"+" 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.

In the "Clone names" column of "IMGT/LIGM-DB reference sequences" are shown the names of the lambda phages (for genomic sequences) or of the clones (for cDNA), and between parentheses cell lines, from which are derived the reference sequences.

IMGT notes:
  1. (1) TRGC1*01 and TRGC1*02 alleles were previously designated as gamma1b (D19 gamma1) and gamma1a (Raji gamma1), respectively [15].
  2. (2) Partial C-GENE: partial EX1 in 3'.
  3. (3) Partial C-REGION: partial EX1 in 5'.
  4. (4) The TRGC2 gene contains four or five exons due to the duplication (EX2T-EX2 or EX2R-EX2) or triplication (EX2T-EX2R-EX2) of exon 2 [5]. (2x) or (3x) indicates the duplication or triplication of the TRGC2 exon 2; respectively [14].
  5. (5) TRGC2*01(2x) and TRGC2*02(2x) alleles were previously designated as gamma2b (D7 gamma2) and gamma2a (D11 gamma2), respectively [15].
  6. (6) Productive, truncated chain at its C-terminal end following introduction of a STOP-CODON at position 7 of EX3 to obtain a soluble form.
