Subtypes of holoprosencephaly and differentiating features (1), (4), (5) Alobar Semilobar Lobar Degree of Almost complete Posterior Rostral and
prosencephalon non-separation cerebral ventral frontal non-separation with holosphere hemispheres lobe fusion.
Holoprosencephaly is a rare congenital anomaly that is characterized by lack of cleavage of the
prosencephalon. Holoprosencephaly can frequently be diagnosed via screening ultrasound at 20 weeks gestation.
At HH stage 10, Mnb mRNA was detected at different levels of the closed neural tube: the prospective
prosencephalon, mesencephalon, rhombencephalon, and spinal cord (Figure 1i).
Labeling of inclusion bodies and some intracytoplasmic staining was notable from the forebrain (
prosencephalon) to the mesencephalon (Figure, panel A).
