Is psoriasis genetic?
2 doctors weighed in across 2 answers
Yes: There are genetic causes of psoriasis, but it also can occur in people who have no history of relatives with psoriasis. There are also certain medications that can actually be associated with developing psoriasis.

Clearly genetic!: Major hla genes, which are inherited in an autosomal dominant pattern, increase the likelyhood of psoriasis and psoriatic arthritis. The are hla-b17 (now 57 & 58), cw6, b13, b37, 38, and 39. These do not skip generations if inherited. In my patients, i find almost always direct generational linkage!
