Hemoglobinopathies are hereditary autosomic recessive diseases. A total of 70 943 samples of whole blood collected by heel prick in filter paper (S&S 903) from throughout Costa Rica (October 2005-October 2006) were analyzed to detect variants of hemoglobin by the iso-electric focusing technique. Eight hundred ninety one cases presented some variant, for a frecuency of 1/79. Five cases are homozygous for hemoglobin S (sickle cell disease) and one shows the double heterozygous genotype SC. In this study the S and C variants of hemoglobin, although with some local differences, are widespread all over the country. Thus, the prevention of new cases is important through the testing of hemoglobin in the Costa Rican National Newborn Screening Program, together with a Interdisciplinary National Program of Education for the disease and carrier status (AS/AC) for patients, families and medicar personnel. This is the basis for proper genetic counseling, to improve treatment and to reduce morbi-mortality.

Dias-Logan syndrome, also known as intellectual developmental disorder with persistence of fetal hemoglobin (HbF), or -related intellectual developmental disorder, is an extremely rare neurogenetic disorder characterized by intellectual disability (ID), delayed psychomotor development, variable dysmorphic features, and asymptomatic persistence of fetal hemoglobin. The prevalence and incidence of this condition are currently unknown. We report an 8-year-old Han Chinese male patient with Dias-Logan syndrome who carries a heterozygous pathogenic variant, c.

Sickle cell disease (SCD) and thalassemia are the most common hereditary disorders encountered in Central India. Timely identification of these disorders is critical to reduction in severe clinical manifestations and for identifying disease burden. Present study reports spectrum of hemoglobinopathies among the referred anemia patients to single centre in central India.

Background: Storage of packed red blood cells (RBCs) for transfusion leads to biochemical and morphological changes, increasing hemolysis risk. Urate levels in blood bags at donation contribute to the molecular heterogeneity and hemolytic propensity of stored RBCs. However, studies to date have been underpowered to investigate at scale the contribution of donor demographics and genetics to the heterogeneity in urate levels across donations.

Sickle cell disease (SCD) is an inherited hematologic disease caused by sickle hemoglobin as the predominant RBC hemoglobin or by sickle hemoglobin in combination with other abnormal β-hemoglobin variants like HbC, HbD and others. Sickling of erythrocytes under deoxygenated conditions is the basis of inflammatory and thrombotic cascades which result in multiple serious complications, leading to early morbidity and mortality. While HLA-matched allogeneic bone marrow transplantation is potentially curative, it has considerable limitations due to potential severe toxicities.
