IthaID: 3464
Names and Sequences
Functionality: | Globin gene causative mutation | Pathogenicity: | Pathogenic / Likely Pathogenic |
---|---|---|---|
Common Name: | CAP +3 A>T | HGVS Name: | HBB:c.-48A>T |
Hb Name: | N/A | Protein Info: | N/A |
Context nucleotide sequence:
AGGGCAGAGCCATCTATTGCTTAC [A>T] TTTGCTTCTGACACAACTGTGTT (Strand: -)
Also known as:
Comments: The nucleotide +3(A) from the CAP site is part of the initiator element (consensus sequence: Py-Py(C)-A+1-N-T/A-Py-Py) and an overlapping E-box (consensus sequence: CANNTG), possibly contributing to the efficient assembly of preinitiation complex on the β-globin gene. Co-inherited with 92+1G>A mutation in a case of β-thalassemia intermedia. Source: Romanian Biotechnological Letters, Vol. 16, No. 2, 2011
