"+" 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.

IMGT notes:
  1. (1) In EMBL, a new accession number K02545 was created, the original accession number X00936 becoming secondary accession number of K02545.
  2. (2) The original L36092 sequence (684973 bp) has been split in EMBL into three sequences of 267156 bp (U66059), 215422 bp (U66060) and 232650 bp (U66061), L36092 has become secondary accession number of U66059, U66060 and U66061. In IMGT, the original sequence L36092 which is fully annotated has also been kept as primary accession number, in addition to U66059, U66060 and U66061.
