A structural anomaly of the brain, in which the developing forebrain fails to correctly separate into right and left hemispheres. Holoprosencephaly is genetically heterogeneous and associated with several distinct facies and phenotypic variability. The majority of holoprosencephaly type 3 cases are apparently sporadic, although clear examples of autosomal dominant inheritance have been described.
