[HLA in psoriasis, population and family studies (author's transl)].

We have detected B13 and BW17, respectively 6 and 20 times, in a dample of 51 psoriasis, versus, respectively 2 and 12 times in a sample of 140 control subjects. Two informative families have been investigated. In the first one, marker transmission and illness heredity were correlated, whereas, in the second one, both were dissociated. These observations allow to consider every physio-pathologic hypothesis linking HLA system and psoriasis vulgaris.
