SequenceVariantAnalyzer (SVA) is a computer program for annotating and analyzing genetic variants called (identified) from a whole genome or exome sequencing study (Shotgun sequencing).

Background
DNA sequence information underpins genetic research, enabling discoversies of important biological or medical benefit. Compared with previous discovery strategies, a whole-genome sequencing study is no longer constrained by differing patterns of linkage disequilibrium, thus, in theory, is more possible to directly identify the genetic variants contributing to biological traits or medical outcomes.
The rapidly evolving high-throughput DNA sequencing technologies have now allowed the fast generation of large amount of sequence data for the purpose of performing such whole-genome sequencing studies, at a reasonable cost. SequenceVariantAnalyzer, or SVA, is a software tool to analyze the genetic variants identified from such studies.
Functions
SVA is designed for two specific aims:
(1) To annotate the biological functions of the identified genetic variants and group them, conveniently;
(2) To find the genetic variants that are associated with or responsible for the biological traits or medical outcomes of interest.
Language
SVA is developed on the Java platform.
