Assessment of simple sequence repeats signature in hepatitis E virus (HEV) genomes.

ABSTRACT:

Background

Hepatitis E virus (HEV) is small (27-34 nm diameter) non-enveloped with positive sense ssRNA genome. Microsatellites or simple sequence repeats (SSR) are short tandem repeat sequences present across coding and non-coding regions of both prokaryotes and eukaryotes. They are involved with genome function and evolution at multiple levels.

Results

The complete genome sequences of 22 HEV genomes of the family Hepeviridae and genus Orthohepevirus (21 species) and Piscihepevirus (1 species) were extracted from NCBI database ( http://www.ncbi.nlm.nih.gov/ ). The extraction of microsatellites was done using Imperfect Microsatellite Extractor (IMEx) in 'Advance-Mode'. The average genome size of the studied HEV genomes was 7003nt and it ranged from 6649nt (HEV11) to 7310nt (
