I was looking into ClinVar data for getting mutation lists. There were mutations which were in the form GENE:c.*** representing they are CDS mutations and GENE:p.*** representing the amino acid changes.

What are those in the following forms represent?

  1. m.***
  2. GENE:n.***
  3. GENE:g.***
  4. nsv***

Example:

  • TBC1D24:c.1143-6C>T - CDS mutation
  • NP_002760.1:p.Cys139Ser - Protein mutation
  • m.1606G>A - ??
  • U43746.1:n.2241A>G - ??
  • NC_000023.11:g.53254331_53296102dup41772 - ??
  • nsv513787 - ??

They are the HGVS nomenclature.

The website is: http://www.hgvs.org/mutnomen/

But curiously, it is down right now.

Here is a cached copy.

As per the readme.txt on ClinVar ftp download site.
