Evaluation of the co-inheritance of the minor alleles A (rs766432) and T (rs6732518) in SCD individuals revealed that it was significantly linked to increased RBC count (p = 0.0126), Ht (p = 0.0032), and Hb (p = 0.0057) concentrations (Figure 4A,B,E). The gene discussed is GSTM1; the disease is Schnyder corneal dystrophy.
