Coverage is partial. Citations arrive two ways: a source publishes them with its records, or AIRBabel mines a paper's full text and supplements. Neither is exhaustive; most of what is loaded today comes from curated sets that carry their own references. An empty result therefore means AIRBabel holds no citation linking that paper to an allele, not that the paper describes none. Treat a linked record as evidence within AIRBabel and an empty result as absence of recorded linkage.

% identity by species; each dot is one match (100 shown).

What do these match types mean?
exact
The query sequence and the stored sequence are identical after normalisation; same hash, so the same allele, whatever either is called.
substring
One sequence is fully contained in the other: your query is a fragment of this allele, or this allele is a fragment of your query. No mismatches.
similar
Neither exact nor contained: ranked by % identity (how it is computed). Read the Identity column with it.
name
Matched on a label, not on sequence. A name match says nothing about the sequence; the same name denotes different sequences in different species.
cached
Served from the precomputed neighbour cache. Same identity calculation, computed ahead of time.
protein_uid
Matched a protein UID: these V alleles differ in nucleotide sequence but translate to the same amino-acid sequence.
superseded
Not a match type but a record status: IMGT has since published this allele at a different extent. The tag links to the current record.
