Summaries for Mitochondrial Encephalomyopathy Lactic Acidosis and Stroke-Like...

NIH Rare Diseases : 54 Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) affects many parts of the body, particularly the brain and nervous system (encephalo-) and muscles (myopathy). Symptoms typically begin in childhood and may include muscle weakness and pain, recurrent headaches, loss of appetite, vomiting, and seizures. Most affected individuals experience stroke-like episodes beginning before age 40. People with MELAS can also have a buildup of lactic acid in their bodies that can lead to vomiting, abdominal pain, fatigue, muscle weakness, and difficulty breathing. The genes associated with MELAS are located in mitochondrial DNA and therefore follow a maternal inheritance pattern (also called mitochondrial inheritance). MELAS can be inherited from the mother only, because only females pass mitochondrial DNA to their children. In some cases, MELAS results from a new mutation that was not inherited from a person's mother.

MalaCards based summary : Mitochondrial Encephalomyopathy Lactic Acidosis and Stroke-Like Episodes, also known as melas syndrome, is related to growth hormone deficiency and pituitary gland disease. An important gene associated with Mitochondrial Encephalomyopathy Lactic Acidosis and Stroke-Like Episodes is GHRH (Growth Hormone Releasing Hormone), and among its related pathways/superpathways are NF-KappaB Family Pathway and G-protein signaling RAC1 in cellular process. The drugs Melatonin and Vaccines have been mentioned in the context of this disorder. Affiliated tissues include brain, skin and pituitary.

Genetics Home Reference : 26 Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) is a condition that affects many of the body's systems, particularly the brain and nervous system (encephalo-) and muscles (myopathy). The signs and symptoms of this disorder most often appear in childhood following a period of normal development, although they can begin at any age. Early symptoms may include muscle weakness and pain, recurrent headaches, loss of appetite, vomiting, and seizures. Most affected individuals experience stroke-like episodes beginning before age 40. These episodes often involve temporary muscle weakness on one side of the body (hemiparesis), altered consciousness, vision abnormalities, seizures, and severe headaches resembling migraines. Repeated stroke-like episodes can progressively damage the brain, leading to vision loss, problems with movement, and a loss of intellectual function (dementia).
