Question: psoriasis-is it genetic?


 doctoradvice - Sat Apr 19, 2008 9:43 am

Hello doctor,

I am 24 now and i live in india. my father is affected with chronic psoriasis for the past twenty years and he is undergoing treatment for it. But recently i also observe tiny black coloured lumps in my skin,followed by an allergic sensation on the skin,when i eat any kind of sea food especially fish. Also there is water discharge on the lump that is formed, and it leaves out black coloured patches like eruptions on the skin if i scratch it. I had applied an ointment by name 'flucort' and it is ok by now. But my doubt is, "Is this allergy a primitive sign of psoriasis? " And also please clarify that whether psoriasis is infectious? Because i sometimes get to use his towels or soaps occasionally. Is it ok or should i have to be alert not using them.
Does psoriasis spread genitically ? please advice.

User avatar Hello,
Like many other conditions it is believed there may be a genetic component that makes a person more susceptible to psoriasis than another person. Most believe that it is a series of conditions that are necessary for one to get psoriasis. Even this combination likely will differ from one person to another. Scientists believe that about 10% of people have the genetic susceptibility but only 2 - 3 % actually develop psoriasis.

This condition is not contagious. One person cannot pass it to another so you are safe on the towel question.

I hope this helps.

Best wishes,
Debbie
