Also known as:

Comments: Found in a heterozygous state in a 36-year-old Moroccan woman with normal laboratory findings and clinical image. Normochromic, normocytosis with Hb A2+Hb A2-X 2.0 % of total Hb. HbA2-Pontedera is detected by capillary electrophoresis, producing a slight shouldering of Hb A2 in a more anodic position on the Capi 3 Hemoglobin kit.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
