Copied review below from Arianna Tucci (UCL) on Cytopenias and congenital anaemias (159) panel for HBG1 gene (also relevant to HBG2):

"delta beta thalassemia can result from deletions within or encompassing the beta-globin gene cluster (see HBB, 141900) on chromosome 11p15, including deletions that also encompass the delta-globin gene (142000), or from point mutations in the promoter regions of either the HBG1 (142200) or the HBG2 (142250) gene"

Copied review below regarding MOI from Arianna Tucci (UCL) on Cytopenias and congenital anaemias (159) panel:

"There are two alpha globin genes (HBA1 and HBA2), which are encoded in tandem on chromosome 16. Different Mutations in HBA1/HBA2 are associated with different α-thalassemias and different mode of inheritance: 1) α-thalassemia silent carrier: deletion/mutation that leads to loss of 1 α-globin gene (either HBA1 or HBA2) 2) α-thalassemia trait: deletion/mutations that leads to the loss of 2 α-globin genes either in cis (--/αα) or in trans (-α/-α); 3) Hemoglobin H disease is caused by contiguous gene deletion of HBA1 and HBA2 genes on one chromosome, and a defect (deletional / inactivating small indel /single nucleotide variant), in either HBA1 or HBA2 on the other chromosome; 4) 'homozygous alpha-thalassemia' (fatal hydrops fetalis): usually caused by deletions on both chromosomes, leading no/little production of alpha globin and death in utero. The phenotypes relevant to this panel are the α-thalassemia trait and the Hemoglobin H disease. Mostly caused by deletions but rare cases of small indels or point mutations leading to decreased production of the alpha globin chains have been described (16798638, 15481890, 15182057 for example)"
