Our first child is called Amandine,
What a lovely nursery rhyme.
Our second was Valentin,
Our greatest sorrow,
And from the discovery of genetic risks.
From problems to tragic consequences,
Was born an association.
Which henceforth bears his name.
Now Jean-Baptiste GwenaŽl, AnaŽlle are everything to us,
Our most beautiful victory over life.

Frequency of the Problem


One person in 150 carries an abnormality in the structure or number of chromosomes. These abnormalities can be accidental or hereditary. In the latter case, the symptoms and their consequences can reoccur at each pregnancy.

This genetic problem affects many people, some without their knowledge. The "healthy carrier" is perfectly normal, without any specific pathology. The problem might only be apparent at the conception of children.

Testing a family is done with a simple blood test, which establishes a karyotype. Prenatal diagnosis is undertaken by amniocentesis or chorioncentesis (CVS).

For hereditary abnormalities, the risk of encountering the following problems is 50%.

Symptoms and Consequences

  • Children with a more or less serious psychomotor disability
  • Death in utero or at birth
  • Termination following the results of a prenatal test
  • Spontaneous miscarriage, repetitive and often at an early stage
  • Infertility, sometimes apparent

For the Parents


A battle that sometimes lasts many years to have a child

Psychological distress due to the symptoms mentioned above but also due to the learning and acceptance of the problem and living with its consequences

Incomprehension from the general public

Difficulty in obtaining access to family blood tests the only means today to forewarn and reduce the problem, in the absence of any treatment.

A lack of public information.

A lack of training within the medical profession to aid better understanding of the problems, to provide better guidance and explanations to families.

A lack of multi-disciplinary centres to welcome and help families in all aspects, and a lack of centres for disabled children and disabled adults.

Objectives of the association

  • You, or your child, are the carrier of a Chromosomal abnormality such as a translocation, inversion, absence, insertion, deletion, duplication or even monosomy, trisomy, tetrasomy or pentasomy.
  • You are surprised, discouraged, helpless in the face of this problem, which makes having healthy children a challenge.
  • You have many questions but daren't ask your doctor
  • You'd like to speak to people with similar experiences and hear of their problems and solutions

  • The Valentin Association is here to listen to you, to answer your questions and meet your expectations
