Previous GeneCards Identifiers for HBG2 Gene
The gamma globin genes (HBG1 and HBG2) are normally expressed in the fetal liver, spleen and bone marrow. Two gamma chains together with two alpha chains constitute fetal hemoglobin (HbF) which is normally replaced by adult hemoglobin (HbA) at birth. In some beta-thalassemias and related conditions, gamma chain production continues into adulthood. The two types of gamma chains differ at residue 136 where glycine is found in the G-gamma product (HBG2) and alanine is found in the A-gamma product (HBG1). The former is predominant at birth. The order of the genes in the beta-globin cluster is: 5'- epsilon -- gamma-G -- gamma-A -- delta -- beta--3'. [provided by RefSeq, Jul 2008]
GeneCards Summary for HBG2 Gene
HBG2 (Hemoglobin Subunit Gamma 2) is a Protein Coding gene. Diseases associated with HBG2 include cyanosis, transient neonatal and fetal hemoglobin quantitative trait locus 1. Among its related pathways are Platelet activation, signaling and aggregation and Factors involved in megakaryocyte development and platelet production. GO annotations related to this gene include iron ion binding and oxygen binding. An important paralog of this gene is HBA2.
