Peter plus syndrome (PPS) is a rare, hereditary (autosomal recessive) disorder characterized by a mutation in the beta-1,3-galactosyltransferase-like gene (chromosome 13q12), which causes impaired glycosylation of several structural and functional proteins throughout the body. Clinical signs and symptoms of PPS are highly variable and include structural malformations affecting multiple organ systems including central nervous system. We aim to discuss a neurosurgeon's perspective to PPS in this report. A 2-year-old boy presented with congenital dysmorphic facies, bilateral central corneal opacities, delayed developmental milestones, short-stature (75cm), rhizomelia with brachydactyly, and history of surgery for anal atresia on the second day of life. Screening craniospinal magnetic resonance imaging revealed mild ventriculomegaly, cavum septum pellucidum, cavum velum interpositum, vermian hypoplasia, and normal spine. Cytogenetic analysis showed a mutation in the beta-1,3-galactosyltransferase-like gene on chromosome 13. Clinical picture in our patient suggested the diagnosis of PPS. Parents often seek ophthalmological consultation due to visual impairment predominantly, and this syndrome largely remains unknown among neurosurgeons. Nonetheless, babies with PPS may present with neurological symptoms such as seizures, spastic diplegia, tinnitus, or hearing loss as well as a life-threatening neurosurgical emergency arising due to raised intracranial pressure. Therefore, the role of neurosurgeon becomes crucial in managing these cases.
