It is not infectious, therefore you cannot catch psoriasis from someone else. It does not scar the skin although sometimes it can cause a temporary increase or reduction in skin pigmentation. Both inherited and environmental factors play a role in the development of psoriasis. The pathogenesis of psoriasis is not fully understood, but population and twin studies suggest a large heritable component to the etiology. Genetic anticipation was also apparent and most marked if the disease was inherited from the father. Psoriasis is a long-lasting autoimmune disease characterized by patches of abnormal skin. The cause of psoriasis is not fully understood, but a number of theories exist. Psoriasis has a strong hereditary component, and many genes are associated with it, but it is unclear how those genes work together.
Given that psoriasis has characteristics of an autoimmune disease, it is not surprising that HLA studies revealed an association with certain alleles, notably HLA-Cw6. Despite this HLA component, psoriasis in some families is inherited as an autosomal dominant trait with high penetrance. Is psoriasis hereditary? No, psoriasis is not currently curable. Although psoriasis is not contagious from person to person, there is a known hereditary tendency. Without beating around the bush, researchers have proven that certain flakers are genetically predisposed to having psoriasis. So, like passing on genes for blonde hair or brown eyes, you could pass on a bit of DNA to your kids that increases their susceptibility to having psoriasis.
Having psoriasis does not affect your chances of getting pregnant. All of us carry hereditary genes from our ancestors and parents that are then passed on through our children, these play a part in our eye, hair colouring, skin types, characters, a whole range of things, including carriers for illnesses. I’m still not convinced that p is hereditary but I’m not convinced that it isn’t either. It seems more likely to me that psoriasis passed genetically ALONE would occur at a younger age. However if you ask is psoriasis hereditary- yes is the likely answer. Though psoriasis is inherited it is not passed on from parents to their children in a simple manner like that of hair color.
The Genetics Of Psoriasis: A Complex Disorder Of The Skin And Immune System
Psoriasis and the rare hereditary blistering disorders collectively called epidermolysis bullosa owe their distributions to local trauma; lesions that show a predilection for the elbows, knees, and lower back are common in psoriasis, and those found in the hands, feet, knees, and mouth of children are indicative of epidermolysis bullosa. Although the mechanisms of inheritance are not clear, psoriasis, like atopic dermatitis, has been thought to be inherited as an autosomal dominant trait that pursues a chronically remitting and relapsing course. Plaque psoriasis is the most common type of psoriasis. There is now no question that psoriasis is an inherited systemic inflammatory disease of immune dysfunction whose most obvious clinical feature is plaque of elevated, inflamed skin. EMedicineHealth does not provide medical advice, diagnosis or treatment. It is generally accepted by medical researchers that a hereditary component of psoriasis exists, as approximately 1 in 3 patients with the condition has a close family member that also suffers from the condition. The mechanism of these genes in the pathology of the condition varies and is not completely understood, but may affect the signaling proteins for inflammation. The genes responsible for psoriasis do not act independently. Environmental and other unknown causes affect its development too. Some of the genes involved affect the immune system, while others affect various components of the skin. Chronic plaque psoriasis can be itchy but it does not usually cause too much discomfort. It may be that some factor in the environment (perhaps a virus) may trigger the condition to start in someone who is genetically prone to develop it. About 1 person in 10 with psoriasis develops psoriatic arthritis. (About 2 in 100 people develop psoriasis at some stage in their life. However, it is not a straightforward hereditary condition. It is thought that a virus or other factor in the environment may trigger the immune system to cause the inflammation in people who are genetically prone to it.
Psoriasis Fertility, Conception And Pregnancy
As with other autoimmune diseases, researchers think some people may be genetically more likely to develop RA. They also theorize that there are environmental factors, such as viruses or bacteria that trigger this faulty autoimmune response. Accordingly, the psoriasis is not a hereditary disease in the narrower sense, but the predisposition to psoriasis may well be hereditary. However, there is the inheritance of psoriasis are still many unanswered questions. However, you should know that psoriasis is not merely what it seems. In reality, it is one of the chronic diseases of immune system disorder still under research even until today.
