In rare cases (i.e., trisomy 15q25-qter), affected infants may have hydrocephalus, a condition characterized by inhibition of the normal flow of cerebrospinal fluid (CSF) within and abnormal widening (dilatation) of the cerebral spaces of the brain (ventricles), causing accumulation of CSF in the skull and potentially increased pressure on brain tissue.
