| Common Name: | αααα282 | HGVS Name: | NC_000016.10:g.44054_44055ins[NC_000016.10:g.10001_232200] |
We follow the
HGVS sequence variant nomenclature
and
IUPAC standards.
Comments: The duplication spans a region starting from the telomere (position 60001 bp) to a downstream breakpoint localized to position 282,199 bp (GRCh37.p13). The duplication segment is inserted between 94,054-94,055 bp (GRCh37.p13). According to the telomere starting site, the duplication spans a smaller region of 222 kb including entire α-globin locus. Heterozygosity for this duplication defect (6 instead of 4 α-globin genes) associated with normal haemoglobin levels. Co-inheritance with a β-globin gene defect associated with a β-thalassemia intermedia status.
