Turner syndrome is a chromosomal disorder that usually affects development in females. Symptoms differ among individuals, but may include shortened stature, infertility, extra skin on the neck (webbed neck), puffiness or swelling (lymphedema) of the hands and feet, skeletal abnormalities, heart defects, and kidney problems. Females without Turner syndrome have 2 full X chromosomes in each of their cells. An individual with Turner syndrome is missing all or part of one X chromosome. Although it is genetic, it is typically not inherited. Treatment may include growth hormone therapy for short stature and estrogen therapy to help stimulate sexual development. Assisted reproduction techniques can help some women with Turner syndrome become pregnant. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
