Which are characteristic of Turner syndrome?
Features of Turner syndrome may include a short neck with a webbed appearance, low hairline at the back of the neck, low-set ears, hands and feet that are swollen or puffy at birth, and soft nails that turn upward. Stature. Girls with Turner syndrome grow more slowly than other children.
What causes webbed neck?
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.
Which chromosome is affected in Turner syndrome?
Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects.
What happens if you have Monosomy?
It causes many traits and problems. Girls with TS are shorter than most girls. They don’t go through normal puberty as they grow into adulthood. They may also have other health problems, such as heart or kidney problems.
Can webbed neck Be Fixed?
The lateral approach with a shift of glabrous skin flap to the back, which we performed, allows for effective reduction of the webbed neck, excision of bands of the connective tissue and correction of the low hairline on the side of the neck.
What is webbing of the neck in newborn?
A baby born with Noonan syndrome may have a short neck, with excess skin where the neck joins the shoulders. This can make the neck seem broad and is sometimes called “webbing.” Frequently there are differences in the eyes, including strabismus (cross-eyedness), nystagmus (eye tremors) and very bright blue-green iris.

Is Turner syndrome a dominant or recessive trait?
Turner syndrome only occurs in females. Noonan syndrome, sometimes inappropriately called male Turner syndrome, can occur in males or females. It is an autosomal dominant genetic disorder and is not a chromosomal disorder.
What is an example of monosomy?
Monosomy: Missing one chromosome from a pair. For example, if a female has one X chromosome (X monosomy) rather than two, she has Turner syndrome.
What is webbed neck?
A webbed neck, or pterygium colli, is a congenital skin fold that runs along the sides of the neck down to the shoulders. There are many variants.
