Database Description

PigGIS is a web-based depository of pig (Sus scrofa) genomic learning mainly engineered for biomedical research to locate pig genes from their human homologs and position Single Nucleotide Polymorphisms (SNPs) in different pig populations. It utilizes a variety of sequence data, including Whole Genome Shotgun (WGS) reads and Expressed Sequence Tags (ESTs), and achieves a successful mapping solution to the low-coverage genome problem.

Recent Developments

With the data presently available we have identified a total of 15.7 thousand pig consensus sequences covering 18.5 Mbp of the homologous human exons. We have also recovered 18.7 thousand SNPs and 20.8 thousand unique 60-mer oligonucleotide probes for future pig genome analyses.
