IthaID: 3442



Names and Sequences

Functionality: Globin gene causative mutation
Common Name: CD 51-58 (+24 bp) HGVS Name: HBA1:c.157_180dupTCTGCCCAGGTTAAGGGCCACGGC
Hb Name: Hb Choisy Protein Info: N/A

Context nucleotide sequence:
CCCGCACTTCGACCTGAGCCACGGC [-/TCTGCCCAGGTTAAGGGCCACGGC] AAGAAGGTGGCCGACGCGCTGACCA (Strand: +)

Comments: Insertion of eight amino acids (Ser-Ala-Gln-Val-Lys-Gly-His-Gly) due to a 24 bp duplication from nucleotide 157 to 180. The His(E7) residue appears to be in its normal position, while the eight additional residues are probably inserted at the beginning of helix E, increasing its size, but with mild effects on folding and heme contact.
