Esterase D phenotypes in psoriasis vulgaris, atopic diseases and healthy controls.

Esterase D phenotypes have been determined in 162 patients with psoriasis vulgaris, 181 patients with atopic diseases and 110 healthy controls. All these samples are from the area of Rheinland-Pfalz (West Germany). The two patient samples show somewhat higher frequencies of Es D 1 and lower of Es D 2-1 phenotypes as compared to controls. These differences are, however, statistically not significant. The Es D1 frequency in controls (0.9045) is in accordance with those reported from other European populations.
