The incident puzzled doctors .. Jenin transferred to his mother a serious illness and caused the death

Caused by a hereditary factor of father and mother was healthy before pregnancy

A woman died of a rare type of dementia while she was pregnant with her son, according to the Daily Mail newspaper, while it was thought that the disease was due to a genetic factor of the father .

According to the source, the deceased woman's husband has also died of the disease "Kreutzfeld Jacob", which is caused by a degenerative brain disorder resulting in dementia and death.

Doctors were puzzled to learn that they were healthy and relieved of symptoms of the disease before pregnancy, but the fetus was transferred to the inherited disorder of the father, according to the website "Sky News Arabia" .

The woman's son is suffering from "Croatsfield Jacob" and the symptoms of the disease have appeared in the 53-year-old man.

The researchers are now likely to have inherited the gene responsible for the father's disease and then transferred it to the mother while he was fetus in the uterus.

Doctors say that the cells in the embryo contained toxic proteins that crossed the placenta, circulated in the blood and infiltrated the brain.

The Copenhagen Reference Center for Crohn's Disease in Copenhagen, Denmark, is particularly important because of its ability to detect a new cause of dementia.
