What causes Crohnâs? Causes of Crohn’s Disease. The causes of Crohn's disease are not known. Diet and stress were once believed to be responsible. However, we now know that these may aggravate the disease, but they do not cause it.Research suggests that a malfunctioning immune system, genetics, and environment may be factors in the development of the disease.mmune System. A main characteristic of Crohn’s disease is chronic inflammation. Inflammation is a normal immune system response to outside invaders such as viruses, bacteria, and parasites. Some researchers believe that Crohn’s disease may start as a normal response to an outside invader.

Tay-Sachs Causes Tay-Sachs disease is caused by the absence or significantly reduced level of a vital enzyme called beta-hexosaminidase. It is the Hexosaminidase A (HEXA) gene in the DNA that provides instructions for making this enzyme. Without the correct amount of the HexA enzyme, a fatty substance or lipid called GM2 ganglioside accumulates abnormally in cells, especially in the nerve cells of the brain.

- RDS is considered BPD when preemies still need oxygen therapy at their original due dates (past 36 weeks' postconceptional age). BPD also can be due to other problems that can affect a newborn's fragile lungs, such as trauma, pneumonia, and other infections. All of these can cause the inflammation and scarring associated with BPD, even in a full-term newborn or, very rarely, in older infants and children.

Huntington's disease Genetics of Huntington’s disease. Huntington's disease is caused by an altered gene. This gene is passed on from parent to child, but the condition isn’t obvious at birth. The symptoms usually, but not always, first appear when the person is approaching middle age. Huntington's disease is a slow, progressive condition that affects people differently.

Nonsteroidal Anti-inflammatory Drug (NSAID Athletes can develop second-degree heart block for the reasons discussed above. Some children born with congenital heart disease (heart defects present at birth) can also develop second-degree heart block. Other causes of second-degree heart block include: 1  damage that develops during a heart attack.2  Lyme disease – a bacterial infection spread by tics. number of medications can also cause third-degree heart block including: 1  digoxin. 2  calcium-channel blockers. 3  beta blockers – used to treat high blood pressure. 4  tricyclic antidepressants – an older type of antidepressant. 5  clonidine – used to treat a sudden, sharp rise in blood pressure (hypertensive crisis).

Mitochondrial disease Other causes of mitochondrial disease are mutations in genes of the nuclear DNA, whose gene products are imported into the mitochondria (mitochondrial proteins) as well as acquired mitochondrial conditions.itochondrial disorders may be caused by mutations, acquired or inherited, in mitochondrial DNA (mtDNA) or in nuclear genes that code for mitochondrial components. They may also be the result of acquired mitochondrial dysfunction due to adverse effects of drugs, infections, or other environmental causes (see MeSH).

Heart abnormality birth defects In around eight out of 10 cases, the reason for the congenital heart defect is unknown. Some of the known causes of CHD include: Genes – 20 per cent of cases have a genetic cause. Other birth defects – a baby affected by certain birth defects, such as Down syndrome, is more likely to have malformations of the heart. Maternal illness – illness of the mother during pregnancy (for example, rubella – now rare) may increase the risk of congenital heart disorders.

Carcinoid syndrome Carcinoid syndrome occurs in very few people with carcinoid tumors, after the tumor has spread to the liver or lung. These tumors release too much of the hormone serotonin, as well as several other chemicals. The hormones cause the blood vessels to open (dilate). This causes carcinoid syndrome.
