Figure 1.

Schematic representation of the various changes observed in the coding regions (green arrows) affected by microsatellite indel mutations. In this illustration a hypothetical microsatellite tract (AT)₅ has been shown to undergo an indel of one repeat unit causing fission/fusion, premature termination and length variation of ORFs. The bi-directional arrows (black) indicate reversible nature of the microsatellite mutations.
