What causes Urbach-wiethe?
Urbach-Wiethe disease is an autosomal recessive disorder caused by mutations in the ECM1 gene on chromosome 1, which encodes extracellular matrix protein 1 (ECM1) 1-3. ECM1 is a key structural component of basement membranes and the extracellular matrix, providing strength to tissues 4.
What is Urbach white disease?
Urbach-Wiethe disease (UWD) is an extremely rare autosomal recessive disorder characterized by mutations in the extracellular matrix protein 1 gene on chromosome 1. Typical clinical manifestations include voice hoarseness in early infancy and neuropsychiatric, laryngeal, and dermatological pathologies later in life.
How do you get Urbach-Wiethe disease?
The disease is caused by loss-of-function mutations to chromosome 1 at 1q21, the extracellular matrix protein 1 (ECM1) gene. The dermatological symptoms are caused by a buildup of a hyaline material in the dermis and the thickening of the basement membranes in the skin.
Which part of the brain is affected by Urbach-Wiethe disease?
(1994, 1995) investigated a patient suffering from Urbach–Wiethe (UW) syndrome, a very rare autosomal recessive disease, which produces bilateral calcifications in the anterior medial temporal lobes, especially of the amygdalae, in 50–75% of cases (Newton et al., 1971; Staut and Naidich, 1998).
What is Urbach-Wiethe disease?
Urbach-Wiethe syndrome is a rare autosomal recessive disorder predisposing to increased collagen deposition in the skin and soft tissues. Characteristic features include monoliform blepharosis, ankyloglossia and bilateral symmetric basal ganglia calcification.
Is there a cure for Urbach-Wiethe disease?
There is currently no cure for lipoid proteinosis (LP) of Urbach and Wiethe. Treatment is based on the signs and symptoms present in each person. The skin abnormalities found in people affected by LP may be treated with certain medications, including corticosteriods, dimethyl sulfoxide; or d-penicillamine.
Can you be born without fear?
SM has an unusual genetic disorder called Urbach-Wiethe disease. In late childhood, this disease destroyed both sides of her amygdala, which is composed of two structures the shape and size of almonds, one on each side of the brain. Because of this brain damage, the woman knows no fear, the researchers found.
What causes fearlessness?
Fear starts in the part of the brain called the amygdala. According to Smithsonian Magazine, “A threat stimulus, such as the sight of a predator, triggers a fear response in the amygdala, which activates areas involved in preparation for motor functions involved in fight or flight.
What is it called when you have no fear?
You can use the adjective unafraid for anyone who acts in a fearless or brave way, or who feels no anxiety.
Which part of the brain controls fear?
the amygdala
Many of their studies begin with the amygdala, an almond-shaped structure that is considered the hub for fear processing in the brain. While the amygdala was once thought to be devoted exclusively to processing fear, researchers are now broadening their understanding of its role.
What do you call a person who isn’t afraid of anything?
fearless. adjective. showing approval not afraid of anyone or anything.
When was Urbach Wiethe disease first reported?
Urbach–Wiethe disease. Urbach–Wiethe disease is a rare recessive genetic disorder, with approximately 400 reported cases since its discovery. It was first officially reported in 1929 by Erich Urbach and Camillo Wiethe, although cases may be recognized dating back as early as 1908.

How does Urbach–Wiethe disease affect the nervous system?
Therefore, Urbach–Wiethe disease patients with calcifications and lesions in these regions may suffer impairments in these systems. These calcifications are the result of a buildup of calcium deposits in the blood vessels within this brain region. Over time, these vessels harden and the tissue they are a part of dies, causing lesions.
What are some books about Urbach-Wiethe disease?
Urbach–Wiethe disease is used as the main plot element in a 2013 Dutch novel, De angstjager (The Fear Hunter) by author Joris van Os. Released in 2015, A Fearless Life by author Joshua McCloskey is about a young woman’s life living with Urbach-Wiethe.
