Comments: Reported in one case from Sabah in compound heterozygosity with -α4.2 [IthaID:301]. Presented with normal levels of Hb 11.4 g/dL and RBC 5.36 10^12/L and reduced levels of MCV 70.1 fL and MCH 21.3 pg. Capillary electrophoresis shown reduced level of HbA2 1.7% with an abnormal peak of 29.9 % (at zone E) and a small abnormal peak at Z1 (0.8%).

We follow the HGVS sequence variant nomenclature and IUPAC standards.
