Roberts syndrome is a rare genetic disorder characterized by symmetrical reductive limb malformation and craniofacial abnormalities. It is caused by mutation in the "Establishment of cohesion 1 homolog 2" genes, resulting in the loss of acetyltransferase activities and manifesting as premature centromere separation in metaphase chromosomes.
