Prenatal diagnosis and molecular cytogenetic characterization of de novo partial trisomy 12q (12q24.21 → qter) and partial monosomy 6q (6q27 → qter) associated with coarctation of the aorta, ventriculomegaly and thickened nuchal fold

► We present concomitant del(6)(q27 → qter) and dup(12)(q24.21 → qter). ► The phenotype includes aortic coarctation and ventriculomegaly. ► We discuss the genotype-phenotype correlation.
