case_images: Figure 2). Ferritin levels and transferrin saturation were increased in the presence of a normal HFE genotype. Case BIII.1 had mild microcytic anaemia, reticulocytosis, and increased ferritin levels; 17% of stomatocytes were detected at blood smear examination (Table 1 and Figure 2); the molecular testing for HBB gene revealed the presence of the splicing mutation c.93-21G>A at heterozygote level, confirming the beta-thalassemia trait.
case_images: Results of LoRRca Osmoscan analysis in the affected patients compared to a normal control performed by Laser-Assisted Optical Rotation Cell Analyzer (LoRRca MaxSis, Mechatronics, Hoorn, The Netherlands). The osmotic gradient curves reflect RBC deformability as a continuous function of suspending medium osmolality. The following parameters were evaluated: EImax (maximal deformability, reflecting mean cellular surface area), Omin (osmolality at which deformability reaches its minimum, reflecting mean cellular surface-to-volume ratio), and Ohyper (the osmolality in the hypertonic region corresponding to 50% of the EImax, reflecting mean cellular hydration status).
