In addition, the high expression of FAM83A/B/C/D/F/H mRNA is associated significantly with shorter overall survival (OS) in patients with lung cancer, and the specificity/sensitivity of FAM83A, FAM83C, and FAM83H proteins in the diagnostic ability of death were found to be 0.9475/1,0.971897/1 and 0.9454545/0.8974359, respectively. This evidence concerns the gene SACK1A and lung cancer.
