"+" or "-" indicates if the gene sequences have been found (+) or not been found (-) rearranged (R), transcribed (T) and/or translated into protein (Pr). Arbitrarily that information is shown on the first line of each gene when the data have been confirmed by several studies.

Functionality is shown between parentheses, (F) and (P), when the accession number refers to rearranged genomic DNA or cDNA and the corresponding germline gene has not yet been isolated.
Functionality is shown between brackets, [F] and [P], when the accession number refers to genomic DNA, but not known as being germline or rearranged.

The Sandbar shark (Carcharhinus plumbeus) IGHV genes and allele have a temporary designation based on the IMGT gene name nomenclature rules for the unmapped genes, the incomplete loci, or the cDNAs in the absence of germline genes.
Sandbar shark (Carcharhinus plumbeus) genes are designated by a number for the subgroup followed by the letter S and a number.
