A 40-kilobase subtelomeric region is common to most Plasmodium falciparum 3D7 chromosomes.

Starting from previous evidence indicating that some features are shared by several Plasmodium falciparum chromosomal extremities, a subtelomeric region present on most P. falciparum 3D7 chromosomes has been mapped. It was shown to occupy about 40 kb, and to include the proximal portion of pPftel. 1, the only telomeric clone described for P. falciparum [12], the complete 21-bp repetitive cluster and some conserved sites (PstI, EcoRI) proximally located with respect to this cluster.
