URL for this extension:

http://hl7.org/fhir/StructureDefinition/geneticsAllelicState

Status: draft. Extension maintained by: Health Level Seven International (Clinical Genomics)

The level of occurrence of a single DNA Sequence Variation within a set of chromosomes. Heterozygous indicates the DNA Sequence Variation is only present in one of the two genes contained in homologous chromosomes. Homozygous indicates the DNA Sequence Variation is present in both genes contained in homologous chromosomes. Hemizygous indicates the DNA Sequence Variation exists in the only single copy of a gene in a non- homologous chromosome (the male X and Y chromosome are non-homologous). Hemiplasmic indicates that the DNA Sequence Variation is present in some but not all of the copies of mitochondrial DNA. Homoplasmic indicates that the DNA Sequence Variation is present in all of the copies of mitochondrial DNA. Here is the loinc answer List for Allelic state:1. Heteroplasmic (LA6703-8); 2. Homoplasmic (LA6704-6); 3. Homozygous (LA6705-3); 4. Heterozygous (LA6706-1); 5. Hemizygous (LA6707-9).
