Insertion/deletion frequencies match those of point mutations in the hypervariable regions of the simian immunodeficiency virus surface envelope gene.

Abstract excerpt

A method for encoding insertions and deletions (indels) has been developed and adapted to the SplitsTree program. Following phylogenetic reconstruction, the relative frequencies of indels were estimated for a large number of in vivo sequence sets corresponding to the env V1 hypervariable region of the simian immunodeficiency virus SIVmac251. The method allowed recovery of many point mutations hitherto lost due to...
