Prenatal Molecular Characterisation by CGH+SNP-ARRAY of Supernumerary Marker Chromosomes and de Novo Apparently Balanced Reciprocal Translocations (compass)

February 20, 2024 updated by: Centre Hospitalier Universitaire Dijon
In the prenatal period, les supernumerary marker chromosomes (SMC) and de novo apparently balanced reciprocal translocations are revealed by foetal karyotyping, which does not always make it possible to determine whether the anomaly is balanced or not and does not reveal uniparental disomy. The presence of these chromosomal rearrangements raises a difficult question for genetic counselling during pregnancy because of the risk of intellectual deficiency in the foetus. CGH+SNP-Array can provide information concerning 1) the balanced or not nature of these translocations 2) the presence or not of euchromatin in the SMC 3) the presence or not of uniparental disomy.
