In all the patients, 53.8% (14/26) of the samples for hTERT, 73.1% (19/26) of those for pontin, 57.7% (15/26) of those for reptin and 53.8% (14/26) of those for dyskerin showed higher mRNA expression ratios (RQ>1) in tumour tissues than in normal tissues. This evidence concerns the gene DKC1 and neoplasm.
