**What it does**

SIFT predicts whether an amino-acid substitution affects protein function,
based on sequence homology and the physical properties of amino acids.
SIFT can be applied to naturally occurring non-synonymous polymorphisms
and laboratory-induced missense mutations.  This tool uses SQLite databases
containing pre-computed SIFT scores and annotations for all possible nucleotide
substitutions at each position in the human exome.  Allele frequency data
are from the HapMap frequency database, and additional transcript and 
gene-level data are from Ensembl BioMart.

The input dataset must contain columns for the chromosome, position, and
alleles.  The alleles must be two nucleotides separated by '/',
usually the reference allele and the allele of interest.
The strand must either be in another column or all the same.
The output contains a standard set of columns plus the additional ones that
have been selected from the list above.
