What happens with genes when psoriasis is involved?

In psoriasis, genetic factors play a significant role in its development, as the condition has a strong hereditary component. Specific genes, particularly those related to immune system function and skin cell turnover, are often implicated in psoriasis. These genetic predispositions can lead to abnormal immune responses, causing inflammation and rapid skin cell proliferation characteristic of the disease. Environmental triggers can also interact with these genetic factors to initiate or exacerbate psoriasis symptoms.
