Map genetic variants to protein domain/structure

[entrez]

I got some genetic mutations or variants from exome sequencing data analysis. I am trying to map genetic mutations/variants to protein domain/structure. Ideally, I want to visualize the variants in linear protein domain diagram and 3D protein structure like this figure. I did research, but I can’t find good tools/databases for such work.

I know similar questions have been asked here like https://www.biostars.org/p/61049/. But it is only the protein domain diagram (with no 3D structure), plus the protein domain annotation there seems to be limited.
This question was asked at biostar: https://www.biostars.org/p/125929/. But I want to check if anybody here may have a answer/hint. Thanks!

PyMOL should be able to show these changes for 3D structures (provided a structure is available in PDB): http://pymol.org/ If your institution does not have a license then you may be able to use "education" version (if you qualify): http://pymol.org/educational/

Thank you, Pymol looks like a good tool. Will try it out for the 3d structure.
Anyone knows database and visualization tools for mapping genetic variants to protein domains?
