A 9-year-old girl presents for annual well visit. Mother expresses a concern for her daughter’s short stature. By mother’s report, the girl has always been petite and is the shortest in her class. Family genetics for height indicate tall stature; she is notably small for the family.
Her past medical history is unremarkable other than an ongoing issue of reoccurring otitis media. Birth history indicates that she was born full term, SVD. Birth weight was 6 lbs., 6 ozs., and length was normal. Review of systems is unremarkable. Overall, she is described as very healthy. She denies any medical complaints. School performance is good but she requires additional support with math.
Physical examination reveals she is well appearing though short for age. Height is 2.5th percentile, and weight is 30th percentile. She is prepubertal. Her cardiac and respiratory exams are normal. Mild high arched palate is noted. Mild cubitus valgus is noted. The remainder of examination is unremarkable.
Discussion: The diagnosis is Turner syndrome (TS).
Turner syndrome is a syndromic condition resulting from complete or partial absence of the second sex chromosome. Diagnosis is made by chromosome analysis. The most common features of Turner syndrome include significant short stature, gonadal dysgenesis and ovarian failure leading to lack of or incomplete puberty, cardiac anomalies, and renal anomalies. Since short stature is the most common presenting sign of Turner syndrome, a chromosome analysis is indicated in all girls
Mosaicism can occur, leading to a milder presentation and often making recognition of the condition more difficult. Patients with mosaicism may have less significant short stature and may experience spontaneous pubertal onset but may not have enough ovarian function to complete the pubertal process. In such cases, failure to progress completely through the puberty process and achieve menarche often leads to medical attention.
Coarctation of the aorta and bicuspid aortic valves are the most common cardiac anomalies. Hypertension is also common. Renal anomalies include horseshoe kidneys or duplication of the collecting system. Urinary tract infections can be common if renal anomalies are present. Patients may also experience frequent/reoccurring otitis media. Pigmented nevi (benign) are common in girls with TS. Scoliosis is common, requiring ongoing screening. There is a higher incidence of autoimmune disorders, including acquired hypothyroidism, celiac disease, and diabetes. Screening for these conditions will be required every 1 to 2 years depending on age. Learning differences can occur at slightly higher incidence and may include visual spatial deficits, nonverbal learning disability, and attention deficit. Psychosocial issues may include difficulty with social skills and interactions with age-matched peers.
Newly diagnosed patients with TS require endocrinology, genetics, and cardiology evaluations and a baseline renal ultrasound. Patients are managed by the Division of Endocrinology for treatment of growth and pubertal issues but also for overall disease management and surveillance. Treatment of short stature includes growth hormone therapy, which can improve final height. Hormonal therapy to initiate and maintain puberty is indicated if gonadal dysgenesis results in lack of spontaneous pubertal onset or incomplete puberty. Gonadal dysgenesis puts girls with TS at significant risk for infertility. Counseling and psychosocial support may be indicated to address issues related to short stature, delayed puberty, adjustment to diagnosis, and peer relationships. Support groups are valuable for patients and parents.

“Spring Fling for Turner Syndrome,” hosted by the Division of Endocrinology Turner Syndrome Program at CHOP, is scheduled for May 18, 2013. - Learn and Connect
Learn and Connect sessions are held twice in the fall at the Voorhees, New Jersey, Specialty Care Center, and twice in the spring at our King of Prussia, Pennsylvania, Specialty Care Center. The sessions are for parents of girls with Turner syndrome. The goal is to bring parents together to network with other parents and provide an opportunity to learn about medical issues and parenting issues common in TS.
