Chromosome 7 gene summary. TCRB encompasses 67 gene and 16 pseudogene segments. TCRG includes 14 gene segments and 8 pseudogene segments. NCBI Refseq and Ensembl use different criteria; for comparison, we have grouped similar categories in the same row. The complete list of genes is at www.chr7.org/, and it will continue to be updated.
| Categories of genes | No. of genes | Gene length (bp) | Transcript length (bp) | Exon size (bp) | No. of exons per gene | CpG islands (−2000 to 1000 bp) | No. of chromosome 7 genes from other projects |
