The life expectancy is calculated by adjusting remaining life expectancy directly and not mortality . Many rare diseases have limited information. Nerve growth factor (NGF), which is produced and released by brain cells, is involved in the regulation of choline acetyltransferase activity,11-13 which is highly expressed in regions of the central nervous system innervated by the magnocellular cholinergic neurons of the basal forebrain including the hippocampus, olfactory bulb, and neocortex. Any child with these skin markings and seizures should be further evaluated for HME as well as other brain malformations. Fetal MRI may be useful for confirmation of diagnosis in cases of suspected lobar holoprosencephaly.
