A scan of Sam's genome for the 100 most common mutations known to cause RP didn't find anything. How can you explain this result?

Answer:

He is either not carrying the gene for RP or the RP gene has mutated.

Step-by-step explanation:

RP or Retina Pigmentosa is an eye defect inherited by a person from a parent. The disease is degenerative as the individual gradually loses his sight. It normally starts off as night-blindness and could go as bad as a total loss of sight.

The mutation of both the RPGR and RP2 genes which are responsible for the function and structure of light-reception in the eye accounts for most cases of Retina Pigmentosa disease.
