Psoriasis has a major genetic component. The chance of having psoriasis is about a 10 to 15 percent, if one of your parents has psoriasis. If both parents have psoriasis, the risk increases to 50 percent.
Nevertheless, If one of your parents or both suffers from psoriasis there is a higher change of you having psoriasis as a result of genetics, but this is not guarantee that you will develop the condition.
Similarly, a psoriasis flare during pregnancy will not increase the chance of a child developing psoriasis. It is most likely that if he/she is going to develop psoriasis, this will occur later in his/her life.
