What gene causes lupus erythematosus?

Many genes. The previous answer is right with several genes associated with lupus, but no one knows how those genes cause disease. I think it's important to remember that there is likely many ways to develop lupus symptoms, and this will vary between people. So some of these known genes will be important for some, and not important for others. As we sequence more patients, we'll have more answers.
Numerous genes. There are multiple genes found as the cause of lupus. One is a mutation in the trex1 gene. Other genes include: blk, itgam, pxk, kiaa1542, rs10798269, and bank1 and there are more than a dozen of other known combination of genes.

With acute diffuse proliferative glomerulonephritis caused by systemic lupus erythematosus, why would a patient have uremia and hyperkalemia?

SLE DPGN is bad. The degree of remaining renal function dictates the inability of the kidney to excrete waste products and manage potassium levels. In any severe kidney disease when egfr approaches 15 ml/min uremia and elevated k+ levels are frequently noted.
Lupus nephritis. This disorder results in the immune system attacking the kidney filters, leading to loss of kidney function. If severe enough, it can lead to build up of toxins that are normally removed from the blood by the kidneys, a condition known as uremia. Excess potassium from our diet is removed by the kidneys as well, so with damaged kidneys, potassium levels can become too high, called hyperkalemia.

Is there a cure for systemic lupus erythematosus (sle)?

Serious non-cancer. Lupus is a common multisystem autoimmune poorly-understood illness that is not cancer. It formerly killed many, if not most, of its victims. With today's treatments and a compliant, proactive patient, death is the exception. One of the most troublesome things is that lupus patients feel much sicker than they look, and this causes misunderstandings. Groups of fellow lupus-sufferers can help lots.
No, but. It is a serious illness that can shorten the life span of affected individual. Sle is an autoimmune disease and the body damages its own tissues and cells. It can result in multiple pathologies, including anemia, bleeding, arthritis, serositis, kidney disease etc. For more information please consult the website given below: http://www. Ncbi. Nlm. Nih.
