Prenatal Diagnosis of Unbalanced Translocations in Recurrent Pregnancy Losses in Two Couples
Funding None.
Abstract
Unbalanced translocation is a type of chromosomal abnormality where a portion of one chromosome is attached to another chromosome, resulting in an imbalance in the genetic material. This can lead to adverse pregnancy outcomes in the form of recurrent pregnancy loss, developmental problems, or major structural anomalies, depending on the specific chromosomes and regions involved. This can happen de novo during gametogenesis or it can be inherited from a parent who carries a balanced translocation. For a couple where one partner is a carrier of balanced translocation, there is a need for a detailed genetic counseling regarding the ideal test to be done for diagnosis, options of assisted reproduction, and limitations of these tests. We aim to highlight these aspects through two case illustrations: a first couple who were carriers of balanced translocation and a second couple who had normal tests.
