Psoriasis is associated with HLA-Cw6, and Caucasians who carry this allele have about a 10-fold increased risk of developing psoriasis. We have HLA-C typed 369 patients with familial psoriasis and compared the clinical features of the patients carrying HLA-Cw6 against those carrying other HLA-C types. Some striking clinical differences were observed between the two groups. Patients who are Cw6 positive had a lower age at onset (p=3x10(-7)). Cw6-positive women had an earlier disease onset than Cw6-positive men (p =0.02), but such a difference was not observed for the Cw6-negative patients. The guttate-type onset of psoriasis was mostly confined to this group (p=2x10(-4)) and persistent disseminated guttate-like papules were also predominantly observed in the Cw6-positive patients (p <10(-)4). The Cw6-positive patients also had more extensive plaques on their arms, legs, and trunk (p =0.001), more severe disease (p =0.003), higher incidence of the Koebner's phenomenon (p =0.005), reported more often that their psoriasis got worse during or after throat infections (p =0.02), and more often a favorable response to sunlight (p =0.008) In contrast, dystrophic nail changes were more common in the Cw6-negative patients (p =0.002) and also psoriatic arthritis, although this was not significant (p =0.135). It is concluded that patients with psoriasis have different clinical features depending on whether they are HLA-Cw6 positive or negative.
