Chromosomal imbalance
WebMay 22, 2012 · By contrast, aneuploidy is an unbalanced genomic state that describes a range of karyotypes. Whole chromosomes can be lost (nullisomy or monosomy) or gained (disomy or trisomy). Additionally, sub-chromosomal regions can be amplified, deleted or translocated (partial aneuploidies). WebIn this context, chromosomal imbalances in syndromic DSD patients may help to identify new genes implicated in DSDs. In this study, we aimed at describing the burden of chromosomal imbalances including submicroscopic ones (copy number variants or CNVs) in a cohort of prenatal syndromic DSD patients, and review their role in DSDs.
