Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | N/A |
|---|---|---|---|
| Common Name: | CD 90‐93 (-8bp): (‐AGCTTCGG) | HGVS Name: | HBA2:c.272_279delAGCTTCGG |
| Hb Name: | N/A | Protein Info: | N/A |
Context nucleotide sequence:

Also known as:
Comments: Reported in three members of a Chinese family. Initially found together with the --SEA deletion in a 2-year-old boy presenting with Hb H disease (Hb 87 g/L, MCV 61.1 fL, MCH 16.4 pg, Hb H 14.3%, Hb Bart's 2.4%). The father was homozygous for this deletion. The mother did not carry this deletion but her fetus, a second baby, had compound heterozygous mutations as the proband. Detected by CE and confirmed by gap-PCR and sequencing analysis.
