Monosomy 14

Monosomy is a form of aneuploidy with the presence of only one chromosome (instead of the typical two in humans) from a pair, which affects chromosome 14. Fetuses with monosomy 14 are not viable.[1] Only mosaic cases exist and these usually present with severe symptoms such as intellectual disability, ocular colobomata, microcephaly, and seizures.[2][3]
