What causes Clouston syndrome?
Clouston syndrome is caused by mutations in the GJB6 gene. This gene provides instructions for making a protein called gap junction beta 6, more commonly known as connexin 30. Connexin 30 is a member of the connexin protein family.
What is ectodermal dysplasia syndrome?
Ectodermal dysplasias is a group of conditions in which there is abnormal development of the skin, hair, nails, teeth, or sweat glands.
What are the symptoms of Hypohidrotic ectodermal dysplasia?
HED is primarily characterized by partial or complete absence of certain sweat glands (eccrine glands), causing lack of or diminished sweating (anhidrosis or hypohidrosis), heat intolerance, and fever; abnormally sparse hair (hypotrichosis), and absence (hypodontia) and/or malformation of certain teeth.
What is Hay Wells syndrome?
Ankyloblepharon-ectodermal dysplasia-cleft lip/palate (AEC) syndrome, which is also known as Hay-Wells syndrome, is a rare disorder characterized by a wide variety of symptoms that can affect the skin, hair, nails, teeth, certain glands, and the hands and feet.
How is ectodermal dysplasia passed down?
Hypohidrotic ectodermal dysplasia has several different inheritance patterns. Most cases are inherited in an X-linked pattern and are caused by mutations in the EDA gene. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes .
Is Amelogenesis imperfecta hereditary?
Amelogenesis imperfecta can also be inherited in an autosomal recessive pattern ; this form of the disorder can result from mutations in the ENAM or MMP20 gene. Autosomal recessive inheritance means two copies of the gene in each cell are altered.
What is the survival rate of Noonan syndrome?
Overall, late survival in children with Noonan syndrome and cardiac defects was good (91 ± 3% at 15 years), although significantly worse for those with Noonan syndrome-HCM (P < . 01).
Is Noonan syndrome a disability?
Noonan syndrome is a genetic condition that typically includes heart abnormalities and characteristic facial features. About one-third of affected children have mild intellectual disability. Noonan syndrome may be inherited in up to 75 per cent of cases.
What did Clouston syndrome do to the body?
Clouston (1929) described members of a large French Canadian family with a form of ectodermal dysplasia affecting predominantly the nails, hair, and skin. Sweating was normal. Fingernails and toenails were short, thick, and slow growing; in some cases the nails were absent.
What kind of dysplasia is Clouston syndrome?
Clouston syndrome is a form of ectodermal dysplasia that is characterized by abnormalities of the skin, hair and nails.
Where does the last name Clouston come from?
