Psoriasis Keys Are Found in Your DNA

Did you know that around 3% of the national population develops psoriasis? Scientists think that around 10% of the population has inherited genes that can lead to developing psoriasis. 

Genes Cause Eventual Psoriasis Diagnosis

Research regarding this gene began back in the 1970s, but science has recently started to uncover more information due to advances in genetic technology and increased funding. According to the National Psoriasis Foundation, The BioBank will bring the world’s largest collection of psoriasis-related DNA to qualified researchers. Scientists and researchers have identified around 25 genetic variants that can make someone more likely to develop a psoriatic disease. They have also identified several spots in the human genome where multiple genes may be involved in psoriasis and psoriatic arthritis

Psoriasis Triggers

Triggers are unique per person. What triggers someone’s psoriasis may not be what brings on an attack for someone else. Possible triggers include:

  • Stress that leads to a flare-up or aggravating an existing flare up.
  • Skin injuries that bring on a flare-up where the skin has been injured or traumatized by a scratch, sunburn, etc. This is referred to as the Koebner phenomenon.
  • Medications associated with flares are lithium, antimalarials, Inderal, quinidine, and Indomethacin.
  • Infection by anything that can affect your immune system, particularly strep throat.

Some people even attribute their flare-ups to unproven triggers like the weather.

Psoriatic Arthritis

Psoriatic arthritis affects up to 30% of people with psoriasis. It usually affects the distal joints and can cause swelling, stiffness, joint pain, and overall fatigue.

The sooner you catch and treat psoriasis, the better success you will have with managing and relieving your pain and inflammation, as well as preventing joint damage. Research has shown that delaying treatment can cause permanent joint damage.
