Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for people with Turner syndrome, and their biological parents and other relatives, to build a genetic database.

Age
From 1 Day to 110 Years.
Sex
All sexes can join.
Disease stage
Turner syndrome confirmed by a karyotype (a chromosome test). Family members do not need to have it.
Biomarker or test result
Turner syndrome diagnosis based on karyotype, for patients.

Main reasons for not taking part

  • A diagnosis other than Turner syndrome.
  • People from protocol 20CH0126 who do not agree to be referred to the 17I0122 NIAID study.

  • Diagnosis other than Turner syndrome

Other criteria

  • INCLUSION CRITERIA:; Turner syndrome diagnosis based on karyotype; Any age; Biological parent of Turner syndrome patient; Relatives of Turner syndrome patient; The subject from protocol 20CH0126 will enroll in this study only when they agree to be referred to the 17I0122 NIAID study. They can withdraw participation in the 17I0122 study if they do not want to have their genetic data in this database

About the trial

What the trial wants to find out

Background:

Read full original descriptionShow less

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 with TS are fertile and others are not. To do this, they need to be able to compare the genes of many women who have TS.

Objective:

To create a genetic database of people with TS.

Eligibility:

People of any age with TS currently enrolled, or interested in enrolling in protocol 20-CH-0126. Biological parents and other relatives are also needed.

Design:

Participants who agree to join this study will be asked to enroll in a second study; that study is called "NIAID Centralized Sequencing Protocol" (Protocol No. 17I0122).

Participants will have 1 study visit. They may fill out a survey or do an interview. They will provide blood, saliva, or other tissue samples. Those samples will be used for genetic tests. The visit will take 1 hour.

The information collected in those tests will be collected for use in the database created as part of this study.

The 2 groups in the trial

  • Patient

    Turner Syndrome

  • Family member

    Family member of patient with Turner Syndrome

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
