title: Surprisingly little polymorphism in the merozoite-surface-protein-2 (MSP-2) gene of Indian Plasmodium falciparum.
abstract: The polymorphism in the merozoite-surface-protein-2 (MSP-2) gene of six Indian Plasmodium falciparum isolates was studied by PCR amplification, cloning and sequencing. One of the isolates showed a deletion of 63 bp and all showed point mutations, although some of these mutations were silent. All the isolates also exhibited 5' and 3' conserved regions, with the two 32-mer amino-acid repeats characteristic of the FC27 family, and none belonged to the IC-1/3D7 family. Although the MSP-2 genes of these isolates represent new allelic sequences, they belong to the FC27 family and show remarkably little variation.
