic locus that identify the allele (variant) in question. For homozygotes it will be close to 1.0; for heterozygotes it will be close to 0.5. It can be less than 0.5 in the case of mosaics or multiple chromosome, or mixtures of tumor cells and normal cells. This measure is an attribute of the variant and applies when the method is a Next Generation Sequencing (NGS) or similar. Such methods provide many reads from the sample for each locus. To report population allelic frequency, see [LOINC: 92821-8]. Allelic frequency is usually reported as a decimal fraction for both Sample Variant Allelic Frequency and Population Allelic Frequency, although it is occasionally reported as a percent. Special care/caution should be taken when reporting and converting to a decimal fraction.
