NCT03087526

Brief Summary

The purpose of this study is to develop and validate an analytical and clinical NIPD test for triplet repeat diseases by isolated circulating fetal trophoblastic cells (CFTC) analysis from maternal blood, searching for the familial mutation in families at risk of having one of the following triplet repeat diseases: Huntington's disease, Steinert Myotonic dystrophy, Fragile X syndrome, spinocerebellar ataxia (SCA) 1, 2 and 3.

Outcome Measures

Primary Outcomes (1)

  • Concordance rate between cell-based genetic non invasive prenatal test and gold standard prenatal test (choriocentesis or amniocentesis).

    Analysis of the concordance of the prenatal results obtained by our new NIPD (Non-Invasive Prenatal Diagnosis) approach and those blindly obtained during the gold-standard prenatal genetic test will be carried out for each pregnant woman participating in the study.

    30 months

Secondary Outcomes (1)

  • Non Invasive Prenatal Diagnostic test failure rate.

    30 months

Study Arms (1)

Couple at risk of transmitting a triplet-repeat disease

EXPERIMENTAL

Expectant couple (pregnant woman between 9 and 34 weeks of gestation and her spouse) at risk of transmitting a triplet-repeat related genetic disease among Huntington disease, Myotonic Dystrophy type 1, Fragile X syndrome, Spinocerebellar Ataxia type 1, Spinocerebellar Ataxia type 2, Spinocerebellar Ataxia type 3

Genetic: Non invasive prenatal diagnosis

Interventions

Search for the familial mutation on isolated circulating fetal trophoblastic cells from maternal blood

Couple at risk of transmitting a triplet-repeat disease

Eligibility Criteria

Age18 Months+
Sexfemale
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • older than 18 years old
  • pregnant woman between 9 and 34 weeks of gestation
  • Couple at risk (based on family history or echographic findings) for one of the following diseases: Huntington's disease, Steinert's myotonic dystrophy, fragile X and spinocerebellar ataxias 1, 2 or 3
  • Written informed consent was obtained for the study
  • Prenatal diagnosis has been programmed for the current pregnancy during which maternal blood is collected
  • Couple molecular diagnosis results for one of the following diseases (Huntington's disease, Steinert's myotonic dystrophy, fragile X and spinocerebellar ataxias 1, 2 or 3 ) MUST BE AVAILABLE.

You may not qualify if:

  • Couple Genomic DNA are unavailable
  • Subjects at risk of transmitting the family disease, but not wishing to know their molecular status
  • individuals under guardianship by court order
