Genetic Mutational Analysis of Saliva or Buccal Mucosa Samples From Patients With Embryonal or Alveolar Rhabdomyosarcoma

February 4, 2026 updated by: Children's Oncology Group

Genetics of Embryonal and Alveolar Rhabdomyosarcoma Study (GEARS)

This research trial studies genetic mutations in saliva or buccal mucosa samples from patients with embryonal or alveolar rhabdomyosarcoma. Identifying gene mutations may help doctors learn about the prognosis of patients with embryonal or alveolar rhabdomyosarcoma.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

PRIMARY OBJECTIVES:

I. To identify novel recurrent de novo germline mutations among rhabdomyosarcoma (RMS) case-parent trios.

II. To identify the frequency of de novo germline mutations in cancer predisposition genes among RMS case-parent trios.

SECONDARY OBJECTIVES:

I. To conduct ?deep phenotyping? of children diagnosed with RMS utilizing questionnaire data and information from medical records.

OUTLINE:

Patients and their parents undergo collection of saliva or buccal mucosa samples for genetic mutational analysis. Germline deoxyribonucleic acid (DNA) from saliva or buccal mucosa is evaluated via whole exome sequencing.

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

No older than 50 years (Child, Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Procedure: Biospecimen Collection
Undergo saliva or buccal mucosa collection

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
Novel recurrent de novo germline mutation identification
Time Frame: Up to 3 years
Will analyze de novo single-nucleotide variants (SNVs), copy-number variants (CNVs), and insertions/deletions (INDELs) obtained through next-generation exome sequencing of rhabdomyosarcoma (RMS) case-parent trios.
Up to 3 years
Frequency of de novo germline mutations in cancer predisposition genes
Time Frame: Up to 3 years
Will conduct targeted sequencing using samples collected from the case and his/her parents in order to determine the prevalence of novel de novo mutations in cancer-syndrome genes associated with RMS.
Up to 3 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
Measure Description
Time Frame
Deep phenotyping of children diagnosed with rhabdomyosarcoma utilizing questionnaires and medical record information
Time Frame: Up to 3 years
Analyses will be descriptive in nature.
Up to 3 years

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
