Craniofacial Microsomia: Accelerating Understanding of the Significance and Etiology (CAUSE)

April 18, 2024 updated by: Carrie Heike, Seattle Children's Hospital
The CAUSE study is a multicenter study, with domestic (n=4) and international (n=6) study sites. Children and young adults (ages 0-18) who have microtia and/or craniofacial microsomia and their parents are invited to participate. Children and parents are asked to provide a DNA sample (blood or saliva) and are asked to upload a few photos of their face. Parents are asked a short interview. Participants are able to participate from home or at one of four domestic sites.

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 18 years (Child, Adult)

Accepts Healthy Volunteers

N/A

Sampling Method

Non-Probability Sample

Study Population

All CFM cases, their parents, and their relatives regardless of their sex, race, or ethnicity. The prospective case samples will likely be drawn from outpatient clinics and medical centers, as well as CFM-related social medial networks.

Description

INCLUSION:

Cases:

  • Participant with CFM is 0-18 years of age

  • Participant has diagnosis of at least one of the following conditions:

    • Microtia
    • Anotia
    • Facial asymmetry AND preauricular tag(s)
    • Facial asymmetry AND facial tag(s)
    • Facial asymmetry AND epibulbar dermoid
    • Facial asymmetry AND macrostomia (i.e., lateral cleft)
    • Preauricular tag AND epibulbar dermoid
    • Preauricular tag AND macrostomia
    • Facial Tag AND epibulbar dermoid
    • Macrostomia AND epibulbar dermoid
  • Participant's parent or legal guardian has provided written informed consent prior to enrollment into study (for participants younger than 18 years of age).
  • Participant speaks a language in which they are eligible for consent at their enrolling site

Parents:

  • Parent participant is the biological parent of a case participant already eligible and participating in the CAUSE study. Non-genetic parents will be interviewed about their child's known prenatal and genetic family history but will not be asked to provide DNA or have facial photographs taken.
  • Participant speaks a language in which they are eligible for consent at their enrolling site

Other relatives:

  • Other relatives participants, of any age, are related biologically to a case participant already eligible and participating in the CAUSE study from a multiplex family (multiple affected individuals with CFM).
  • Participant speaks a language in which they are eligible for consent at their enrolling site

EXCLUSION:

Cases:

  • Participant is diagnosed with a known syndrome that involves microtia and underdevelopment of the jaw (Townes-Brocks, Treacher-Collins, Branchiootorenal, Nager, or Miller syndromes).
  • Participant has abnormal chromosome studies (karyotype).
  • Participant has mandibular asymmetry due to deformational plagiocephaly or torticollis.

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
Identify Genetic Variants
Time Frame: Through study completion, an average of 1 year.
To identify genetic variants related to the CFM spectrum using whole genome sequencing
Through study completion, an average of 1 year.

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
Characterize phenotype
Time Frame: Through study completion, an average of 1 year.
To characterize the detailed phenotype in individuals with CFM
Through study completion, an average of 1 year.
Characterize markers
Time Frame: Through study completion, an average of 1 year.
To characterize ancestry markers in individuals with CFM
Through study completion, an average of 1 year.

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. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
