Riddle of the task
Previously on "The Tale of Sir Binfo": Link
After careful thinking you finally decide which Symbol to push and then... nothing...
Did you push the wrong button? What if you're trapped forever? ...But suddendly you hear a loud noise. The sound of stone grinding on stone. A trapdoor opens in the floor and reveals a dusty stairway into the darkness below. As you enter it, magical torches on the walls of a long corridor spring to life and lighten your way. The cobwebs and stale air tell you that this way has been unused for a long time.
After a few minutes the hallway suddenly ends and you stand before a giant door. At least that's what you think it is as you can't find a doorknob or anything else to open it. The only thing you see is a strange circle of runes and a text beside it:
Here we stand. Undefeated, undivided.
We guard this door until united.
Though only one can break us all, for he is King.
It seems like you could move the two outer rings of runes (separately). Maybe some kind of combination lock?

Protocol
A protocol with a description of the data acquisition and other scripts used for this task is available here.
HGMD
SNP statistics for HFE in HGMD (non-professional):
- Missense/nonsense: 24
- Splicing: 3
- Regulatory: 1
- Small deletions: 4
- Small insertions: 1
- Small indels: 0
- Gross deletions: 2
- Gross insertions/duplications: 0
- Complex rearrangements: 1
- Repeat variations: 0
- Total: 36
The alignment between the sequence (NM_000410.3) used by HGMD and the uniprot sequence for Q30201 had 100% identity. Thus the SNP positions don't have to be adjusted.
The missense/nonsense SNPs can be found here.
dbSNP
SNPdbe
We've searched SNPdbe with NP_000401 and Q30201 for SNPs in the human genome and it listed 35 and 26 results respectively. Some of these hits overlapped though. This resulted in 46 unique SNPs. Both querry sequences have an identity of 100% with each other.
The SNPs can be found here.
