Genetic testing for psoriasis
Psoriasis is a chronic immune disorder which affects 3% of the population. It is a typical immune disease. Psoriasis affects the entire skin cell cycle, making the skin cells divide at a higher rate as they normally do. Many risk factors for the appearance of this disease are known, the most important being the family history of the disease. This indicates an important genetic component to the disease.
Why should you have your DNA analysed for predisposition to psoriasis?
By analysing your genome, we test the genes of the HLA region which is linked to psoriasis and at the same time responsible for correct functioning of the immune system. Naturally, in addition to the HLA region, other regions are tested which have been shown to be linked with psoriasis.
How is psoriasis prevented or treated?
The disease appears cyclically and lasts for weeks or months, followed by remissions. The typical skin change in psoriasis are islands of skin with a red base and silver scales. Changes in nails and joints are also observed. To diagnose the disease, a careful expert dermatological skin examination usually suffices; in case of doubt or to confirm the diagnosis, a skin biopsy can also be performed. The treatment of psoriasis is directed towards terminating the immune response and thus halting the increased skin cell division.
