IGHD4/OR15-4a*01, IGHD4/OR15-4b*01: a Homo sapiens IGH D allele sequence, 19 nt, non-functional. The nucleotide sequence is below, with every recorded name and its source.

Coding sequence (nt)

Name history i: stable — no former names, re-cuts, or archival on record.

Allele names i

Every name below denotes this exact sequence (HUMAN-DUWUU5DRK). None is canonical; they are labels, and the UID is the key.

Multiple allele designations. This one sequence is recorded under 2 different allele designations: IGHD4/OR15-4a*01, IGHD4/OR15-4b*01. These are identical normalized nucleotide sequences with different attributed names.

Find similar (nt · aa · cross-species) i

Everything comparative about this sequence (the exact differences to other alleles, protein consequence, IMGT alignment, cross-species nearest) is shown per hit in the results of this query.

Restricted for D genes: only 19 nt alleles are compared, position by position. D genes are too short (8–148 nt, median 19 nt) for edit-distance scores to be interpreted reliably; the metric can open gaps that inflate identity, and at 19 nt the 0.75 identity floor is about four mismatches. A D allele is therefore compared only against D alleles of exactly the same length, scored position by position. Alleles of the same gene that differ in length are not ranked here; separating those requires a multiple-sequence alignment, not a pairwise score.

Ranks D alleles of the same length, by positional identity. Also available at /api/sequences/HUMAN-DUWUU5DRK/similar?min_identity=0.95&kind=nt.
