Contig reference residue from the translated XP_ protein. Position
is given on the protein sequence.
Residue on the contig reference, variant residue specified by one
or more alleles for a variation record in dbSNP (synonymous or nonsynonymous),
or the corresponding residue on the neighbored protein with structure
Position of the variant amino acid on the protein sequence with structure
information. The alignment between the contig protein and its neighbor
structure can be viewed in Cn3D or by selecting the 'view alignment'
Check box to include the selected variation in the set of highlighted
positions in the Cn3D export file.
