The human TRA/TRD locus is located on chromosome 14, on the long arm at band 14q11.2, the TRD locus is embedded in the TRA locus, between the TRAV and TRAJ genes.
Note that the TRDV3 gene localized in 3' of the TRDC gene is in inverted orientation of transcription.
In IMGT/GeneSearch, IMGT/GeneView and IMGT/LocusView:
The TRA/TRD locus localization (start and end: 127701-1058955 bp) and the gene positions are those in the clone contig which starts at the beginning of AE000658 and ends at the extremity of AE000662.
Clones (in blue) are those used for the complete sequencing of the human TRA/TRD locus.
