Abstract
The hTERT gene encoding a catalytic subunit of human telomerase contains four blocks of variable number of tandem repeats (VNTRs) – two in intron 2 and two in intron 6. The segregation of hTERT VNTRs was analysed in families, revealing that all of them were transmitted through meiosis following a Mendelian inheritance. The work reports a further characterization of the minisatellites in hTERT. We employed transformation-associated recombination (TAR) cloning to isolate parental hTERT alleles and determined the specific combination of minisatellites at each of the polymorphic sites. A long-range haplotyping of hTERT determined by TAR cloning was verified by classical Mendelian analysis. Since such a strategy can be applied for any chromosomal locus, we conclude that recombinational gene capture could greatly facilitate haplotypes analysis.
