Hi Thanks for your query Based on your query 1. Yes psoriasis can be inherited. There are proven genetic mutations in twins. It can also be passed on to offspring from parents. But that does not mean a child will get for sure. As there are multiple factors to decide in a genetically susceptible individual, its difficult to commit on the sureness of manifesting with disease. 2.There are options of genetic testing for psoriasis in parents and also prenatal. 3. Fear of getting disease in offspring should not prevent you from going for another child. You can go for prenaral counselling and discuss the options for further course of action. Hope this helps. Regards
