RP3 affects mostly men, causing them to become blind by the age of thirty. Symptoms develop in early childhood. If a boy has trouble seeing anything at night or begins to see with tunnel vision, this indicates a possibility the individual contains a defected RP3 gene. Keep an eye on your young male children.
I am amazed at the discovery of RP3. An average of 1 in 2000 people suffer from blindness; and since the gene, a major cause, has been discovered, a treatment may be devised within the upcoming years. For now, scientists can only genetically determine an individual's susceptibility.
