Kaviar (~Known VARiants) is a simple tool for answering a specific question:
What variants have been reported for a range of genomic locations?
1. Specify the coordinate systemHuman reference version (freeze) is
Input coordinates are   Output coordinates are
2. Specify your queries
Enter genomic positions or ranges, or dbSNP rsids
You can use a variety of supported formats.
Chromosome: (e.g. "chr1", "chrX", "17")
Coordinate(s): (e.g. "714019-714033", "77119, 555911,714019")
Alternatively, list coordinates (e.g. paste here from Excel a list of chromosome : position coordinates and/or rsids like rs10136372):
...or upload a text file with the coordinates:
3. Specify filtersMAF (table/text/JSON output only):    Min   Max
Variant type(s):
4. Specify the output formatPreferred output format:
