Know that autoimmune diseases work in families. Current analysis points to a genetic component in autoimmune diseases. Nevertheless, autoimmune diseases aren’t typical genetic illnesses like, for instance, sickle cell anemia, where there is a specific gene mutation. With autoimmune diseases, multiple genes are participating that collectively boost vulnerability or susceptibility. Thus, what’s inherited is not one particular gene but several genes that increase risk. As a result, autoimmune diseases have a tendency to ‘cluster’ in family members – not as a definite disease, but as a general tendency to the autoimmune procedure and, as a result, different autoimmune diseases.
