This could potentially reduce symptoms associated with seborrheic dermatitis as a study conducted by Bergbrant et al. indicated that the condition may be due to an immunological effect, reporting that of the 30 patients with seborrheic dermatitis, 14 had higher serum levels of IgA, while 11 patients had higher IgG antibody levels, and approximately 46% of patients expressed high levels of natural killer cells (66). The gene discussed is CD79A; the disease is seborrheic dermatitis.
