In this work, the full-length hTERT gene was isolated and the sequence of the previously unknown region in intron 6 as well as that of upstream and downstream hTERT regions was determined. We have shown that intron 6 includes a variable number of tandem repeats (VNTR) of a 38 bp sequence,(hTERT-VNTR 6-1). Eight alleles of hTERT-VNTR 6-1 were identified among 103 unrelated individuals, ranging from 27 to 47 repeats. hTERT-VNTR 2-2 is another new 61 bp minisatellite repeat found in intron 2 of hTERT. At least four alleles of hTERT-VNTR 2-2 can be distinguished. Previous studies have described polymorphisms for minisatellites hTERT-VNTR 2-1, a 42 bp repeat in intron 2, and hTERT-VNTR 6-2, a 36 bp repeat in intron 6. These, together with another minisatellite found in intron 12, add up to five such structures within the hTERT gene. The segregation of hTERT minisatellites was analysed in …
