Background: Microcephalic primordial dwarfism (MPD) is a group of rare genetic disorders defined by severe growth restriction of both prenatal and postnatal weight (W), height (H), and particularly head circumference (HC).Objective and hypotheses: To elucidate the genetic origin of the MPD in dizygotic twins.Method: Exome sequencing of 19 genes known to be implicated in microcephaly was performed.Results: Diz...
