Is the genetic probability of ichthyosis high?

Ichthyosis is generally passed on to offspring through parents, and the heritability of ichthyosis is very high. After a large number of surveys and statistics, if both parents have ichthyosis, the genetic probability is as high as 80%. If one of the parents suffers from ichthyosis, the genetic probability is 50%. Therefore, if you find that you are a patient with ichthyosis, it is best to actively receive treatment. After cured patients, if they give birth to children, the genetic probability of ichthyosis is 30%.
