Comments: Found in a healthy heterozygous patient presented with Hb 12.6 g/dL, MCV 83 fL, MCH 31.5 pg and RBC 4.8 10^12/L. Capillary electrophoresis shown that the HbX variant migrated in zone 13 with HbX level 13.1% and HbA2 2.5%. No separation of HbX and HbA found with HPLC analysis.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
