UTHealth Turner Syndrome Research Registry

November 27, 2023 updated by: Siddharth Prakash, The University of Texas Health Science Center, Houston

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

Detailed Description

Turner syndrome (TS) is a common chromosomal disorder that affects approximately 1 in 2500 live female births. Complete or partial monosomy of one of the X chromosomes in a female is associated with various congenital heart defects (CHDs), which include aortic dilatation, coarctation of aorta and BAV. Congenital cardiovascular defects related to CHD are the leading cause of death in women with TS. The Turner Syndrome Network Registry (TRN Registry) and genetic sample repository can address gaps in knowledge of CHD in TS by facilitating the recognition of demographic and genetic patterns. TRN Registry-based research can improve surveillance of TS patients who are at risk for CHD and provide valuable insight into genetic components of CHD.

The investigators will recruit TS patients into the TRN Registry and obtain blood and/or saliva samples after informed consent. The genetic diagnosis of TS will be confirmed using chromosomal microarrays. The array data will be also be used to identify genomic copy number variants, and rare variants in protein coding genes will be determined by exome sequencing. The investigators will derive induced pluripotent stem cells from some participants to determine why CHD is so prevalent in TS. CHD risk genes will be identified in comparisons between TS cases with and without congenital heart defects. To facilitate these comparisons, the investigators will abstract the demographic and medical data of registry participants from questionnaires and medical records. Imaging will be used to confirm the diagnosis of CHD and to determine the prevalence and severity of additional cardiovascular defects.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Sampling Method

Probability Sample

Study Population

The study population consists of females diagnosed with Turner Syndrome. This diagnosis can be based on physical symptoms (e.g. short stature, developmental delay, pubertal delay, etc.) or karyotype (e.g. 45X/46XX mosaic, 45X, etc.).

Description

Inclusion Criteria:

  • Diagnosis of Turner Syndrome

Exclusion Criteria:

  • Diagnosis excluding Turner Syndrome

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame

Time Frame: 10 years
Imaging data
10 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
