Turners Syndrome

Turner syndrome is a genetic condition affecting females, characterized by the partial or complete absence of one X chromosome. Physical manifestations often include a webbed neck, low-set ears, broad chest, and upward-turned fingernails and toenails.

Current Research being Conducted

We are examining the if mosaic karyotype modifies the neurocognitive and psychosocial profiles typically seen in females with Turner syndrome. The goal of this study is to increase our understanding of the relationship between genetics, brain development and behavior.

Treatments or Prevention

There is no cure for Turner syndrome, but therapies have been developed that can improve physical development. With proper medical care, females with Turner syndrome should be able to lead full, productive lives. The primary therapies for affected individuals are growth hormone therapy and estrogen therapy.

Symptoms

Subtopic
Wide or weblike neck Low-set ears Broad chest with widely spaced nipples High, narrow roof of the mouth (palate) Arms that turn outward at the elbows Fingernails and toenails that are narrow and turned upward Swelling of the hands and feet, especially at birth Slightly smaller than average height at birth Slowed growth Cardiac defects Low hairline at the back of the head Receding or small lower jaw Short fingers and toes

Interesting Related Features

Females with Turner syndrome may develop a variety of distinctive physical features including a short neck with a webbed appearance, a low hairline at the back of the head, low-set ears, and narrow fingernails and toenails that are turned upward.

Community Support Services

Girls with Turner syndrome are entitled to receive high-dose growth hormone therapy as soon as it becomes apparent that they're not growing normally. It will help make them taller in adulthood. Growth hormone therapy is a daily injection, started at around 5 or 6 years of age or later.

History Of Turner Syndrome

Turner syndrome was first discovered in 1938 by Dr. Henry Turner while studying a group of 7 girls who all had the same unusual developmental and physical features. Though most people today refer to the condition as Turner syndrome or TS, your doctor may call it gonadal dysgenesis. This is because one of the defining characteristics of TS is that it affects the ovaries—the primary female gonads or sex glands. Abnormal development or premature insufficiency of the ovaries affects their ability to produce estrogen. This can result in a variety of problems, including infertility, irregular or absent menstrual periods, early menopause, and osteoporosis.

What Causes Turner Syndrome

Turner syndrome occurs when part or all of an X chromosome is missing from most or all of the cells in a girl's body. A girl normally receives one X chromosome from each parent. The error that leads to the missing chromosome appears to happen during the formation of the egg or sperm.
