Figure 1

Human (Homo sapiens) TRG locus representation (A) and chromosomal localization (B), reproduced with permission from IMGT® (http://www.imgt.org). In (A), colors are according to IMGT color menu for genes (https://www.imgt.org/IMGTScientificChart/RepresentationRules/colormenu.php#LOCUS). The boxes representing the genes are not to scale. Exons are not shown. A double arrow indicates insertion/deletion polymorphisms. The Amphiphysin (AMPH) (IMGT 5′ borne) was identified 16 kb upstream of TRGV1 (ORF), the most 5′ gene in the locus, and the Related to steroidogenic acute regulatory protein D3-N-terminal like (STARD3NL) (3′ IMGT borne) was identified 9.4 kb downstream of TRGC2 (F), the most 3′ gene in the locus. In (B), a vertical red line indicates the localization of the TRG locus at 7p14. A blue arrow indicates the orientation 5′ → 3′ of the locus, and the gene group order in the locus. The blue arrow is proportional to the size of the locus, indicated in kilobases (kb). The total number of genes in the locus is shown in parentheses.
