Gene Gene information from NCBI Gene database.
Entrez ID 3048
Gene name Hemoglobin subunit gamma 2
Gene symbol HBG2
Synonyms (NCBI Gene)
HBG-T1TNCY
Chromosome 11
Chromosome location 11p15.4
Summary 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 s
