Purpose

The purpose of this research is to determine if saliva samples can be used as an alternate sample type to test for fragile X. By using saliva instead of blood, it would be easier for patients to have fragile X testing.

Condition
Fragile X Syndrome


Study Type:	Observational
Study Design:	Observational Model: Cohort Time Perspective: Prospective

Biospecimen Retention: Samples With DNA

In some cases, the de-identified, residual saliva specimen may be used in quality assurance; it may be used in clinical testing as a control; it may be used for future research studies.


Estimated Enrollment:	100
Study Start Date:	July 2012
Estimated Study Completion Date:	December 2012
Estimated Primary Completion Date:	December 2012 (Final data collection date for primary outcome measure)

Groups/Cohorts
Fragile X full mutation (affected) Individual whose previous blood specimen was tested at Esoterix Genetic Laboratories and molecular analysis for fragile X revealed >200 CGG repeats with abnormal methylation pattern; interpretation is full mutation for fragile X syndrome
Fragile X premutation (carriers) Individual whose previous blood specimen was tested at Esoterix Genetic Laboratories and molecular analysis for fragile X revealed 55-200 CGG repeats with normal methylation pattern; interpretation is premutation carrier of fragile X syndrome
Fragile X intermediate Individual whose previous blood specimen was tested at Esoterix Genetic Laboratories and fragile X molecular analysis revealed 45-54 CGG repeats; interpretation is intermediate, not a carrier of a fragile X expansion mutation

Detailed Description:

Saliva samples will be prospectively collected from subjects who have previously been tested by Esoterix Genetic Laboratories, LLC using blood specimens and diagnosed as fragile X intermediates, premutations (carriers) or full mutations (affected). Results from fragile X testing with saliva will be compared to results from the blood sample that was previously submitted to Esoterix Genetic Laboratories for testing.

Data from this study will be used for regulatory submissions.

Eligibility


Ages Eligible for Study:	Child, Adult, Senior
Sexes Eligible for Study:	All
Accepts Healthy Volunteers:	No
Sampling Method:	Non-Probability Sample

Study Population

Fragile X full mutations (affecteds), fragile X premutations (carriers), and fragile X intermediates who previously had fragile X testing through Esoterix Genetic Laboratories. Subject population will be in the US.

Criteria

Inclusion Criteria:

Subject has previously been identified through molecular testing at Esoterix Genetic Laboratories as a Fragile X intermediate, premutation (carrier) or full mutation (affected).
In the opinion of the subject's physician, the subject is medically stable and able to provide the required quantity of saliva.
If Subject is at least 18 years of age:
Subject must be willing to give written informed consent
Subject must be willing to comply with the collection procedure
If Subject is under 18 years of age, the legally authorized representative must give written informed consent and agree to comply with study procedures.

Exclusion Criteria:

Subject has been determined to be an individual with a normal FMR1 gene.
Subject has a known medical condition that would cause risk to the donor or, if relevant, the fetus as a result of saliva collection.
