Is psoriasis heritable and is psoriasis hereditary? What is the probability of heredity?

Psoriasis has a certain chance of being inherited. In general, if both parents are psoriasis patients, the incidence of children is 50 66; If only one parent is psoriasis, the incidence is about the same.

The existence of a genetic component to psoriasis is now well recognized, which is confirmed by three studies: First, the same number of patients with clinical manifestations and a family member with psoriasis, i.e. a genetic genealogy survey. According to domestic and international surveys, about 10%-30% of patients have a family history of disease

Among the 943 patients surveyed in the long-term follow-up survey, 279 patients had a family history of disease, accounting for 32 people with three consecutive generations of disease, and 8 out of 25 people with blood relations in one family of three generations, but such families are very rare after all. The second is to investigate and study the incidence of psoriasis in twins. The third is the study of white blood cell blood type, which also proves that psoriasis has a genetic factor.

But the genetic probability can also be reduced, to reduce the genetic probability need to pay attention to two aspects, the first is to be stable and stop the drug for more than half a year without ** in the case of pregnancy, second, in the summer psoriasis reduction season pregnancy, if both have, it is the best, as long as the positive and correct**, are curable, will not affect normal life, although there are many places and drugs at present, but most of them can not make the patient get thorough**, **psoriasis conventional drugs can generally be cured, But it is still **, all the psoriasis toxins in the blood must be discharged in order to achieve the purpose of **. In addition, psoriasis patients should remember not to use hormones**, if they do, they will relieve the symptoms for a while, but eventually the condition will get worse and worse, and they can't**.

Psoriasis is a chronic ** disease, non-contagious, but there is a certain genetic predisposition! And there is currently no way to diagnose psoriasis in the fetus of pregnant women! If you plan to have children, you should fully understand the genetic aspects of psoriasis and weigh the pros and cons from the perspective of eugenics.

Make your choice at the end! But if you decide to do so, how long you can stop taking the drug before you get pregnant depends on what you've been on before**! Here are the genetic odds for people with psoriasis.

Psoriasis has a certain genetic predisposition, not completely hereditary. According to expert reports, both parents are normal, and children suffer from this disease; If one of the parents is sick, the incidence of the disease in the children is; Both parents suffer from the disease, and the incidence increases to 70% in their children. Now it is believed that heredity is the inheritance of chromosomal body genes, and the main cause is reactive oxygen species.

Other factors: season, climate, environment, virus, infection, mental trauma, endocrine disorder, immunological abnormalities, etc.;

All have a certain relationship, all of which can lead to the occurrence of psoriasis. All of the above are predisposing factors for psoriasis.
