<p>I'm a beginner bioinformatics student. I am currently working on my first project. We have gathered data about SNPs that are associated with a particular disease. We aim to understand the functional and structural implications of these SNPs. I have run mutagenesis on Pymol and gathered data on the variation in Hydrogen bonds.
We are now unsure how to analyze this data or interpret the mutagenesis result to get to a point where we can say that:</p>
<ol>
<li>A particular structural change is occurring and</li>
<li>This change is now leading to functional changes thereby making it pathogenic.</li>
</ol>
<p>Is it just basic understanding? Or are there any other software tools to help with this interpretation?</p>
<p>Thanks in advance!</p>

Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking.

Is this human data?

How to interpret mutagenesis results from pymol to make conclusions about structural/functional changes and predict resulting pathogenesis?
# How to interpret mutagenesis results from pymol to make conclusions about structural/functional changes and predict resulting pathogenesis?

(Asked by: username_0 on 2024-07-22)

I'm a beginner bioinformatics student. I am currently working on my first project. We have gathered data about SNPs that are associated with a particular disease. We aim to understand the functional and structural implications of these SNPs. I have run mutagenesis on Pymol and gathered data on the variation in Hydrogen bonds.
We are now unsure how to analyze this data or interpret the mutagenesis result to get to a point where we can say that:

1. A particular structural change is occurring and
2. This change is now leading to functional changes thereby making it pathogenic.

Is it just basic understanding? Or are there any other software tools to help with this interpretation?

Thanks in advance!

Assuming this is human data, this seems like a job for the [Ensembl Variant Effect Predictor (VEP)](https://ensembl.org/info/docs/tools/vep/index.html):

If you can get your data into VCF format, you should be able to run VEP on it, which will tell you if there is a protein change, and whether that change is predicted to have a biological consequence.

Aside on terminology: in bioinformatics, when the term *structural change* is used, it usually refers to large-scale genetic changes (e.g. large deletions, translocations, insertions, or inversions). As SNPs are single point variations, they don't pass the threshold for structural change.
