hemoglobin subunit alpha 2 (HBA2) - coding DNA reference sequence

(used for mutation description)

(last modified February 4, 2018)


This file was created to facilitate the description of sequence variants in the HBA2 gene based on a coding DNA reference sequence following the HGVS recommendations.

The sequence was taken from NG_000006.1, covering HBA2 transcript NM_000517.4.


Please note that introns are available by clicking on the exon numbers above the sequence.

 (downstream sequence)
Legend:
Nucleotide numbering (following the rules of the HGVS for a 'Coding DNA Reference Sequence') is indicated at the right of the sequence, counting the A of the ATG translation initiating Methionine as 1. Every 10th nucleotide is indicated by a "." above the sequence. The Hemoglobin subunit alpha 2 protein sequence is shown below the coding DNA sequence, with numbering indicated at the right starting with 1 for the translation initiating Methionine. Every 10th amino acid is shown in bold. The position of introns is indicated by a vertical line, splitting the two exons. The start of the first exon (transcription initiation site) is indicated by a '\', the end of the last exon (poly-A addition site) by a '/'. The exon number is indicated above the first nucleotide(s) of the exon. To aid the description of frame shift mutations, all stop codons in the +1 frame are shown in bold while all stop codons in the +2 frame are underlined.
