Common Name: 27.2 kb deletion (--27.2) HGVS Name: NC_00016.10:g.154539_181778delinsTAACA
Hb Name: N/A Protein Info: N/A

Also known as:

Comments: A 27.2-kb deletion and a 5-bp insertion (TAACA) in the α-globin gene cluster identified by MLPA. Breakpoints were predicted by targeted NGS and characterized by Sanger sequencing. The deletion starts downstream of HBZ between chr16:204470-204620 (upstream) and ends downstream of HBQ1 between chr16:231770-231920 (downstream) (GRCh37/hg19). The deletion covers the HBZP1, HBM, HBAP1, HBA1, HBA2, and HBQ1 genes.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
