Part Descriptions

LP94324-8   HBA2 gene
The HBA1 gene (hemoglobin, alpha 1) [HGNC Gene ID:4823] is located on chromosome 16p13.3. The human alpha globin gene cluster located on chromosome 16 spans about 30 kb and includes seven loci: 5'- zeta - pseudozeta - mu - pseudoalpha-1 - alpha-2 - alpha-1 - theta - 3'. The alpha-2 (HBA2) and alpha-1 (HBA1) coding sequences are identical. These genes differ slightly over the 5' untranslated regions and the introns, but they differ significantly over the 3' untranslated regions. Two alpha chains plus two beta chains constitute HbA, which in normal adult life comprises about 97% of the total hemoglobin; alpha chains combine with delta chains to constitute HbA-2, which with HbF (fetal hemoglobin) makes up the remaining 3% of adult hemoglobin. Alpha thalassemias result from deletions of each of the alpha genes as well as deletions of both HBA2 and HBA1; some nondeletion alpha thalassemias have also been reported.

Change Reason
Based on LOINC Committee review (June 2016), "targeted" was added to the Component to clarify that this test is looking for a specific set of mutations as described in the LOINC User Guide under the Molecular Genetics section.; Based on LOINC Committee review (June 2019), updated the Property from "Prid" to "Find" and Scale from "Nar" to "Doc" to align with the current LOINC model for naming collections of information reported in narrative and/or structured formats.
