Detailed answer

Psoriasis is known to have a genetic component. It has been found that certain genes are associated with an increased risk of developing psoriasis. These genes are involved in the immune system and skin cell growth. Having certain variations in these genes can make a person more susceptible to psoriasis. However, it is important to note that not everyone with these genetic variations will develop the condition and other factors such as environmental triggers also play a role in its development.
