Here you are: IMGT Web resources > IMGT Repertoire (IG and TR) > 1. Locus and genes

"+" or "-" indicates if the gene sequences have been found (+) or not been found (-) 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.

(s): transcript of a secreted chain.

IMGT notes:
  1. (1) Gene supposed to be functional: DELETION of nucleotide G in the L-REGION in EMBL flat file is probably due to a sequencing or typing error.
  2. (2) In the IGHA gene, the hinge and CH2 are joined in a single exon.
