Top Cities for Turner Syndrome Clinical Trials
Turner Syndrome clinical trials are recruiting across 13 cities. Here are the cities with the most active studies:
Turner Syndrome Trial Phases
4 research organizations are sponsoring turner syndrome trials.
About Turner Syndrome
Turner syndrome is a chromosomal condition affecting females, caused by a missing or partially missing X chromosome. It causes short stature, delayed puberty, and may affect the heart and other organs. Treatment includes growth hormone therapy, estrogen replacement, and monitoring for associated conditions.
Clinical trials are advancing new treatments for turner syndrome. Currently, 5 studies are recruiting a combined 1,126 participants across the United States. Research is being conducted by 4 organizations including Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), The University of Texas Health Science Center, Houston, Ascendis Pharma A/S and 1 others.
2026 Turner Syndrome Research Landscape
As of October 2026, the turner syndrome clinical trial landscape includes 5 actively recruiting studies across 13 cities in the United States. These studies are collectively seeking 1,126 participants, with an average enrollment target of 225 per study.
The research spans multiple phases of development: 1 study is in PHASE3, 1 study is in PHASE4. The presence of Phase 3 trials indicates that some turner syndrome treatments are in late-stage testing and may be approaching regulatory review.
Research is being led by 4 different organizations, including Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), The University of Texas Health Science Center, Houston, Ascendis Pharma A/S, Children's Mercy Hospital Kansas City.
Geographically, turner syndrome trials are most concentrated in Bethesda, Maryland (2 trials); Houston, Texas (1 trial); Palo Alto, California (1 trial); Sacramento, California (1 trial); Aurora, Colorado (1 trial) and 7 other cities.

Turner Syndrome: Genetic Considerations
Background: Turner syndrome (TS) is a rare genetic condition. It happens when a person is born missing all or part of an X sex chromosome. People with TS can have heart defects, short stature, autoimmune conditions, and malformations. Many women with TS never have periods and cannot conceive; however, some women have normal ovaries (egg cells). Researchers want to learn more about why some women ...
UTHealth Turner Syndrome Research Registry
The investigators will conduct genetic comparisons between Turner Syndrome (TS) patients with and without Bicuspid Aortic Valve (BAV) to identify causative agents of BAV in people with TS. The investigators will correlate the patterns and prevalence of structural heart defects in TS women with emerging molecular data to identify patients who are at high risk for cardiovascular complications
Gonadal Tissue Freezing for Fertility Preservation in Individuals at Risk for Ovarian Dysfunction, Premature Ovarian Insufficiency and Clinically Indicated Gonadectomy
Background: Turner Syndrome, galactosemia, and premature ovarian insufficiency are all conditions that may make it very hard or impossible for a person to become pregnant and have their own child. Researchers want to learn more about why this happens and if freezing Gonadal tissue allows for fertility preservation. Objective: To find out why people with certain conditions have can have prematur...
