Turner Syndrome Awareness Month

Overview

Turner syndrome happens when a girl is born missing all or part of one of her X chromosomes, most often showing up as a 45,X karyotype or a mosaic pattern. It's one of the more common chromosomal conditions in girls and touches everything from how they grow to how their ovaries work to how their heart develops.

Impact

Girls and women with Turner syndrome often live with short stature, delayed or absent puberty, and infertility, plus a higher lifetime risk of heart disease, thyroid issues, hearing loss, and learning differences. All of that can weigh on self-image, school, work, and family planning, which is why coordinated lifelong care across specialties makes such a difference for patients and families.

Medical Overview

Diagnosis is confirmed with a karyotype or chromosomal microarray, and the clues that usually prompt testing include lymphedema in infancy, short stature, a webbed neck, or primary amenorrhea (never starting periods). Recombinant human growth hormone can improve adult height when it's started early, and estrogen replacement is used to bring on puberty, protect bone health, and prepare the uterus for potential pregnancy with assisted reproduction. Cardiac surveillance is a huge part of care because bicuspid aortic valve, aortic coarctation, and aortic dilation are common and can lead to dissection if missed. The 2024 international consensus guidelines really emphasize smooth transitions from pediatric to adult care, regular heart imaging, screening for autoimmune and metabolic issues, and attention to mental health and learning needs. Fertility preservation is also being discussed earlier, often in adolescence, so families have options later.
