Re: Psoriasis: Is My Sister Inheriting It?
They know Psoriasis is a genetic disease but Docs are puzzled because the inheritance of it can seem random. It probably involves multiple genes or combinations of many genes.
They do know if one parent has psoriasis, a child has a 10 percent chance of developing psoriasis. If both parents have psoriasis, it's almost a 50 percent chance.
