Plaque psoriasis is a chronic disorder that leads to the quick accumulation of skin cells. This may result in scaling on the surface of the skin. It is quite common to notice redness and inflammation in the affected areas. These spots may bleed, crack, or develop red and thick patches. The condition tends to affect joints, especially knees and elbows. However, other parts can be affected, such as the face, scalp, neck, feet, and hands. Read on to learn more about common causes of plaque psoriasis.
1Genetics
The biggest risk factor for plaque psoriasis is family history. Indeed, more than 30 percent of the reported cases have at least one family member with the condition. The risk tends to be higher when the disease occurs to both parents. Currently, researchers have not identified the genetic links. However, they have found out some areas on a gene linked to symptoms of plaque psoriasis. People with this condition are more likely to have a chromosomal mutation of the gene. More research is needed in the future to break the genetic code, which can help reduce the risk. [1]
