The human (Homo sapiens) TRG locus is located on chromosome 7 [1,2], at band 7p14 [3].
The orientation of the human TRG locus on the chromosome is reverse (REV).
The orientation of the locus has been determined by the analysis of
chromosome 7 inversions inv(7)(p14-q34), involving the TRG and TRB
loci in ataxia telangiectasia patients, and in leukemia.
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 between parentheses.
