Cet article porte sur trois femmes, porteuses d’une maladie génétique qui affecte la vision, héritée de leur père et susceptible de se transmettre à leurs fils, reçues en consultation de diagnostic prénatal par une généticienne et une psychanalyste. À travers leurs interrogations sur ce qui leur a été transmis, sur ce qu’elles risquent de transmettre et ce à quoi elles se risquent en concevant un enfant, c’est la filiation Père-Fille-Enfant qui est au cœur de leur questionnement. La façon pour chacune de s’inscrire dans cette filiation oriente leur décision de garder ou d’interrompre la grossesse d’un garçon qui serait malade potentiel.

Daughters and their Father This article explores the cases of three women, each carrying a genetic illness affecting sight and inherited from their father. The women were received for prenatal diagnosis consultations by a geneticist and psychoanalyst, as transmission of their genetic illness was possible to any son they might go on to have. The uncertainties surrounding what had been transmitted to them were great, as were those associated with what they themselves risked transmitting and the risks they were running in conceiving a child. Father-Daughter-Child filiation lay at the heart of their questioning. Their decision to either keep or terminate a pregnancy involving a male child at risk of developing the illness entirely depended on how they positioned themselves within this transgenerational chain.
