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.

But curiously, it is down right now.
