The CD8+ cell group (n = 7) obtained 1.40 × 10^5 annotated nucleotide sequence reads and 1.17× 105amino acids sequences, the data of sarcoidosis tissue group is 4.0 × 10^4 annotated nucleotide sequence reads and 3.0 × 10^4 amino acids sequences respectively. This evidence concerns the gene CD8A and sarcoidosis.
