Human (Homo sapiens) TRG locus (on chromosome 7 at 7p14) gene repertoire per assembly:

Human (Homo sapiens) TRGV gene numbers per subgroup in IMGT annotated assemblies:

For each available species and locus, the evaluation of a locus gene repertoire is displayed in tables per gene type: V, D, J or C.
The first column on the left lists either IMGT subgroups for V genes, or IMGT sets or subgroups for D and J genes, or IMGT gene names for constant genes. Clicking on the link provides the lists of corresponding IMGT alleles per IMGT functionality.
Columns in «IMGT annotated assemblies» display for each IMGT annotated assembly the number of IMGT genes per functionality.
The two columns in «Number of genes» are shown only if there is more than one IMGT annotated assembly. These columns display the numbers of genes which are either «common to all IMGT annotated assemblies» or «Not common to all IMGT annotated assemblies».
The numbers of IMGT genes in the tables are provided per functionality (F for functional, O for ORF, P for pseudogene). If IMGT alleles for a given IMGT gene have different functionalities, these are concatenated (for example: 1 FOP).

Human (Homo sapiens) TRG alleles per subgroup (set or gene name) and functionality in IMGT annotated assemblies:

The table displays IMGT alleles identified for Human (Homo sapiens) TRG locus per subgroup and functionality (F, O, P) in IMGT annotated assemblies.
Sign # indicates IMGT genes which are not common to all IMGT annotated assemblies.
