Abstract
Sickle cell disease (SCD) is an inherited autosomal recessive hemoglobin disorder caused by the presence of hemoglobin S, a mutant abnormal hemoglobin caused by a nucleotide change in codon 6 of the β-globin chain gene. SCD involves a chronic inflammatory state, exacerbated during vaso-occlusive crises, which leads to end-organ damage that occurs throughout the lifespan. SCD is associated with premature mortality in the first years of life. The process of sickling provokes asplenia in the first years of life with an increased risk of infection by encapsulated germs. These complications can be life-threatening and require early diagnosis and management. The most important interventions recommend an early diagnosis of SCD to ensure that affected newborns receive immediate care to reduce mortality and morbidity. The newborn screening program in the region of Murcia for SCD began in March 2016. We aimed to determine the incidence of sickle cell anemia and other structural hemoglobinopathies in the neonatal population of the region of Murcia, an area of high migratory stress, and to systematically assess the benefit of newborn screening for SCD, leading to earlier treatment, as well as to offer genetic counseling to all carriers. The prevalence of SCD in our region is similar to others in Spain, except for Catalonia and Madrid. The newborns with confirmed diagnoses of SCD received early attention, and all the carriers received genetic counseling.

Abstract
Hereditary pyropoikilocytosis (HPP) is characterised by severe hemolytic anemia due to membrane instability. We report the case of a 13-day-old boy with neonatal jaundice and severe hemolytic anemia. A peripheral smear examination showed severe anisopoikylocytosis. DNA sequencing revealed compound double heterozygous for mutant α-spectrin SPTA1 (Arg28His) and homozygous αLELY polymorphism (low expression α-spectrin allele), compatible with diagnosis of HPP.The patient required a blood transfusion initially, but spontaneously improved after two years. Our case illustrates that, despite the presence of the allele αLELY in homozygous, the clinical phenotype is similar to cases with a mutation in SPTA1 associated with αLELY in trans.
