NCT03743948

Brief Summary

The purprose of this study is to develop a single test based on circulating fetal trophoblastic cells (CFTC) analysis from maternal blood, searching for the familial mutation for a wide range of monogenic diseases.

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.

    at 36 month

Secondary Outcomes (1)

  • Non Invasive Prenatal Diagnostic test failure rate.

    at 36 month

Study Arms (1)

Expectant couple at risk of transmitting a monogenic disease.

EXPERIMENTAL

Expectant couple (pregnant woman from 9 weeks of gestation and spouse) at risk of transmitting a monogenic disease among the genes included in the trusight one expanded sequencing kit (Illumina).

Genetic: Non invasive prenatal diagnosis

Interventions

15 pregnant women and their spouses Search for the familial mutation on isolated circulating fetal trophoblastic cells from maternal blood

Expectant couple at risk of transmitting a monogenic disease.

Eligibility Criteria

Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • older than 18 years old
  • pregnant woman between 9 and 34 weeks of gestation
  • Couple undergoing prenatal diagnosis for a monogenic disease caused by point mutation(s)
  • 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 a monogenic disease caused by point mutation(s) 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
