Here is a simple script (based on java/groovy) that does the following things for variant calls:

• Identifies parent gene segment (Exon/Intron/UTR)
• translates related codons (and identifies missense mutations)
• checks if variant is a known SNPs (dbSNP) or cancer-associated mutation (COSMIC)

The only prerequisite is an archive of refgene track (hg19) and latest (as of 2013) dbsnp/cosmic entries which goes with the distribution. Hope this will be useful
