Is psoriasis hereditary

summary

A friend recently suffered from psoriasis, itching to death. Unfortunately, his father also had severe psoriasis, so he doubted whether the disease could be inherited. Now let me introduce to you whether psoriasis is hereditary.

Is psoriasis hereditary

First: psoriasis is a common skin disease, but also a stubborn disease, its pathogenesis is very complex, so it is difficult to cure. According to expert research, psoriasis is hereditary.

Second: according to clinical findings, psoriasis patients often have a family history and genetic tendency. About 10-20% of psoriasis patients have family history. Now we think that heredity is the heredity of chromosome body gene, and the main cause is reactive oxygen species. Other factors: season, climate, environment, virus, infection, mental trauma, endocrine disorders, immunological abnormalities, etc.; all have a certain relationship, which can lead to the occurrence of psoriasis.

Third: psoriasis has a certain genetic tendency, which is not completely inherited. The incidence of monozygotic twins is higher than that of dizygotic twins. It has been reported that parents are normal, and their children are 11.9% of the disease. One of the parents is ill, and the incidence rate of their children is 18.4%. Both parents are suffering from this disease, and their children's incidence rate is increased to 70%, which is early and serious. The inheritance pattern is autosomal dominant inheritance with incomplete exons or autosomal recessive inheritance.

matters needing attention

In general, psoriasis can be inherited, but not all patients with psoriasis are infected through heredity, and it does not mean that all psoriasis will be inherited. There is a certain probability and a certain coincidence.
