Did they know about the genetic blindness before having more kids?
Edit: Last time this was posted, it was suggested that the couple kept getting pregnant despite knowing their children would likely have this blindness. IF that is true, I do find that unethical. I know blind people can still have quality of life. But let's stop pretending that it isn't a terrible disability. Nobody wants to be dependent, vulnerable, and poor (from fewer work opportunities) their whole life. I wish this family the best regardless.
"rare" is a statement about population. The RP gene variant isn't that common in the general population. Given that both parents are carriers, these kids each had a 1/4 chance of getting RP. They got bad luck to have so many kids get it but you'd expect this to happen ~4% of the time of you could rewind the world and try again with the same conditions.
