The cause and cure for lupus are not known at this time. Researchers believe that lupus develops when a person with just the right combination of genes encounters triggers, either extreme or over an extended period of time. All of the genes have not been identified nor have all the triggers. Lupus is not directly inherited. In fact, there are cases of genetically identical twins where one develops lupus and the other does not. This supports the idea that it takes both genetic predisposition AND triggers. Daneil Wallace, MD provides a thorough discussion on this topic in The Lupus Book.
No, this is inherited.
Nephritis occurs in about 40-50% of systemic lupus erythematosus patients. If a person does not have lupus in the first place, then they will not develop lupus nephritis. Lupus itself is not directly hereditary. People inherit just the right combination of genes to presdispose them to developing lupus, but something has to trigger the autoimmune reaction. In studies of genetically identical twins lupus develops in both twins only 30% of the time, thereby demonstrating that lupus is not totally inherited.
Lupus is not contracted. Lupus develops. A person cannot catch lupus because it is not an infectious disease and it is not caused by any pathogen. The exact cause of lupus is not understood. At this point in time, scientists do know there is a genetic component but it is not directly inherited. If you have a first degree relative with lupus your chance of developing the disease is only 10% greater than the normal population. People who are genetically predisposed to develop lupus may or may not develop the disease. A trigger is needed to "turn on" the autoimmune response. Triggers include sunlight, cigarette smoke, and stress. Others are suspected.

Lupus is not caused by a pathogen. Lupus is not contagious.
is lupus infectious
20 percent of people with lupus will have a parent or sibling who already has lupus or may develop lupus.
Cutaneous lupus which is often called discoid lupus.
Lupus nephritis is one of the common (40%) complications of systemic lupus erythematosus. The other types of lupus are neonatal (affecting newborns), discoid or cutaneous (affecting the skin and hair), and drug induced (which subsides when the offending drug is withdrawn). If you have lupus nephritis, then you have lupus.
There are no immunizations for lupus because lupus is not contagious. Immunizations protect you from pathogens. Lupus is not caused by a pathogen, therefore there is no possibility of immunization.
Systemic lupus erythematosus. This is the most serious form of lupus and affects about 70% of all persons with lupus
There is no lupus gene. At this point, researchers have found 30 loci (locations) on the human genome that are implicated in the development of lupus.
