What causes neck webbing?

A congenital, usually bilateral, thick web-like fold of skin that extends from the acromion to the mastoid process. This deformity is associated with Turner Syndrome and Noonan Syndrome.

What is webbed neck syndrome?

Definition. Pterygium colli is a congenital skin fold that runs along the sides of the neck down to the shoulders. It involves an ectopic fibrotic facial band superficial to the trapezius muscle. Excess hair-bearing skin is also present and extends down the cervical region well beyond the normal hairline. [

Is webbing of the neck normal?

Webbing of the neck (pterygium colli) is a frequent finding in Turner syndrome, resembling some cases of Klippel-Feil syndrome. This may be corrected surgically, both for functional and cosmetic reasons. Turner syndrome patients typically have a broad chest, with widely spaced nipples and mild pectus excavatum.

What is a Noonan syndrome?

What causes Noonan's disease?

Noonan syndrome is caused by a faulty gene, which is usually inherited from one of the child's parents. There's no evidence to suggest the genetic fault is caused by environmental factors, such as diet or exposure to radiation.

Do people who suffer from Edward syndrome live very long?

The survival rate varies for babies born with Edwards syndrome (trisomy 18): Between 60% and 75% survive to their first week. Between 20% and 40% survive to their first month. No more than 10% survive past their first year.

What causes Turner syndrome?

Turner syndrome is caused by partial or complete loss (monosomy) of the second sex chromosome. Chromosomes are found in the nucleus of all body cells. They carry the genetic characteristics of each individual and they come in pairs. We receive one copy from each parent.

What is Beckwith Wiedemann syndrome?

Beckwith-Wiedemann syndrome is a genetic disorder commonly characterized by overgrowth. The severity of this disorder varies widely in children and is usually recognized at birth, when a child is born with several features of Beckwith-Wiedemann syndrome. However, few children have all the associated characteristics.

Which characteristic is commonly associated with Turner syndrome?

Turner syndrome is a chromosomal condition that affects development in females. The most common feature of Turner syndrome is short stature, which becomes evident by about age 5. An early loss of ovarian function (ovarian hypofunction or premature ovarian failure) is also very common.

Is Turner syndrome a disability?

Turner syndrome is not considered a disability, although it can cause certain learning challenges, including with learning mathematics and with memory. Most girls and women with Turner syndrome lead normal, healthy, productive lives with proper medical care.

What is the difference between Turner syndrome and mosaic Turner syndrome?

In classical Turner syndrome, an X chromosome is completely missing. This affects about half of all people with TS. Mosaic Turner syndrome, mosaicism, or Turner mosaicism is where the abnormalities occur only in the X chromosome of some of the body's cells.

What is Pallister Killian syndrome?

This condition is characterized by extremely weak muscle tone (hypotonia) in infancy and early childhood, intellectual disability, distinctive facial features, sparse hair, areas of unusual skin coloring (pigmentation), and other birth defects.

Affected children have distinctive facial features and experience intellectual disability, delays in reaching developmental milestones, impaired ability to speak, and can have recurrent seizures, and breathing pattern abnormalities.

What is Fabry disease?

Fabry disease is a rare inherited disorder of glycosphingolipid (fat) metabolism resulting from the absent or markedly deficient activity of the lysosomal enzyme, α-galactosidase A (α-Gal A). This disorder belongs to a group of diseases known as lysosomal storage disorders.

General Discussion. Mowat-Wilson syndrome (MWS) is a rare genetic disorder that may be apparent at birth or later in childhood. MWS is characterized by intellectual disability, distinctive facial features and seizures.

Who is most likely to get Turner syndrome?

Turner syndrome is a genetic condition found in females only. It affects about 1 in every 2,500 girls. Girls who have this condition usually are shorter than average and infertile due to early loss of ovarian function.

What is Mosaic Turner's syndrome?

Mosaic Turner syndrome (TS) is a condition in which cells inside the same person have different chromosome packages. Mosaic TS can affect any cell in the body. Some cells have X chromosomes and some don't. Every 3 out of every 10 girls with TS will have some form of Mosaic TS.
