Webbed neck is a characteristic of Turner syndrome.
A webbed neck, also called pterygium colli, is an inherited skin fold that extends from the sides of the neck to the shoulders. There are numerous variations. Webbed necks in infants may seem like loose folds of skin. The skin stretches out as the child matures, making the neck appear minor or nonexistent. It is a characteristic of Turner syndrome, affecting only girls.
Turner syndrome is a hereditary disorder linked to the X chromosome. Instead of having the typical 46 chromosomes, a person with Turner syndrome has 45 chromosomes altogether. In this circumstance, a female is missing either all or part of an X chromosome.
Signs of Turner syndrome include swelling in the hands and feet, kidney or heart problems, and a webbed neck with a broad chest during birth.
