Concluding, the assays developed can be successfully applied for accurate, time and cost efficient simultaneous genotyping of SNPs associated with HbF levels in the BCL11A gene and in the HBS1L-MYB intergenic region in HPFH, β-thalassaemia, SCD or other hemoglobinopathy populations. The gene discussed is HBS1L; the disease is Schnyder corneal dystrophy.
