Is Retinitis pigmentosa only inherited? For example, if my parents and both their parents' sides do not have it nor any relatives. is it possible the next generation could?
retinitis pigmentosa can be 'spontaneous' which means neither your parents had nor had the gene; or it can be inherited in any genetic method dominant, recessive, latent, variable penetrance.
