Status: draft. Extension maintained by: Health Level Seven International (Clinical Genomics)
The level of occurrence of a single DNA Sequence Variant within a set of chromosomes. Heterozygous indicates the DNA sequence variant is only present in one of the two genes contained in homologous chromosomes. Homozygous indicates the DNA Sequence Variant is present in both genes contained in homologous chromosomes. Hemizygous indicates the DNA Sequence Variant 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 Variant is present in some but not all of the copies of mitochondrial DNA. Homoplasmic indicates that the DNA Sequence Variant is present in all of the copies of mitochondrial DNA. LOINC Code: (53034-5).
