Retinitis Pigmentosa Fact #23
So, I've already told you that RP is a hereditary disease and I listed the different ways the gene can be passed from generation to generation. I found some percentages on the different ways of inheritance. 20-25% of patients get it through autosomal dominant, 15-20% get it through autosomal recessive, 5-10% is X related, and the remaining 45-50% have no known relatives with the mutation.

With this said I now have a question. Why is RP considered a hereditary thing when a majority of patients diagnosed with it have no known relative with the faulty gene? So, I have a question for those of you who read my blog and have been diagnosed with RP or a different kind of degenerative disease. Is your degenerative disease hereditary or are you part of the 50% who have no known traces of it in your family?
