PupaSuite is an interactive web-based SNP analysis tool that allows for the selection of relevant SNPs within a gene, based on different characteristics of the SNP itself, such as validation status, type, frequency/population data and putative functional properties (pathological SNPs, SNPs disrupting potential transcription factor binding sites, intron/exon boundaries...). Also, PupaSuite provides information about LD parameters (based on genotype data from HapMap) and identifies haplotype blocks and tag SNPs (using the Haploview program).

PupaSuite operates with a collection of entries of dbSNP mapped to the Golden Path genome assembly, as implemented in human section of Ensembl (Hubbard T. et al., 2005).
