3 Autoimmune Diseases Share a Genetic Defect, Scientists Find

(note:SI won't post entire article - see link)

Scientists have found an unexpected genetic link among three common autoimmune diseases: psoriasis, rheumatoid arthritis and systemic lupus erythematosus.

The link among the three diseases involves a protein that helps the thymus gland train cells of the immune system. Autoimmune diseases are caused when such cells mistakenly attack the body's own tissues.


The protein, Runx-1, controls the activity of various genes by binding to a nearby site on the DNA of the chromosomes. Last year, scientists at the University of Uppsala in Sweden reported that many patients with systemic lupus had an altered Runx-1 binding site on Chromosome 2, meaning that the Runx-1 protein could not properly control the gene next to the binding
