Researchers have studied a large number of families affected by psoriasis and identified genes linked to the disease. Also, a treatment that works very well in one person may have little effect in another. Psoriasis represents a complex disease at the cellular, genomic and genetic levels, with infiltration of many types of leukocytes into the skin, altered growth and differentiation of skin-resident cells, and altered expression of more than 1,300 genes in psoriatic lesions. There was a male preponderance with sex ratio of 1.4:1. Although the skin disease psoriasis was first recognized as a distinct disease as early as 1808 (1), its pathogenic mechanisms have eluded investigators for decades. One confounding aspect of psoriasis is its waxing and waning; its recurrence and regression, and the variable extent of body involvement. Only 10 of HLA-Cw6-positive individuals develop psoriasis, suggesting a major role for additional genes and/or environmental triggers.
Psoriasis: Symptoms, Pictures, Causes, And Treatments
A combination of elements, including genetic predisposition and environmental factors are involved. Defects in immune regulation are thought to play a major role. Yes, psoriasis is associated with inflamed joints in about one-third of those affected. Psoriasis is a common, chronic, relapsing, inflammatory skin disorder with a strong genetic basis. Twin studies support the role of genetic factors with a three-fold increase in concordance in monozygotic twins compared with fraternal twins. The most common areas affected are over elbows and knees, the scalp and the lower back. Inherited (genetic) factors seem to play a part, as about 3 in 10 people with psoriasis have a close relative also affected. Psoriasis is a long-term (chronic) scaling disease of the skin, which affects 2 3 of the UK population.

One type of white blood cell, the B-cell, begins creating antibodies that destroy normal skin cells. Diseases like Crohn’s, psoriasis, and eczema are all caused by defects in the same genes, reveals new study. According to the scientists behind the new study we are now one step closer to understanding the cause of these diseases, and this knowledge could lead to new types of treatment. When we conduct such a big study it gives us an opportunity to find even more genetic variants.
Plaque psoriasis (psoriasis vulgaris), the most common form of the disease, is characterized by small, red bumps that enlarge, become inflamed, and form scales. Age, general health, lifestyle, and the severity and location of symptoms influence the type of treatment used to reduce inflammation and decrease the rate at which new skin cells are produced.
