[Conjugal psoriasis and its relation to histocompatibility antigens. A family study]. / Konjugale Psoriasis und ihre Beziehung zu den Histokompatibilitätsantigenen. Eine Familienuntersuchung.

The higher risk of the occurrence of psoriasis vulgaris in the progeny of conjugal psoriasis marriages was repeatedly reported. In this paper a family, where the parents and both the children are suffering from psoriasis is described. The disease occurs also in some of the blood relatives of the father and mother. The occurrence of the disease and the segregation of the HLA antigens was followed in the kinship. It seems that a genetic factor linked to the HLA system influences the developement of psoriasis vulgaris.
