Genetics of Spina Bifida and Anencephaly - Full Text View

Sponsored by:	Duke University
Information provided by:	Duke University
ClinicalTrials.gov Identifier:	NCT00636233

Purpose

The goal of this research study is to discover the genetic and environmental factors that contribute to the cause of neural tube defects such as spina bifida and anencephaly. Ultimately, this type of research may result in improved diagnosis, improved treatment and possibly prevention.

Biospecimen Retention: Samples With DNA

Biospecimen Description:

Whole blood, serum, saliva, cord blood, fetal tissue, cultured fetal cells

Estimated Enrollment:	10000
Study Start Date:	May 1993
Estimated Study Completion Date:	April 2009
Estimated Primary Completion Date:	April 2009 (Final data collection date for primary outcome measure)

Groups/Cohorts
Spina Bifida Individuals with spina bifida and their family members
Anencephaly Fetuses with anencephaly, parents and siblings
Neural Tube Defect Individuals with neural tube defects other than spina bifida and anencephaly and their family members

Detailed Description:

Participation in the study is entirely voluntary. Any family with at least one family member with a neural tube defect is eligible to participate.

Participation involves:

Completing a written consent form for participation in the study
A phone conversation to collect family and medical information
The collection of blood samples from the individuals with NTDs, their siblings, and parents
For current pregnancies, provide a fetal DNA sample (cord blood, fetal tissue or amniotic fluid)
Reviewing the medical records and x-rays/MRIs/ultrasounds of the individuals with an NTD
Collection of photographs of the individuals with an NTD

Eligibility

Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No
Sampling Method:	Probability Sample

Study Population

Any individual with a neural tube defect and their family members. Any current pregnancy affected by anencephaly.

Criteria

Inclusion Criteria:

At least one family member with a neural tube defect
Individual with the neural tube defect is available to give a DNA sample
If anencephaly must be a current pregnancy or have a DNA sample stored from a previous pregnancy that could be shared

Exclusion Criteria:

No DNA sample available from individual with the neural tube defect in the family
