Based on the International Classification of Diseases, 11th Revision (ICD-11) considering classification of G6PD deficiency under haemolytic anaemias (code: 3A10.00) [33], the data demonstrated that malaria patients with G6PD deficiency prior to treatment, particularly the G6PD MahidolG487A mutation, displayed signs of haemolytic anaemia, including low haemoglobin, RBC count, haematocrit, and high reticulocyte count. This evidence concerns the gene G6PD and malaria.
