|---|---|---|---|
| Common Name: | IVS I-38 C>T | HGVS Name: | HBA1:c.95+38C>T |
| Hb Name: | N/A | Protein Info: | N/A |
Context nucleotide sequence:
CCCCTGCTCCGACCCGGGCTCCTCG [C>T] CCGCCCGGACCCACAGGCCACCCTC (Strand: +)
Also known as:
Comments: Detected together with CD 19 (-G) [ithaID=2465] in an Iranian subject with elevated Hb Bart's levels. The effect of this mutation on HBA1 gene expression is unclear as no regulatory sites seem to be involved. No mRNA analysis was performed to determine whether this mutation affects the α-gene expression or is merely a polymorphism.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
